The ld linker from binutils 2.22 has --no-copy-dt-needed-entries enabled by
default, which is exactly opposite of earlier versions of the linker.
Previously ld would recursively search libraries linked in by the object's
primary libraries during symbol resolution. Now linker wants all libraries
explicit requested, otherwise one gets a message such as this:
ld: <object file>: undefined reference to symbol '<symbol>'
ld: note: '<symbol>' is defined in DSO <shared library> so try adding it
to the linker command line.
If this message is encountered, the two options are either to explicitly
add it to the linker command as suggested, or use the
--no-copy-dt-needed-entries switch to return the linker to its previous
behavior. In the case of math/pari, libstdc++ was added to the library
list for the plotfltk.o object. This explicit link is required by DragonFly
which is migrated to binutils 2.22 as its default version.
as executables rather than loadable modules
This might cause that the pkg doesn't build on as many platforms as
it did before, but it has a chance to work now.
bump PKGREV
Recent versions of devel/p5-Object-InsideOut optionally uses this
module.
This module provides pseudorandom number generators (PRNGs) that are
based on the Mersenne Twister algorithm. There is a functional
interface to a standalone PRNG, and an OO interface (based on the
inside-out object model as implemented by the Object::InsideOut
module) for generating multiple PRNG objects.

2011-02-26 v1.16 pjacklam (6153 tests)
* Change bigintpm.inc to reflect recent changes in the Math::BigInt
distribution (Peter John Acklam).
2011-02-10 v1.15 pjacklam (6151 tests)
* Include latest version of test scripts from Math-BigInt (closes RT #65580)
(Peter John Acklam).
* Add 00sig.t for testing SIGNATURE, and 01load.t for basic module loading and
giving diagnostics useful for bug tracking (Peter John Acklam).
* Rename pod.t to 02pod.t and pod_cov.t to 03podcov.t and use more generic
code (Peter John Acklam).
* Clean up whitespace (Peter John Acklam).
2011-02-26 v1.36 pjacklam (6362 tests)
* Change bigintpm.inc to reflect recent changes in the Math::BigInt
distribution (Peter John Acklam).
* Use a _nok() function more similar to the one in Math::BigInt::Calc
(Peter John Acklam).
2011-02-08 v1.35 pjacklam (6361 tests)
* Rename files for testing signature, module loading, and POD so the names
are within the 8+3 character limit (Peter John Acklam).
* Rename method _nok_ok() to the correct _nok(). There ought to have been a
test catching an error like that (Peter John Acklam).
* Fix _nok() giving wrong output when second input argument is zero
(Peter John Acklam).
* Fix _nok() so it doesn't modify its second input arg (Peter John Acklam).
* Update the included Devel::CheckLib to most recent version as suggested in
RE #63055 (Peter John Acklam).
* Apply "chmod 0644" to the few test scripts that don't already have that
mode (Peter John Acklam).
2011-02-07 v1.34 pjacklam (6361 tests)
* Rename _num() to _str(). The old _num() did exactly what _str() is supposed
to do, according to the API documentation (Peter John Acklam).
* Add a _num() function which (currently) simply numifies the output from
_str() (Peter John Acklam).
* Clean up whitespace (Peter John Acklam).
* Fix POD errors (Peter John Acklam).
* Add _nok() method. Now the old claim that Math::BigInt::GMP conforms to API
version 2 is actually true (Peter John Acklam).
* Edit the test files that were copied from the Math::BigInt distribution, so
we now test Math::BigInt against Math::BigInt::GMP, not Math::BigInt::Calc.
I had forgotten this when I copied the test files from the Math::BigInt
distribution. This reduces the total test count, since some test are not
executed with Math::BigInt::GMP (Peter John Acklam).
* Replace morse code in 'README' with proper text (Peter John Acklam).
* Include '01-load.t' for explicitly testing module loading (Peter John
Acklam).
* Use more generic code in 'pod.t' and 'pod_cov.t' (Peter John Acklam).
2011-01-30 v1.33 pjacklam (6411 tests)
* Fix _modinv() so that it works the same way as _modinv() in other
Math::BigInt libraries: The output arguments are an object and the
corresponding sign, not undef (Peter John Acklam).
* Include most recent versions of the test files from the Math-BigInt
distribution (bigfltpm.inc, bigfltpm.t, bigintpm.inc, bigintpm.t,
biglog.t, and bigroot.t) (Peter John Acklam).
* Include generic SIGNATURE test file (Peter John Acklam).
* Required version of Math::BigInt is now 1.99_05 (Peter John Acklam).
0.09 Mon Dec 06 2010
- explicit use of of Math::BigInt to avoid confusing Devel::Cover
0.08 Mon Dec 06 2010
- don't short-circuit encoding '0' so it gets proper padding.
* Fix t/matlab.t failing on Windows (RT 64629)
* Applied patch from RT 51669 (POD rendering)
* Applied patch from RT 61334 (fix croak in new_from_string)
* Make reference check less strict in _new_from_row_or_cols (requested by MJD)
Changes 2.06:
* added submatrix() (exactly the same behavior as sec() from PDL, for 2D
matrices)
* t/submatrix.t created
* t/decompose_LR.t created
* !!!NEED documentation for submatrix()
* Compiling OpenMP support (--enable-openmp) now installs a fftw3_omp library,
instead of fftw3_threads, so that OpenMP and POSIX threads (--enable-threads)
libraries can be built and installed at the same time.
* Various minor compilation fixes, corrections of manual typos, and
improvements to the benchmark test program.
* Add support for the AVX extensions to x86 and x86-64. The AVX code works with
16-byte alignment (as opposed to 32-byte alignment), so there is no ABI
change compared to FFTW 3.2.2.
* Added Fortran 2003 interface, which should be usable on most modern Fortran
compilers (e.g. gfortran) and provides type-checked access to the the C FFTW
interface. (The legacy Fortran-77 interface is still included also.)
* Added MPI distributed-memory transforms. Compared to 3.3alpha, the major
changes in the MPI transforms are:
* Fixed some deadlock and crashing bugs.
* Added Fortran 2003 interface.
* Added new-array execute functions for MPI plans.
* Eliminated use of large MPI tags, since Cray MPI requires tags < 224.
* Expanded documentation.
* make check now runs MPI tests
* Some ABI changes — not binary-compatible with 3.3alpha MPI.
* Add support for quad-precision __float128 in gcc 4.6 or later (on x86.
x86-64, and Itanium). The new routines use the fftwq_ prefix.
* Temporarily removed MIPS paired-single support due to lack of available
hardware for testing. We hope to add it back before the final FFTW 3.3
release; meanwhile, users who want this functionality should continue using
FFTW 3.2.x.
* Removed support for the Cell Broadband Engine. Cell users should use FFTW
3.2.x.
* New convenience functions fftw_alloc_real and fftw_alloc_complex to use
fftw_malloc for real and complex arrays without typecasts or sizeof.
Changes:
- Added "jet bundle" framework by Werner Seiler and Joachim Schue,
which includes completion procedure and symmetry analysis for PDE.
- Better splitting of group representations (added Holt-Rees improvement
to meatAxe).
