The octave-forge project contains functions for Octave which are not in
the main distribution. While the main Octave distribution is
conservative about accepting new functions and changes, octave-forge is
very open. As a result, be prepared for some lower quality code and
more rapidly changing interfaces to the functions in octave-forge.
notable changes besides bugfixes are:
** Multifit routines now handle iterations where |f| is already
minimised to zero, without division by zero.
** Numerical derivatives should now be calculated using the
gsl_deriv_forward, gsl_deriv_central and gsl_deriv_backward functions,
which accept a step-size argument in addition to the position x. The
original gsl_diff functions (without the step-size) are deprecated.
** The tridiagonal matrix solvers gsl_linalg_solve_symm_tridiag,
gsl_linalg_solve_tridiag, gsl_linalg_solve_symm_cyc_tridiag,
gsl_linalg_solve_cyc_tridiag now use the GSL_ERROR macro to report
errors, instead of simply returning an error code. The arguments to
these functions must now use exact lengths with no additional
elements. For cyclic systems all vectors must be of length N, for
tridiagonal systems the offdiagonal elements must be of length N-1.
** The singular value decomposition routines gsl_linalg_SV_decomp and
gsl_linalg_SV_decomp_mod now handle the SVD of a column vector (N=1,
arbitrary M), which can occur in linear fitting.
** Added Stefan-Boltzmann constant and Thomson cross section to
physical constants
Changes:
"factor number" command now accepts more than one integer.
Added file "mathomatic.ico".
Added temporary fix for 64 bit longs.
Added file "VERSION" which contains the version number of Mathomatic.
"makefile" modified.
Renamed "lgpl.txt" to "LICENSE.txt".
"make install" now installs all HTML files in "/usr/local/doc/mathomatic".
Added compile-time define "TIMEOUT_SECONDS".
Useful for limiting the amount of time Mathomatic can run as a CGI.
LibTomMath provides highly optimized and portable routines for a
vast majority of integer based number theoretic applications
(including public key cryptography). LibTomMath is not a cryptographic
toolkit itself but it can be used to write one [Used in LibTomCrypt
for RSA, DH and ECC public key routines].
Changes:
Proper exit after error reading files on the command line.
Added code to preserve roots of integers, if the result is irrational.
Fixed "calculate >filename".
Made "+/-2^.5" work as expected.
Code cleanup.
Full simplify added for every loop of taylor command.
Removed "replace temp" option, so that the "temp" variable can be renamed.

Improved solving. y=(x+1/x)^3 solves both ways, now.
Full simplify after every loop in derivative command added.
Move derivative and taylor commands to "diff.c".
Added "-m" option to Mathomatic (memory size multiplier).
It sets the size of equation spaces at run time.
important changes:
- Ports of Numeric functions
A bunch of Numeric functions were ported to numarray in the new
libnumeric module. To get these import from numarray.numeric. Most
notable among these are put, putmask, take, argmin, and argmax. Also
added were sort, argsort, concatenate, repeat and resize. These are
independent ports/implementations in C done for the purpose of best
Numeric compatibility and small array performance. The numarray
versions, which handle additional cases, still exist and are the
default in numarray proper.
- Faster matrix multiply
The setup for numarray's matrix multiply was moved into C-code. This
makes it faster for small matrices.
- bug fixes
For a complete list of changes see:
http://sourceforge.net/project/shownotes.php?release_id=250453
# XXX: following comment still true for buildlink3?
# R does ugly things in the configure to get the default list of arguments
# for linking Fortran, which exposes the buildlink2 tricks so clean up
# afterwards
Changes:
Renamed the Mathomatic executable to "mathomatic".
Add inverse Laplace transform. Usage: laplace inverse x
Fixed bug in solving for zero, which occurred when there were no
variables in the divisor.
Some improvement in solve routine.
This only worked with gnumeric-1.0.x, and depends on gnome1 structures.
gnumeric is at 1.2.x now, uses gnome2 and comes with an own plotting
package.
Should fix PR pkg/26009 by MLH.
This release fixes a bug related to post incrementing, some regression failures related to compiling under cygwin, and a number of gcc compiler warnings.
Changes:
Slight improvement to integrate and laplace commands.
Integrate/laplace x on (a+x)/(b+c) works now.
Added more examples to the documentation (am.htm).