- Added numeric versions of some elliptic integrals and few more elliptic
functions.
- Speeded up FFCGP (finite fields via Zech logarithms).
- New experimental flag (off by default, set via setSimplifyDenomsFlag)
which if on causes removal of irrationalities from denominators.
Usually it causes slowdown, but on some examples gives huge speedup.
It may go away in future (when no longer needed).
- Added experimental framework for theory of computations.
Bug fixes, in particular:
- Numerical solutions of polynomial systems have now required accuracy
(SF 2418832).
- Fixed problem with crashes during tracing.
- Fixed a problem with nested iteration (SF 3016806).
- Eliminated stack overflow when concatenating long lists.

Changes:
- Experimental Texmacs interface and Texmacs format output.
- Guessing package can now guess algebraic dependencies.
- Expansion into Taylor series and limits now work for most
special functions.

unevaluated or produced wrong results.
- Unwanted numerical evaluation should be no longer a problem
(FriCAS interpreter now very strongly prefers symbolic
evaluation over numerical evaluation).

of some correct solutions.
- TeX and MathML format should correctly put parentheses around
and inside sums and products.
- Fixes few problems with handling of Unicode.
This release fixes a bug on x86 when the scale factor of
scale_float(cl_LF, cl_I) exceeded 2^31. In addition, it improves
portability to non-GCC compilers.

Patch 3 fixes the following bug:
The mpfr_atan function calls mpfr_check_range on the unrounded
result (no longer allocated) instead of the rounded result.
Consequence of this bug: possible incorrect or invalid result and/or
incorrect flags if the unrounded result or rounded result is not in
the current exponent range. Or possibly worse if the memory used by
the unrounded result is modified before the return of the function.
This bug has been present since MPFR 2.1.0 (exceptions were not
supported before).
Patch 2 fixes the following bug:
The mpfr_rec_sqrt function can have undefined behavior due to the
call of mpn_add_1 or mpn_sub_1 (from GMP) with a null size, which is
not allowed. The fourth argument of mpn_add_1 or mpn_sub_1 (i.e. the
value that should have been added or subtracted) is here also 0, so
that the consequences are limited. In practice, with the current GMP
version, this yields a small buffer overflow (1 limb, i.e. 32 bits
or 64 bits), as shown by valgrind, with the possible consequences:
a crash, or memory corruption (very unlikely) if another process or
thread modifies the limb at the same time (as in this context, the
value is first read then written back by GMP). This bug has always
been present since the introduction of the mpfr_rec_sqrt function
in MPFR 2.4.0.
Patch 1 fixes the following bug:
If the exponent range has been reduced such that emax = 1 or 2,
mpfr_asin may give an incorrect result on +1 and -1.
which should probably never occur in practical codes.
New in gsl-1.15:
** Added Tuomo Keskitalo's new ode branch ode-initval2 with a
gsl_odeiv2 prefix. This provides proper support for implicit
solvers. It is intended to be the new default for differential
equations. The existing gsl_odeiv routines will be retained for
binary compatibility but their interface will be deprecated.
** Added new gsl_integrate_cquad routines for robust integration of
difficult functions using the doubly-adaptive CQUAD algorithm
(Pedro Gonnet).
** Added error checking to CBLAS functions (Jose Luis Garcia Pallero)
** Added a new function gsl_integration_glfixed_point to return
ordered Gauss-Legendre points and weights contained within a
gsl_integration_glfixed_table [bug #32237].
** Added a new function gsl_interp_type_min_size to return the size of
an interpolation type.
** Added a function gsl_pow_uint(x,n) to compute x^n for unsigned
exponents (needed when n exceeds the range of signed integers).
** Added new routine gsl_linalg_complex_cholesky_invert to handle the
matrix inversion for complex Cholesky decompositions (Huan Wu).
** Added the functions gsl_vector_equal(x,y) and gsl_matrix_equal(x,y)
for testing equality of two vectors or matrices.
** Added function gsl_eigen_nonsymmv_params to control the balancing
transformation for eigenvector calculations. Balancing is now
turned off by default for gsl_eigen_nonsymmv.
** It is now possible to choose an alternative cblas library via
pkg-config using the GSL_CBLAS_LIB environment variable or
the pkg-config --define-variable option.
** The jacobi method gsl_eigen_jacobi now uses the norm of the
off-diagonal elements for its convergence criterion, as in
algorithm 8.4.3 of Golub and van Loan.
** The newton multiroot solvers now return an error when a singular
jacobian is detected.
** The interpolation functions now return NaN and when x is out of range,
instead of extrapolating.
** The gsl_multimin_fdfsolver multidimensional minimisers now return
GSL_ENOPROG immediately if the generated trial point does not
differ from the initial point (to machine precision), avoiding
unnecessary further iterations.
** Extended the range of gsl_sf_bessel_lnKnu_e by rescaling
intermediate results to avoid internal overflows [bug #31528].
** Improved the result of gsl_sf_atanint_e for large arguments by
adding the first order 1/x correction term. [bug #29562]
** Fixed the gsl_rng_ranlxs generators to enforce a maximum seed value
of 2^31-1. Larger seed values caused out of range values to be
returned.
** Fixed gsl_ran_chisq_pdf(x,nu) to return correct result of 1/2
instead of 0 when x=0 and nu=2, and +inf when x=0 and nu<2.
** Fixed gsl_pow_int(x,n) to avoid an infinite loop when n=INT_MIN due
to wrapping of signed integers.
** Fixed gsl_sf_hyperg_2F1(a,b,c,x) to avoid returning NaN for
arguments |a|>10. [bug #24812]
** Avoid spurious underflow return code in gsl_sf_beta_inc_e when
intermediate underflow does not affect the result. [bug #30933]
** Avoid segfault in Chebyshev series derivatives gsl_cheb_calc_deriv
for n=1. [bug #29139]
Changes in Mathomatic version 15.6.0:
------------------------------------
Many tweaks and corrections to simplification and polynomial operations were made.
Created m4 Mathomatic input file "tests/trig". Lists all trig and
hypertrig functions, allowing testing of their simplification
and manipulation.
Sped up polynomial operations to be another 30 times faster
in some cases. Finished and cleaned up the polynomial factoring
and division C code. Thanks again to Kingsley G. Morse Jr. for
showing me this needed to be done.
The "simplify quick" command was changed to not combine unlike
denominators, making it much more useful, doing better
simplification than any other simplify option sometimes.
The tally command now returns the ending total and sets it as the
current equation.
Fixed an old bug just discovered today where expressions like
(x - y)*(x^99 - y^99) were being factored into something huge
with the simplify and fraction commands, which are the only
commands that do polynomial factoring.
Improved coloring scheme: all prompt and normal text is now the
terminal emulator's default color for text (usually uncolored).
Expressions remain colored if color mode is enabled. Thanks to
Carl U. Grayser for the good idea.
Improved the fraction command by factoring polynomials first.
Specifying the "numerator" and "denominator" options together
will make the fraction command return with failure if the result
is not a fraction, otherwise the entire fraction is returned.
Changes in Mathomatic version 15.5.3:
------------------------------------
Simplify expressions with positive bases like 16^(x/2) and (2^m)^n by default;
previously only simplified these with the "simplify symbolic" command.
The exit status of Mathomatic now shows any errors when run with the
-e option. So if a command fails, it exits to the OS with the exit
status 1. Exit status is 0 if everything went OK. Also works without
the -e option, when files are specified on the shell command line.
An error will abort the script, returning you to the operating system
with an exit status of 1.
Changed makefile to allow installing m4 Mathomatic without installing
the documentation. Use "sudo make bininstall matho-rmath-install" to
install m4 Mathomatic executables and man pages.
Then "sudo make docinstall" installs all documentation.
The rmath man page math function and constant lists have been corrected
and the rmath man page has been added to the main user documentation.
Output of universal constants is now prettier when displaying. No
more i#, e#, and pi#, they are displayed as they are entered: i, e,
and pi. HTML mode displays the small Greek letter pi for pi.
The nintegrate command now works with complex numbers and trigonometry,
and does not change the current equation to the result.
Link the man page rmath.1 to matho.1 when installing, so that every
executable has a man page.
Added "numerator" and "denominator" options to the fraction command,
which returns only the numerator or denominator after making sure the
expression is a simple algebraic fraction.
Autocalc now deletes only the previous autocalc when autocalc is used.
It was deleting all autocalc results except for the current one every
time, preventing copying.
Improved simplification of expressions like (x + (2^(1/2)))^{3,4,5,6}.
It broke a while back when factor_times() constant factoring was
improved. The fix uses factor_times() less, preserving reduced surds.
Saving "plot_prefix" with the "set save" command was not escaping
semicolons, so they were disappearing from the prefix. Fixed now.
Changes in Mathomatic version 15.5.2:
------------------------------------
Renamed the "factorial" directory to "examples".
Fixed entering negative odd roots like (-32)^(1/3) to not approximate,
instead simplifying to -2*4^(1/3). So all surds are preserved, now.
Added man pages for the Mathomatic Symbolic Math Library functions.
Allow building a PDF book of all Mathomatic man pages.
Simplify command simplification sped up even more, by putting algebraic
fraction reduction in the right place and not overusing it.
Responsiveness has greatly improved for large expressions. Thanks go
to Kingsley G. Morse Jr. for help with this and for filing a bug report.
The simplify command functionality was improved. It was fixed to
not mess up with unwanted fractional coefficients.
Changes in Mathomatic version 15.5.1:
------------------------------------
Many minor cleanups and corrections were made.
Renamed Mathomatic User's Manual to Official Mathomatic User Guide.
Calculate command now outputs fewer newlines. Not so much blank space.
Allow equation-number-ranges on the plot command line. For example,
"plot all" works now, to plot all stored equations and expressions
at once, for easy comparison.
Changes in Mathomatic version 15.5.0:
------------------------------------
Fixed result of (constant % inf) to equal constant.
Restored explicitly linking with ncurses library when compiled
with readline, because Red Hat Linux wrongly requires this.
There is no way to know ahead of time whether this is needed, so
remove the "-lncurses" from the makefile if there is a problem
linking.
Upgraded set option "fractions_display_mode" to display fractions
as mixed fractions when possible, when set to mode 2. A mixed
fraction is possible when the numerator of a simple fraction is
greater than the denominator, like 9/4, which displays as (2+(1/4))
in mixed fraction display mode 2. Mode 1 is the default, which
functions as before, displaying 2.25 as the simple fraction 9/4.
To display mixed fractions only on command, just type "display mixed"
to display the current expression with mixed fractions output
that one time.
Autocalc (used when typing a numerical only expression at the main
prompt) now keeps the result until next time autocalc is used,
so that it can be acted on further by Mathomatic commands, if desired.
All previous autocalc results are erased every time autocalc is used.
This provides much better calculator functionality for Mathomatic
and improves ease-of-use.
Use HTML infinity symbol (∞) for infinities in HTML output mode.
Allow solid fraction bar display in HTML output mode by using "–".
Previously the ASCII dash character "-" was used, making a dashed line
that separated the numerator and denominator of fractions. Now the line
should be solid in HTML output mode.
Improved divide command for numerical division. Added mixed fractions
and cleaned up output.
Ported matho-primes to MS-Windows and included it in the Windows
version on my website: "http://mathomatic.org/winam2.zip".
The fraction command is now repeatable by preceding it with "repeat".
This repeatedly runs it until the smallest expression is achieved.
Simplification was sped up, especially with "simplify quick", therefore
differentiating and the Taylor command are faster.
Removed the requirement for the Unix "time" command with m4 Mathomatic.
Allow array variable refs like a[2] or a[1][2] when generating C code.
Just "set special []" to allow straight brackets in variable names.
Another ease-of-use enhancement was implemented, making it possible to
use "#equation-number" anywhere in any expression, it will insert the
expression at that equation number. This is an improvement that should
have been done long ago. However, don't expect it to work with the
plot command, "plot #1" does not work because the argument to plot is a
string and/or the current equation. For example, typing things like
"y=#1^2" is a convenient way to raise the expression in equation space
number 1 to the power of 2 and set it equal to y, or whatever you wish.
Changes in Mathomatic version 15.4.4:
------------------------------------
Many minor but obnoxious bugs were fixed.
Fixed result of constant modulo 0 (e.g. 9 % 0) and infinity modulo
constant (e.g. inf % 9) to be NaN.
Disabled shelling out and the edit command only in m4 Mathomatic.
The terminal hung when shelling out or editing with an m4 front-end.
Plotting still works and pagination is working now for m4 Mathomatic.
Cleaned up tests/quartic.in, it now works without m4 Mathomatic, and is
a single formula to solve most fourth degree polynomial equations.
Created a nice man page for rmath and matho (rmath.1).
Changes in Mathomatic version 15.4.3:
------------------------------------
Fixed negate priority to be the same as TIMES/DIVIDE like Maxima (yay!).
So now entering -x^2 is meaningful. Previously negate was the highest
priority (high precedence) operator. Entering -2^2 now results in -4
instead of 4, as in most other mathematics programs (except for pure
calculators like bc).
Flush standard output before reading a line of input from the user
when not using readline, so that the MinGW version works with mintty.
Added a new "for" command, for plugging in sequential values into a
variable in the current expression and displaying the results.
The syntax is the same as the sum and product commands.
Changes in Mathomatic version 15.4.1:
------------------------------------
Upgraded the plot command towards always giving gnuplot a proper plot command,
no matter what the user input is. The plot command now automatically renames the
variable in a single variable expression to the x variable, so plotting
will always succeed.
Removed Python script "misc/mp"; Couldn't get mpmath to work properly for
all input.
Improved results of the fraction command.
Now saving readline history in $HOME/mathomatic_history when compiled for CygWin.
Now additionally searching for "mathomatic.rc" in $HOME when compiled for CygWin.
Ported matho-pascal and matho-primes to double floats if USE_DOUBLES is defined,
for systems that don't support long double floats.
Changes in Mathomatic version 15.4.0:
------------------------------------
Added "compare approximate" command option, use of which is more likely to
result in a successful comparison. Runs the approximate command on
both expressions before comparing, if needed.