2 to 10 times speedup for simplify command by fixing polynomial factoring.
The primary purpose of this release is to correct problems on big-endian
64 bit platforms. It also introduces some test code to verify that the
functions and constants work properly.
Changes since 11.2:
Doubled the default amount of memory consumption to 11 megabytes.
This allows equations twice as large.
Fixed bug factoring infinity.
Slight improvement to "integrate" command.
Trap window resize signal and set number of screen columns and rows.
Code cleanup.
Fixed factoring of constants in factor command.
Added "laplace" command.
Allow "#" as a comment, as long as it is not immediately followed by
a number.
Enabled shelling out for all versions with the "!" command.
Improvement and speedup for poly_gcd() and poly2_gcd().
Slight improvement in polynomial factoring made by deleting 1 line of code.
Use getopt(3) to parse command line options.
Made "-c" and "-h" options work together. If both are specified,
work in HTML mono mode.
CHANGES IN R VERSION 1.9.1
NEW FEATURES
o as.Date() now has a method for "POSIXlt" objects.
o mean() has a method for "difftime" objects and so summary()
works for such objects.
o legend() has a new argument 'pt.cex'.
o plot.ts() has more arguments, particularly 'yax.flip'.
o heatmap() has a new 'keep.dendro' argument.
o The default barplot method now handles vectors and 1-d arrays
(e.g., obtained by table()) the same, and uses grey instead of
heat color palettes in these cases. (Also fixes PR#6776.)
o nls() now looks for variables and functions in its formula in
the environment of the formula before the search path, in the
same way lm() etc look for variables in their formulae.
DEPRECATED & DEFUNCT
o Support for non-IEEE-754 arithmetic (which has been untested
for some time) will be removed in the next full release.
o Direct use of R INSTALL|REMOVE|BATCH|COMPILE|SHLIB is
deprecated: use R CMD instead.
o The gnome/GNOME graphics device is deprecated and will be
removed in the next full release.
Plus Bug Fixes.
Changes since 11.1c:
Moved notification of polynomial factoring success to debug level 1 or higher.
Removed "NO_COMPLEX_ROOTS" compile-time define option.
I am thinking of making this a run-time option.
Increased security of "SECURE" compile-time define.
Absolutely no file operations are allowed or linked in.
Added check for terminal with isatty().
This allows better piping into Mathomatic.
Split up change-log ("changes.txt" and "changes_old.txt").
Changed "x!" to mean gamma(x+1) for Laplace transforms.
Fixed parsing of things like "2e#", which failed before,
thinking it was scientific notation.
Wrote "primes/twin.c", to find twin primes.
Added "help usage" command.
Allow output of "help" command to be redirected to a file.
Fixed parsing of variable names (like "pig", which didn't work right).
Added "integrate" command.
Fixed "derivative" command.
Code cleanup.
Fixed "taylor" command.
The step from 1.0.12 to 1.2.12 is too large to mention all changes.
pkgsrc issues:
-use gnome2
-add python support (python23 provides a shared lib)
-XXX I've enabled libgda/gnomedb, this seems to be completelely
non-functional to me, but perhaps it is just my setup...
Changes since 11.1:
Added Java code generation (usage: "code java").
Added "list export" option, to display equations in exportable format.
They can be cut-and-pasted to another math program with this option.
Added a blank line after every equation listed with the "list" and
"code" commands. Looks better.
Made "MAX_VAR_LEN" completely flexible (can be set to any value; set to 80).
Improved factoring of polynomials with repeated factors by trying to
differentiate with respect to every variable.
Changes:
- Fixed "makefile" to be completely portable.
No longer requires GNU make.
- Simplified some code.
- Converted token_type.kind to enum type for better type checking.
- Removed all "unsigned" variables and type casts.
- Simplified "simplify" command code. Some speed up.
- Moved "*.in" and "fix*" to directory "tests".
- Implemented long variable names (up to 40 characters).
building even though it uses INSTALL_DATA on them so set SHAREMODE=644
rather than have to patch an ever increasing number of files.
Idea from Julio M. Merino Vidal.
Changes:
- Removed calc() fraction code for accuracy because of fraction slack
that was implemented in version 10.9c.
- Solve increase power function wasn't working with odd number roots.
Fixed. Appears to be another gcc optimizer bug.
- Improved simplify command.
- Tweaked factor_constants().