The variables command syntax was upgraded to be the same as the code command.
Added code to delete identities in the optimize command. When identical
equations were optimized, identities would result. These are now removed.
Fixed incorrect syntax in the menu files in menu directory.
Added "tests/quartic.in". At last, a working set of equations for calculating
the four solutions of any quartic equation, similar to "tests/cubic.in".
Fixed parser routine to give a helpful error message when a cursor or function key
string is encountered. Escape, carriage return, and form-feed are ignored now.
Changes in Mathomatic version 15.3.7:
------------------------------------
Fixed the modulus operator (%) to always evaluate to an integer when
both arguments are integer.
7921%14 was giving 11.000000000001, now gives exactly 11.
Equation number ranges for commands may include unallocated equation
spaces now, allowing entry of any reasonable range.
Changes in Mathomatic version 15.3.6:
------------------------------------
Many minor fixes for consistency and helpfulness were made.
Cleaned up "factor numbers" command for consistency in operation and to
work as documented.
Warn when substituting a non-integer expression into an integer variable.
Added m4/degrees.m4, this can be read into rmath with "rmath degrees.m4"
to use degree units instead of radians for trig functions.
"sudo make m4install-degrees" installs degree mode as the default for
matho and rmath by appending m4/degrees.m4 to m4/functions.m4.
Allow input of #equation-number as the LHS or RHS of any equation. It is
replaced with the expression or RHS at the specified equation-number.
Note that #equation-number is also the current equation selector, so entering
it as the LHS at the main prompt will function differently.
Simplify (integer % 1) and the like to 0. Generalized to instantly simplify
to 0 the following: (integer_expression % +/-unit_fraction).
Changes in Mathomatic version 15.3.4:
------------------------------------
Fixed an error reporting bug in the solve command.
There was the possibility of spewed space characters with improper input.
Added code so that solving for 0^2 or variable^2 will properly square both
sides of an equation. Solving for variable^2 will isolate the square root of
the largest expression containing that variable, and then square both sides of
the equation. Works for any power and variable with any equation with roots.
Changes in Mathomatic version 15.3.3:
------------------------------------
Fixed -e option to be more like entering what follows into the main prompt;
That is, the autosolve option is left on and errors do not abort.
"set finance" option now groups output with thousands' grouping characters
if the locale information indicates any. For example: 2,000,000.00
Changes in Mathomatic version 15.3.2:
------------------------------------
Added "help options" command which lists invocation options (like -h).
Entering "nan" now gives a warning, instead of an error,
so that expressions containing NaN can be read back in without aborting.
Added "-c count" option to matho-primes, optionally limiting the number
of lines of primes that are output to "count" lines.
Fixed an old, important bug in the Mathomatic solve routine, where solve was
failing on some easy to solve equations indeterminately, because of
incorrect infinite loop detection code. Solving should work perfectly now.
This problem was discovered today with the input: "a=a+b" "a" "b".
Changes in Mathomatic version 15.3.1:
------------------------------------
Improved the help command, allowing multiple help topics on the help
command line.
Improved upon "misc/roots.c", the automatic polynomial root finder.
Increased the maximum number of equation spaces from 100 to 200.
They do not consume memory unless they are used.
Solving things like 0=(x+1)^15+x for x exited the solve routine without grace.
This problem is now fixed for all solve requests that aborted with error.
When using the symbolic math library, the display command now outputs
all specified equation spaces in fraction format and returns the last
equation space listed as a result.
Before it was just a crippled list command with a little simplification
that didn't output anything.
Changes in Mathomatic version 15.3.0:
------------------------------------
Changed -u option to also echo line input, so that m4 Mathomatic is easier to use.
X-Windows icon for the Mathomatic entry within desktop menu systems.
The repeat command can now be shortened to 4 characters, like any other command.
Capitalized E, I, and PI are now no longer parsed as universal constants.
Entering E, I, or PI will now result in the general variables E, I, and PI,
unless "set no case" is previously entered.
This change undoes version 15.2.0 Mathematica compatibility, due to kind user feedback.
Entering e, i, or pi still gives the universal constants e#, i#, and pi#.
Removed "set negate_highest_precedence" option.
This was done for compatibility and so that less parentheses are displayed
within expressions. Polynomials should display very nicely now, powers
like "x^2", "y^3", and "x^y" are not parenthesized unless need be.
Added "list hexadecimal" command option, which displays expressions
exactly as stored internally in hexadecimal. No precision is lost,
this is because the floating point values are not converted to decimal.
Error reporting was improved.
Changes in Mathomatic version 15.2.2:
------------------------------------
Added "set plot_prefix" option, which allows custom plot functionality.
Changes in Mathomatic version 15.2.1:
------------------------------------
Added the -e option, which processes mathematical expressions and Mathomatic commands
instead of input files on the shell command line.
Improved results of solving for zero. Results should have reduced integer coefficients,
by factoring out the GCD of rational coefficients.
The Spreadsheet Library is designed to read and write Spreadsheet Documents.
As of version 0.6.0, only Microsoft Excel compatible spreadsheets are
supported. Spreadsheet is a combination/complete rewrite of the
Spreadsheet::Excel Library by Daniel J. Berger and the ParseExcel Library by
Hannes Wyss. Spreadsheet can read, write and modify Spreadsheet Documents.
Changes from version 3.0.0 to version 3.0.1:
- Bug fixes (see <http://www.mpfr.org/mpfr-3.0.0/#fixed> or ChangeLog file).
Note: The mpfr_subnormalize implementation up to MPFR 3.0.0 did not change
the flags. In particular, it did not follow the generic rule concerning
the inexact flag (and no special behavior was specified). The case of the
underflow flag was more a lack of specification.
This packages is for expandably converting numbers into binary, octal,
and hexadecimal. All constructs TeX accepts as an argument to its
\number primitive are valid.
Prompted by Stathis Kamperis.
Changes:
* New functions
+ mpc_set_dc, mpc_set_ldc, mpc_get_dc, mpc_get_ldc for
converting between mpc type variables and C variables of
type double _Complex or long double _Complex
+ mpc_sin_cos, computing simultaneously the sine and cosine
* Speed-ups
+ mpc_pow_si through binary exponentiation
+ mpc_pow_z when the exponent fits in a long
+ mpc_tan through the use of mpc_sin_cos
* Bug fixes
+ trigonometric functions: infinite loop due to overflow for large arguments
+ exp: close to infinite loop for argument close to 0
+ sqrt: close to infinite loop for argument close to 1
+ add_si: replaced macro by function, since the macro evaluated the same expression twice
* Logging feature for debugging
./configure --enable-logging
#include "mpc-log.h" instead of #include "mpc.h"
* Minimally required library versions: gmp 4.3.2, mpfr 2.4.2
* No need automake to build.
* clean up subst patterns, not to break shell script.
* more 32bit and 64bit patterns
* pass down prefered environments to build.
* DL_LIBS came from dlopen.buildlinnk3.mk, need to buildlink.
and sysutils/nautilus-sendto to use the new devel/glib2/schemas.mk logic to
properly recompile the GSettings database during install/deinstall.