- Some changes to "makefile" for "readline" support.
"GNU make" or "gmake" required now.
- Fixed solving of "x^(1/99)=x".
- Fixed readline bug.
Changes:
- Changed unfactoring to improve simplification (again). This was a
bug fix (first one in a long time).
- Restored "epsilon" to original value in version 10.9b. Required
for factoring large polynomials.
- Changed factor_times() to preserve divides. This improved the
"unfactor" command.
- Added polynomial factoring to the very beginning of "simplify"
command. This is necessary in case you "unfactor" a complicated
equation, then "simplify".
USER-VISIBLE CHANGES
o Underscore '_' is now allowed in syntactically valid names, and
make.names() no longer changes underscores. Very old code
that makes use of underscore for assignment may now give
confusing error messages.
o Package 'base' has been split into packages 'base', 'graphics',
'stats' and 'utils'. All four are loaded in a default
installation, but the separation allows a 'lean and mean'
version of R to be used for tasks such as building indices.
Packages ctest, eda, modreg, mva, nls, stepfun and ts have been
merged into stats, and lqs has been returned to MASS. In all
cases a stub has been left that will issue a warning and ensure
that the appropriate new home is loaded. All the time series
datasets have been moved to package stats. Sweave has been
moved to utils.
Package mle has been moved to stats4 which will become the
central place for statistical S4 classes and methods
distributed with base R. Package mle remains as a stub.
Users may notice that code in .Rprofile is run with only the
new base loaded and so functions may now not be found. For
example, ps.options(horizontal = TRUE) should be preceded by
library(graphics) or called as graphics::ps.options or,
better, set as a hook -- see ?setHook.
o There has been a concerted effort to speed up the startup of
an R session: it now takes about 2/3rds of the time of 1.8.1.
o A warning is issued at startup in a UTF-8 locale, as currently R
only supports single-byte encodings.
plus many new features and bug fixes.
Changes:
- Removed some simplification optimizations in favor of correctness
and simpler code. Minor slowdown.
- Doubled "MAX_COMPARE_TERMS".
- Simplify order poly_div then smart_div reversed.
- Kludge for size checking in poly_div removed.
- Broke "am.in". Edited.
- Added "simplify poly" option to do poly_div first.
Changes:
- Fixed HTML mode "screen_rows" and "screen_columns" to be unlimited.
- Allow square brackets ([]) as parentheses and optimized parser.
- Simplification was improved.
Changes are bug-fixes mostly, but also synchronizes bundled GD
with GD 2.0.22 and updates PCRE to version 4.5. Several NetBSD
patches were integrated too, so future pkgsrc updates would
be even more smooth.
Full list of changes since PHP 4.3.4 is available at:
http://www.php.net/ChangeLog-4.php#4.3.6http://www.php.net/ChangeLog-4.php#4.3.5
Changes since 10.9b:
- Removed more MS-DOS specific code; functionality improved.
- Implemented what I call "fraction slack". This perfects float to
fraction conversion, and now Mathomatic doesn't rely on perfect
floating point routines. "-O" option added to CFLAGS in file
"makefile" (we can do this now).
- Changed modf() to fmod() where possible.
- Accuracy increased one more digit by reducing the "epsilon" variable.
- Cleaned up "makefile".
- Took a step towards internationalization with gettext(3) by
calling _() for all English strings. Everything ported except for
the "help" command.
- Commented out some unfactoring code that wasn't helpful and took out
the "pause" command from "all.in" for easier testing.
- Rearranged "simplify" command to simplify better.
- Removed some more unfactoring code and made simplification much
better. Go figure. Perfection has been achieved.
- Added "unfactor fully" option.
- Added "make test" to fully test Mathomatic after compilation.
- Removed masking of 8th bit in all Mathomatic input.
- Updated primes program with a nice user interface.
* Version for GNOME 2.6 (FINAL) call for tarballs. Includes:
- new locales for pa, en_GB, bg and ga.
- localized online user documentation from the Sun translation team.
for de, es, fr, it, ja, ko, sv, zh_CN, zh_HK and zh_TW.
Packaged by Bruce J.A. Nourish, and slightly modified by me.
Mathomatic is an automatic algebraic manipulator that is self-testing
and strictly follows the rules of algebra.
Mathomatic is an interpreter that can:
- Solve, simplify, and compare algebraic equations.