Bump PKGREVISION for these packages.
(This lets evince work in my machine; it would crash on startup because
it would not find its schema. I suspect this also fixes all the other
applications mentioned in this change. And the inclusion of schemas.mk
also prevents these packages from causing side-effects on the system if
they happen to call glib-compile-schemas during their build.)
alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:

remove RESTRICTION, because COPYING file said GPL or LGPL, nothing for others.
PyEphem CHANGELOG
=================
Version 3.7.3.4 (2009 April 30)
-------------------------------
- Added a new ``next_pass()`` method to ``Observer`` that searches for
when a satellite next rises, culminates, and sets.
- Added a ``compute_pressure()`` method to ``Observer`` which computes
the standard atmospheric pressure at the observer's current elevation.
This function now gets called automatically on new ``city()`` objects
before they are returned to the user.
- Corrected the altitude of San Francisco as returned by ``city()``.
- Improved the copyright message so that two more authors are credited.
Version 3.7.3.3 (2008 October 3)
--------------------------------
- Added ``cmsI`` and ``cmsII`` attributes to ``Jupiter`` to provide the
central meridian longitude in both System I and System II.
- **Bugfix**: Saturn was returning the wrong values for its earthward
and sunward angle tilt.
Version 3.7.3.2 (2008 July 2)
-----------------------------
- **Bugfix**: the rising and setting functions, if called repeatedly,
would sometimes get hung up on a single answer which they would return
over and over again instead of progressing to the next rising or
setting. They should now always progress instead of getting stuck.
Version 3.7.3.1 (2008 July 1)
-----------------------------
- **Bugfix**: the rising and setting functions were attempting to
achieve such high precision that users sometimes found circumstances
under which they would not complete at all! They now stop and return
an answer once they are withing a half-second of the real time of
rising, transit, or setting, which solves the problem without damaging
the quality of the results when tested against the Naval Observatory.
- Upgraded to the libastro from XEphem 3.7.3.
Version 3.7.2.4 (2008 June 12)
------------------------------
- **Incompatible Change**: After feedback from users, I have changed
the ``Observer`` methods which find risings, settings, and transits,
so that they do not change their Observer's ``.date`` attribute. So
the sequence:
.. code-block:: python
r1 = boston.next_rising(mars)
r2 = boston.next_rising(mars)
now computes the same value twice! If you want a series of calls to
each begin when the other left off, you can use the ``start=``
parameter described in the next item:
.. code-block:: python
r1 = boston.next_rising(mars)
r2 = boston.next_rising(mars, start=r1)
- Added an optional ``start=`` argument to the rising, setting, and
transit ``Observer`` functions, that tells them from which date and
time to begin their search.
- **Bugfix**: Rewrote planetary moon routines so that moons of Mars,
Jupiter, Saturn, and Uranus now return appropriate data for years
1999-2020. (Each moon had been returning the unmodified position of
its planet, because I was unsure whether I could distribute the moon
data with PyEphem.)
- You can no longer create arbitrary attributes on an ``Observer``, to
prevent users from accidentially saying things like
``here.longitude`` or ``here.lon`` when they mean ``here.long``.
Create your own subclass of ``Observer`` if you need the power to
set your own attributes.
- The ephem module now provides a ``__version__`` symbol.
- Added test suite that tests planet and planet moon positions
against JPL ephemeris data (needs more work).
Version 3.7.2.3 (2008 January 8)
--------------------------------
- Three new classes ``Equatorial``, ``Ecliptic``, and ``Galactic``
allow coordinates to be transformed between the three systems
(ability to transform coordinates was requested by Aaron Parsons).
- Added constants for popular epochs ``B1900``, ``B1950``, and
``J2000``.
- Added named functions for every solstice and equinox (before, only
the vernal equinox could be asked for specifically).
- Product tests have been moved inside of the ``ephem`` module itself,
and can now be invoked simply by running:
.. code-block:: bash
$ python setup.py test
- **Bugfix**: ``Angle()`` can no longer be directly instantiated.
- **Bugfix**: San Francisco had the wrong coordinates in the cities
database (pointed out by Randolph Bentson).
Version 3.7.2.2 (2007 December 9)
---------------------------------
- The phases of the moon can now be determined through the functions
``next_new_moon()``, ``next_full_moon()``, ``previous_new_moon()``,
et cetera.
- Added a modest database of world cities; the ``city()`` function
returns a new Observer on each call:
.. code-block:: python
observer = ephem.city('Boston')
- Using the old ``rise``, ``set``, and ``transit`` attributes on
``Body`` objects now causes a deprecation warning.
- **Bugfix**: the last release of PyEphem omitted the constants
``meters_per_au``, ``earth_radius``, ``moon_radius``, and
``sun_radius``; the constant ``c`` (the speed of light) is also now
available.
Version 3.7.2.1 (2007 October 1)
--------------------------------
- Functions now exist to find equinoxes and solstices.
- Bodies now cleanly offer three different versions of their
position, rather than making the user remember obscure rules for
having each of these three values computed:
* Astrometric geocetric right ascension and declination
* Apparent geocentric right ascension and declination
* Apparent topocentric right ascension and declination
- Bodies can now find their next or previous times of transit,
anti-transit, rising, and setting.
- A ``localtime()`` function can convert PyEphem ``Date`` objects to
local time.
- Now ``ephem.angle`` instances can survive unary ``+`` and ``-``
without getting changed into plain floats.
- The ``elev`` Observer attribute has been renamed to ``elevation``.
- Observers now display useful information when printed.
- Added a much more extensive test suite, which, among other things,
now compares results with the United States Naval Observatory,
insisting upon arcsecond agreement.
- **Bugfix**: When a fixed body is repeatedly precessed to different
dates, its original position will no longer accumulate error.
Version 3.7.2a (2007 June)
--------------------------
- Upgraded to the libastro from XEphem 3.7.2.
- Should now compile under Windows!
- **Bugfix**: rewrote date-and-time parsing to avoid the use of
``sscanf()``, which was breaking under Windows and requiring the
insertion of a leading space to succeed.
- Improved the error returned when a date string cannot be parsed,
so that it now quotes the objectionable string (so you can tell
which of several date strings on the same line gave an error!).
3.0200 June 18, 2010
- Added skewness and kurtosis
- https://rt.cpan.org/Ticket/Display.html?id=58187
- Thanks to Shawn Laffan.
3.0102 June 15, 2010
- Add the $VERSION variable to Statistics::Descriptive::Sparse and
Statistics::Descriptive::Full. This was done to silence the CPAN indexer.
3.0101 June 15, 2010
- Moved the trimmed_mean caching test (that used the Benchmark.pm module)
to rejects/descr.t , because it kept failing.

CHANGES MADE TO MATHOMATIC 15.2.0 TO BRING IT UP TO THE NEXT VERSION:
All makefiles were improved. Library test/example program is renamed to "testmain".
Package maintainers please take note: support for the DESTDIR environment variable was
added to the makefiles; for proper operation when packaging version 15.2.1 or higher,
please remove any patches for missing DESTDIR support.
m4 Mathomatic should work now when included in the Mathomatic package (make m4install).
Thank you for packaging Mathomatic! If I did anything wrong, please let me know.
8/26/10 - Added the -e option, which processes mathematical expressions and Mathomatic commands
instead of input files on the shell command line. For example, entering
"mathomatic -eq 2+3" gives "answer = 5". This functionality has been requested
many times by Mathomatic command line users. A complete example:
CHANGES MADE TO MATHOMATIC 15.1.6 TO BRING IT UP TO THE NEXT VERSION:
Minor improvements were made to the user documentation.
8/22/10 - Removed "Complex number roots approximated" warning message, since this happens often.
Capitalized E, I, PI, and Pi are now accepted as the universal constants e, i, and pi,
without needing to enter "set no case". This allows Mathomatic to easily
accept Mathematica style expression input.
m4 Mathomatic now additionally accepts Mathematica style capitalized function input.
matho and rmath now display elapsed, CPU, and system times in seconds upon exit.
8/23/10 - Fixed #equation-number entry at the main prompt to always work and allow an expression
or equation following on the same line to be entered at that equation space.
For example: "#10 y=1/x" will work now;
previously only worked if equation space number 10 was previously allocated and used.
The way it works is: all equation spaces up to and including number 10 are allocated,
if not already allocated, upon entry of "#10".
Equations spaces are allocated with the memory allocator malloc(3).
CHANGES MADE TO MATHOMATIC 15.1.5 TO BRING IT UP TO THE NEXT VERSION:
7/26/10 - Disabled ncurses call for auto-color detection when CYGWIN is defined while
compiling the source code, due to a reported problem of readline failing with
ncurses in Cygwin.
7/28/10 - Disabled readline history save file for the Cygwin port,
because it is a filename that starts with a period.
7/31/10 - Added "set fractions_display" option, to allow disabling the automatic conversion of
fractions like .5 to 1/2 for display.
Developer requested and useful in the symbolic math library,
when numerical fraction output isn't wanted.
8/01/10 - Fixed a memory leak when ignoring the output string in the symbolic math library.
8/04/10 - Preserve overflowed powers like 2^2222 rather than aborting with an error message.
Allow simplification of math like 2*2^2222 and 2/2^2222.
8/08/10 - matho-primes runs twice as fast with the -ffast-math gcc compilation option,
which is now enabled by default. Don't try -ffast-math with the main Mathomatic
program though, because then Mathomatic won't work properly.
CHANGES MADE TO MATHOMATIC 15.1.4 TO BRING IT UP TO THE NEXT VERSION:
Many minor tweaks and improvements.
7/03/10 - Makefiles and compile scripts were corrected and enhanced
per http://www.gnu.org/prep/standards/
7/06/10 - Changed all "#if true" and "#if false" conditional commenting to "#if 1" and "#if 0"
in the C source code, thanks to Min Sik Kim of NetBSD pkgsrc.
CHANGES MADE TO MATHOMATIC 15.1.3 TO BRING IT UP TO THE NEXT VERSION:
All of the Unix man pages and user manuals for Mathomatic were fixed.
The compare and "solve verify" commands now simplify more thoroughly with "repeat simplify"
for better expression equality determination.
6/17/10 - Greatly improved file operation error reporting by using the perror(3) function.
6/18/10 - Fixed categories in "icons/mathomatic.desktop";
Mathomatic now goes under valid categories, mainly Education.
CHANGES MADE TO MATHOMATIC 15.1.2 TO BRING IT UP TO THE NEXT VERSION:
6/6/10 - I made mistakes in the improvement to the simplify command of version 15.1.2,
the original working simplify logic of version 15.1.1 is now restored, sorry.
CHANGES MADE TO MATHOMATIC 15.1.1 TO BRING IT UP TO THE NEXT VERSION:
A general cleanup was done.
A small improvement was made to the final result of the simplify and fraction commands.
Showing intermediate results in the calculate, sum, and product commands is now done with "set debug 1".
5/28/10 - Added "tests/collatz.in", the Collatz conjecture as an automatically computable equation.
CHANGES MADE TO MATHOMATIC 15.1.0 TO BRING IT UP TO THE NEXT VERSION:
Code and documentation cleanup.
5/21/10 - Added "primes/matho-sum", a utility that sums its command line arguments or standard input.
Use "matho-primes 0 2000000 | matho-sum" to find the sum of all primes less than 2,000,000.
Solves Project Euler problem #10: http://projecteuler.net/index.php?section=problems&id=10
5/23/10 - Primes (') are allowed in variable names now, if not using the symbolic math library, so that the
derivative, integrate, and nintegrate commands can change the dependent variable to y', y'', etc.
This can be turned on in the symbolic math library by the command "set special_variable_characters='".
Non-alphanumeric characters in variable names are now converted to underline characters (_)
when exporting to a programming language or to a different program.
CHANGES MADE TO MATHOMATIC 15.0.8 TO BRING IT UP TO THE NEXT VERSION:
5/10/10 - Added "help constants" command.
5/11/10 - Integer variables are now specified by using a variable name that starts with "integer",
like "integer1", "integer_x", etc. Currently only the modulus operator "%" checks
for integer variables, to help with simplification.
5/12/10 - Corrected the output string type of the symbolic math library API. It was erroneously declared
as type "const", possibly causing a memory leak.
5/13/10 - Moved and adapted "makefile.lib" to "lib/makefile", so the symbolic math library build is isolated.
Previously "make clean" was required between different builds. All makefiles require GNU make now.
CHANGES MADE TO MATHOMATIC 15.0.7 TO BRING IT UP TO THE NEXT VERSION:
4/26/10 - Allow "make pdf" to generate PDF documentation from the HTML documentation with htmldoc.
Please read the comments in the makefile for all available options.
4/29/10 - For every makefile, CFLAGS has been modified to include OPTFLAGS as required by the Fedora Linux
build system, and OPTFLAGS defaults to the optional gcc specific flags like optimization.
In the symbolic math library, made available the equation number of the result of calling the API,
if also stored in an equation space. The result equation number is stored in the global "result_en".
Useful if you want to know where the result was stored, to act on it with further commands.
CHANGES MADE TO MATHOMATIC 15.0.6 TO BRING IT UP TO THE NEXT VERSION:
Corrections and improvements to the documentation were made.
4/3/10 - Vastly improved the "factor number" user interface, now factors integer expressions like 2^32-1.
"factor number" is disabled in library mode.
4/13/10 - The real and imaginary commands no longer fail when the expression is not complex,
just a warning is given.
4/14/10 - Changed normal display of "-1*" to "-", for prettier 2D expression output,
so things like "-a" display properly, not as "-1*a".
CHANGES MADE TO MATHOMATIC 15.0.5:
1/28/10 - Added a Python utility called "primorial" to the Prime Number Tools install
that multiplies together the results of matho-primes, displaying the primorials
of the integers given on the command line.
3/18/10 - Changed author email address to "gesslein@linux.com".
3/23/10 - Catch SIGHUP and SIGTERM signals for proper termination of the Mathomatic program;
readline was messing up when Mathomatic was terminated by closing the shell window.