- Combine simultaneous equations.
- Perform basic calculus operations.
- Generate the sensitivity formula for one or more variables in an
equation.
- Act like a double precision floating point programmable calculator.
- Perform complex number and polynomial arithmetic.
- Compute the Greatest Common Divisor of numbers or polynomials.
- Generate "C" code from equations.
explicitly unset NeedFunctionPrototypes, which can no longer safely be done in recent
X11 sources (as _Xconst is only defined if this is set, yet is used everywhere).
by moving the inclusion of buildlink3.mk files outside of the protected
region. This bug would be seen by users that have set PREFER_PKGSRC
or PREFER_NATIVE to non-default values.
BUILDLINK_PACKAGES should be ordered so that for any package in the
list, that package doesn't depend on any packages to the left of it
in the list. This ordering property is used to check for builtin
packages in the correct order. The problem was that including a
buildlink3.mk file for <pkg> correctly ensured that <pkg> was removed
from BUILDLINK_PACKAGES and appended to the end. However, since the
inclusion of any other buildlink3.mk files within that buildlink3.mk
was in a region that was protected against multiple inclusion, those
dependencies weren't also moved to the end of BUILDLINK_PACKAGES.
Many, many, many additions, bug fixes, and improvements since the last
packaged version. Too many to even summarize here. Please refer to the
change log in the distfile or on the homepage.
Changes sinec 5.1.12:
* [ES] use multiplication sign in formulae of regression report
* [ES] allow for DL modules to define functions of 4 and 5 parameters
* [ES] fixed compilation under FreeBSD-5.1 and OS/X
* [ES] on 64-bit platforms, when specific compiler/optimization
combinations were used, some dialogs could crash randomly
* [ES] on 64-bit platforms, when specific compiler/optimization
combinations were used, X run-time warnings could be issued
about unrecognized XKeySym's
* [ES] set filling defaulted to even-odd filling rule in the X11
driver
* [ES] fixed potential memory corruption
* [ES] fixed page size sync in the free mode
* [TO] fixed a race condition in the grace_np library
* [ES] enabled annotated values for HILO sets
* [ES] added IMIN(x) and IMAX(x) functions returning index of minimal or
maximal value of array x
* [ES] updates for T1lib-5.0 API
* [WB] documented commands for calculating running properties
* [MD] enabled font kerning in the MIF driver
* [ES] Grace might fail starting in the GUI mode when a certain
sequence of command line arguments was passed
* One more slight adjustment to the fix for bug 135064
(http://bugzilla.gnome.org/show_bug.cgi?id=135064)
Entering numbers that start with the numeric point character ('.")
are now visibly displayed.
* Adjustment to the fix for bug 135064
(http://bugzilla.gnome.org/show_bug.cgi?id=135064)
Fix to remove a potential spurious initial thousands separator
character after a change sign operation.
Fixed calc man page examples to move -f to the end of the line.
Thanks goes to Michael Somos <somos at grail dot cba dot csuohio
dot edu> for pointing this out.
Linux and gcc now compiled with -Wall -W -Wno-comment.
Fixed a post increment that was reported by R. Trinler <trinler at
web dot de> and fixed by Ernest Bowen <ernie at turing dot une dot
edu dot au>.
Fixed pi.cal to not depend on the buggy pre-2.11.9 post increment
behavior.
Added config("cygwin") to determine if calc was compiled under Cygwin.
The config("cygwin") is a read-only configuration value that is 1
when calc was compiled under Cygwin and 0 otherwise. Regression
tests 949 and 950 are skipped when config("cygwin") is true.
The Makefile variable HAVE_NO_IMPLICIT is empty by default so that
the Makefile will test if the compiler has a -Wno-implicit flag.
Added HAVE_UNUSED Makefile variable. If HAVE_UNUSED is empty,
then the Makefile will run the have_unused program to determine
if the unused attribute is supported. If HAVE_UNUSED is set to
-DHAVE_NO_UNUSED, then the unused attribute will not be used.