The plot command now always plots expressions with grid marks displayed for reference.
CHANGES MADE TO MATHOMATIC 15.0.4:
1/21/10 - In the makefile, changed the HTML man page generator back to rman because
groff HTML output looks really bad and rman allows linking to other man pages.
groff is no longer used.
1/24/10 - Fixed "make m4install", the installed rmath and matho programs weren't working.
1/27/10 - Added GNU LGPL license notices to every C source file with a copyright notice,
for proper protections.
CHANGES MADE TO MATHOMATIC 15.0.3:
1/9/10 - Fixed a problem only in the version 15.0.3 makefile, where it didn't respect
the CC environment variable set by the user, instead it always used "gcc"
as the C compiler.
CHANGES MADE TO MATHOMATIC 15.0.2:
12/27/09 - Moved get_screen_size() from main.c to am.c because it is used in the library when
compile-time options UNIX or CYGWIN are defined.
Thanks to Cygwin port maintainer Reini Urban for noticing and fixing this problem.
Defining UNIX or CYGWIN in library mode is not recommended.
12/31/09 - Added code to allow any command to be preceded by "repeat", which sets the
repeat flag for the following command. Most commands ignore the repeat flag.
1/1/10 - Ported divide and roots commands to be repeatable. Also repeatable are the
calculate and eliminate commands.
1/2/10 - Allow Taylor series computation even if the specified differentiation variable
is not found in the expression, giving a warning.
Ported simplify command to be a repeatable full simplify; that is, typing
"repeat simplify" repeatedly runs the simplify command until the result stabilizes
to the smallest size expression.
1/7/10 - Thanks to pretty C code submitted by Simon Geard,
the code and variables commands have been made much more readable.
1/8/10 - Made Mathomatic easier to compile under Solaris, thanks to Michael Pogue of Sun.
Fixed failure to compile under BSD Unix when compiling with readline support.
CHANGES MADE TO MATHOMATIC 15.0.1:
12/19/09 - The last few versions fix the ugliness caused by the GCD factoring change made on 6/22/09.
Today's change factors out the numerical GCD of rational coefficients as needed to simplify.
Most simplification results should be beautiful and the simplest possible again now,
without the misleading observed magnitude caused by always factoring out the GCD,
which was why the change of 6/22/09 was made.
CHANGES MADE TO MATHOMATIC 15.0.0:
12/12/09 - Fixed a problem with the -q (quiet mode) option being ignored if the session options
were ever saved with the "set save" command.
12/13/09 - Added code to allow Mathomatic output to be redirected by default.
Fixed the derivative command to be successful even when the result is 0,
when compiled as a library.
12/14/09 - Added ability to log symbolic math library results, and made command behavior
more consistent in the library by always returning the final result string.
12/16/09 - The factor command now factors more by factoring out the GCD of rational coefficients.
CHANGES MADE TO MATHOMATIC 14.6.3 TO BRING IT UP TO 15.0.0:
Cleanup and more bug fixes.
11/26/09 - Added detection of the terminal's ANSI color availability, when readline is enabled.
11/28/09 - Added detection of divide by zero and NaN when using the "solve verify" command,
for more correct results.
Solving now factors out the GCD of rational coefficients, for improved results.
The fixes today are from errors solving equations like (2*x/(x - 3)) + 3 = 6/(x - 3)
11/29/09 - Disallow the variable named "nan". NaN cannot be directly entered into Mathomatic.
11/30/09 - Added shell scripts "t" and "tests/t" to easily test Mathomatic by typing "./t".
12/2/09 - The fraction command now factors out the GCD of rational coefficients like the
solve command does, so that coefficients in algebraic fractions become integers.
The GCD verifying routine was perfected by making it very strict, like it should be.

API Changes
Returning dictionaries
Several of the algorithms and the degree() method now return dictionaries keyed
by node instead of lists. In some cases there was a with_labels keyword which is
no longer necessary. For example,
>>> G=nx.Graph()
>>> G.add_edge('a','b')
>>> G.degree() # returns dictionary of degree keyed by node
{'a': 1, 'b': 1}
Asking for the degree of a single node still returns a single number
>>> G.degree('a')
1
The following now return dictionaries by default (instead of lists) and the
with_labels keyword has been removed:
* Graph.degree(), MultiGraph.degree(), DiGraph.degree(),
DiGraph.in_degree(), DiGraph.out_degree(), MultiDiGraph.degree(),
MultiDiGraph.in_degree(), MultiDiGraph.out_degree().
* clustering(), triangles()
* node_clique_number(), number_of_cliques(), cliques_containing_node()
* eccentricity()
The following now return dictionaries by default (instead of lists)
* pagerank()
* hits()
Adding nodes
add_nodes_from now accepts (node,attrdict) two-tuples
>>> G=nx.Graph()
>>> G.add_nodes_from([(1,{'color':'red'})])
Examples
* Mayvi2 drawing
* Blockmodel
* Sampson?s monastery
* Ego graph
Bug fixes
* Support graph attributes with union, intersection, and other graph
operations
* Improve subgraph speed (and related algorithms such as
connected_components_subgraphs())
* Handle multigraphs in more operators (e.g. union)
* Handle double-quoted labels with pydot
* Normalize betweeness_centrality for undirected graphs correctly

V 4.9.5 - Dec 10, 2007 Updated software license, allowing distribution
of modified source code.
The actual library source code is identical to
version 4.9.2 (except the obvious library version
identifier, and Digital Mars #ifdef).
Added support for the Digital Mars Compiler.
Added build script for Intel Linux Compiler.
V 4.9.5a - Feb 21, 2010 Updated authors email address.
Note that there are no changes to the library
source code - so the library will still identify
itself as "4.9.5".
Added Makefile for Microsoft Visual Studio 2005.
Added another Makefile for MAC OSX (for 10.6).
Changes in muParser 1.32

Changes in muParser 1.31cp
--------------------------
Changes:
* Archive structure changed
* C# wrapper added
* Fixed issued that prevented compiling with VS2010 Beta2
Contributed by Kamel Derouiche via PR pkg/43741
Changes in this version:
It works with Borland Builder version 6, 8;
Microsoft Visual C++ 6,7,8; Open Watcom 1.7a;
Gnu version 3, 4 and Intel for Windows & Linux compilers 9, 10.
Options and work-arounds for older compilers are being removed.
You can enter values from an integer array with statements like
Matrix A(3,2); int a[] = { 11,12,21,22,31,33 }; A << a;
There is a new matrix type SquareMatrix. You can use this where
you know a matrix is square. The only place where the information
that a matrix is used is in the Kronecker product KP(A,B).
If A is band and B is any square matrix type (i.e. type SquareMatrix
or band, triangular, symmetric or diagonal) the result is band.
If B is type Matrix then the result is of type Matrix.
Apart from this it may be worth using the SquareMatrix type to
improve readability of a program and to make sure that a matrix
that is intended to be square really is square.
There is a new routine for carrying out cross products of
ColumnVectors or RowVectors of length 3 and new routines for
updating a triangular matrix derived from a Cholesky decomposition.
Interfacing with old C functions involving one and two
dimensional arrays is simplified.
Additional QR functions, extend_orthogonal function.
Lower-case versions of functions.
You can use the manipulators scientific and fixed in the matrix
output expressions.

Packaged by Marko Schuetz for pkgsrc-wip.
MPC is a C library for the arithmetic of complex numbers with
arbitrarily high precision and correct rounding of the result.
It is built upon and follows the same principles as MPFR.
changes:
-new compressor called Blosc (speed-up)
-A new `tables.Expr` module (based on Numexpr) that allows to do
persistent, on-disk computations on many algebraic operations.
-Support for HDF5 hard links, soft links and automatic external links
-Suport for 'fancy' indexing
-bugfixes
Contributed by Stathis Kamperis on IRC.
Changes from versions 2.4.* to version 3.0.0:
- The "boudin aux pommes" release.
- MPFR 3.0.0 is binary incompatible with previous versions but (almost)
API compatible. More precisely the obsolete functions mpfr_random
and mpfr_random2 have been removed, the meaning of the return type
of the function mpfr_get_f has changed, and the return type of the
function mpfr_get_z is now int instead of void. In practice, this
should not break any existing code.
- MPFR is now distributed under the GNU Lesser General Public License
version 3 or later (LGPL v3+).
- Rounding modes GMP_RNDx are now MPFR_RNDx (GMP_RNDx kept for
compatibility).
- A new rounding mode (MPFR_RNDA) is available to round away from zero.
- The rounding mode type is now mpfr_rnd_t (as in previous versions,
both mpfr_rnd_t and mp_rnd_t are accepted, but mp_rnd_t may be
removed in the future).
- The precision type is now mpfr_prec_t (as in previous versions, both
mpfr_prec_t and mp_prec_t are accepted, but mp_prec_t may be removed
in the future) and it is now signed (it was unsigned in MPFR 2.*, but
this was not documented). In practice, this change should not affect
existing code that assumed nothing on the precision type.
- MPFR now has its own exponent type mpfr_exp_t, which is currently
the same as GMP's mp_exp_t.
- Functions mpfr_random and mpfr_random2 have been removed.
- mpfr_get_f and mpfr_get_z now return a ternary value.
- mpfr_strtofr now accepts bases from 37 to 62.
- mpfr_custom_get_mantissa was renamed to mpfr_custom_get_significand
(mpfr_custom_get_mantissa is still available via a #define).
- Functions mpfr_get_si, mpfr_get_ui, mpfr_get_sj, mpfr_get_uj,
mpfr_get_z and mpfr_get_z_2exp no longer have cases with undefined
behavior; in these cases, the behavior is now specified, and in
particular, the erange flag is set.
- New functions mpfr_buildopt_tls_p and mpfr_buildopt_decimal_p giving
information about options used at MPFR build time.
- New function mpfr_regular_p.
- New function mpfr_set_zero.
- New function mpfr_digamma.
- New function mpfr_ai (incomplete, experimental).
- New functions mpfr_set_flt and mpfr_get_flt to convert from/to the
float type.
- New function mpfr_urandom.
- New function mpfr_set_z_2exp (companion to mpfr_get_z_2exp, which
was renamed from mpfr_get_z_exp in previous versions).
- Speed improvement for large operands in the trigonometric functions
(mpfr_sin, mpfr_cos, mpfr_tan, mpfr_sin_cos): speedup of about 2.5
for 10^5 digits, of about 5 for 10^6 digits.
- Speed improvement for large operands of the inverse trigonometric
functions (arcsin, arccos, arctan): about 2 for 10^3 digits, up to
2.7 for 10^6 digits.
- Some documentation files are installed in $docdir.
- The detection of a GMP build directory (more precisely, the internal
header files of GMP) was previously done separately from the use of
the --with-gmp-build configure option. This was not consistent with
the documentation and with other parts of the configure script. So,
as of MPFR 3.0.0, the internal header files of GMP are now used if
and only if the --with-gmp-build configure option is given.
- The configure script recognizes some extra "long double" formats
(double big endian, double little endian, double-double big endian).
- MPFR manual: added "API Compatibility" section.
- Test coverage: 97.1% lines of code.
- Bug fixes.
The following suffixes for variables and constraints were
implemented in the MathProg language:
.lb (lower bound),
.ub (upper bound),
.status (status in the solution),
.val (primal value), and
.dual (dual value).
Now the MathProg language allows comment records (marked by
'#' in the very first position) in CSV data files read with the
table statements. Note that the comment records may appear only
in the beginning of a CSV data file.
The API routine glp_cpp to solve the Critical Path Problem was
added and documented.
Notable changes (compared to version 1.0.9) include:
- New domains and packages: VectorSpaceBasis domain,
DirichletRing domain, 3D graphic output in Wavefront .obj format,
specialized machine precision numeric vectors and matrices (faster
then general vectors and matrices), Html output.
- Support Clifford algebras corresponding to non-diagonal matrix,
added new operations.
- 'normalize' now tries to simplify logarithms of algebraic constants.
- New functions: Fresnel integrals, carmichaelLambda.
- Speed improvements: several polynomial operations are faster,
faster multiplication in Ore algebras, faster computation of
strong generating set for permutation groups, faster coercions.
- Several improvements to the guessing package (in particular new
option Somos for restricting attention to Somos-like
sequences
Bug fixes, in particular:
- FriCAS can now compute multiplicative inverse of a power series
with constant term not equal to 1.
- Fixed a problem with passing interpreter functions to algebra.
- Two bugs causing crashes in HyperDoc interface are fixed.
- FriCAS now ignores sign when deciding if number is prime.
- A failing coercion that used to crash FriCAS is now detected.
- 'has' test sometimes gave wrong result.
- Plotting fixes.
* R CMD INSTALL checks if dependent packages are available early on
* in the installation of source packages, thereby giving clearer
error messages.
* R CMD INSTALL --build now names the file in the format used
for Mac OS X binary files on that platform.
* BIC() in package stats4 now also works with multiple fitted models,
analogously to AIC().
* Use of file extension .C for C++ code in packages is now
deprecated: it has caused problems for some 'make's on
case-insensitive file systems (although it currently works
with the recommended toolkits).
* The C function mkCharLenCE now no longer reads past 'len' bytes
(unlikely to be a problem except in user code).
* On systems without any default LD_LIBRARY_PATH (not even
/usr/local/lib), [DY]LIB_LIBRARY_PATH is now set without a trailing colon.
* More efficient utf8ToInt() on long multi-byte strings with
many multi-byte characters.
* aggregate.ts() gave platform-depedent results due to rounding
error for ndeltat != 1.
* package.skeleton() sometimes failed to fix filenames for .R or
.Rd files to start with an alphanumeric.
(missed those and *emacs* the first time round because they pull
in their png dependencies via default-on options; they were included
in the test bulk build though)
SciPy 0.7.2 is a bug-fix release with no new features compared to 0.7.1. The
only change is that all C sources from Cython code have been regenerated with
Cython 0.12.1. This fixes the incompatibility between binaries of SciPy 0.7.1
and NumPy 1.4.
SciPy 0.7.1 is a bug-fix release with no new features compared to 0.7.0.