The Makefile builds have_unused.h which defines, if the unused
attribute is supported:
#define HAVE_UNUSED /* yes */
#define UNUSED __attribute__((unused)) /* yes */
or defines, if the unused is not supported (or if the Makefile
variable is HAVE_UNUSED= -DHAVE_NO_UNUSED):
#undef HAVE_UNUSED /* no */
#define UNUSED /* no */
Fixed numerous warnings about comparison between signed and unsigned
value warnings and unused parameter warnings in version.c, zrand.c,
string.c, shs1.c, shs.c, qtrans.c, qmath.c, qfunc.c, md5.c, matfunc.c,
hist.c, file.c, const.c, blkcpy.c, seed.c, opcodes.c, func.c, qio.c,
zrandom.c, custom/c_argv.c, custom/c_devnull.c, custom/c_help.c,
custom/c_sysinfo.c, addop.c and calc.c.
Fixed some typos in this file.
By default, compile with -O3 -g3. The Makefile comments on how some
distributions might need to use -O2 -g or -O -g.
features:
* Rich set of number classes
* Elementary, logical, transcendental functions
* C++ as implementation language brings efficiency, type safety,
and algebraic syntax
* Memory efficiency
* Speed efficiency
* Interoperability
* Fixed bug 135064. Changing the sign of a large number (when "Show
Thousands Separator" is on and this is not the C locale), no longer
corrupts the display.
My special thanks to Miloslav Trmac for fixing this problem in a
really elegant manner. This is an important change to the way that
numbers are displayed.
The fix involved resetting all the internal calculations in gcalctool
to be done in the C locale, and then localized (radix character and
thousands separator), just before the number is displayed.
I'd appreciate it if everybody could give this a good thrashing in as
many locales as possible to make sure that it's fully working.
* Fixed bug 135328. Added Shift-slash as a recognized alternate for the
divide operation (needed by the be-latin1 keyboard layout).
Changes since 4.3.44:
* Fixed bug 134540. gcalctool now correctly handles the digits
0123456789 which are shifted about the accented characters on a
French keyboard.
* Fixed bug 134484. Doing "3 x! x! x!" no longer causes gcalctool to
lock up.
Overview of changes in gcalctool 4.3.44
* Fixed bug 133764.
- "Gradients" was still appearing when in Scientific mode (instead of
"Gradians".
- In the x^2 button, the 2 should not be italicized.
- In the x^2 and x^y buttons, the x should be italicized.
- The View Thousands Separator menu item should not remain active during
an error condition.
Overview of changes in gcalctool 4.3.43
* Fixed bug 133590. The About box now lists the documenters of gcalctool.
Overview of changes in gcalctool 4.3.42
* Fixed bug 132582. Adjusted the gcalctool titlebar to use a hyphen
(rather than square brackets) to show what mode the user is currently
using.
Overview of changes in gcalctool 4.3.41
* Fixed bug 132570. Adjusted UI to use spacing to delineate groups rather
than frames (per the HIG).
Overview of changes in gcalctool 4.3.40
* Fixed bug 131571. User defined constants are now read/written out (as
gconf resources) with no thousands separator and with a radix of ".".
Overview of changes in gcalctool 4.3.39
* Fixed bug 131594. The "Insert ASCII View..." menu item and the
"Insert" button no longer use the GTK_STOCK_CONVERT stock icon
(as per the HIG).
configure tries to determine if -lm is needed by compiling
int main() {
(void)sin(0.0);
; return 0; }
and see if linking fails. But gcc3.3 optimizes that to just "return 0;"
Changes since version 1.11.7:
1.12.1 2003-12-01
Corrected omission of file "lib/udunits.inc.in" from
distribution.
Ported to Mac OSX (I hope).
1.12.0 2003-08-29
Corrected definition of "apothecary_pound".
Corrected documentation of "common_year" in the units
database.
Modified the syntax of a couple of statements in
file "src/utlib.c" to accomodate the, apparently,
non-conforming C/SX C compiler on NEC SX-4 SUPER-UX
systems, which can't dereference a pointer returned by a
function.
Added "mi" to database as alias for "mile".
Corrected documentation on origin-shift in unit
specifications.
Ported to systems with sizeof(double) <
sizeof(DOUBLE PRECISION).
Added determination of Fortran type equivalent to C pointer
to configuration script.
Added utIsInit() and utisopen() to the API.
Corrected Hertz symbol: changed from "hz" to "Hz".
Corrected reference to udunits(3) library in udunitsperl(1)
manual-page.
Added support for Absoft Fortran.
2.4.3 --> 2.4.4:
----------------
Bug fixes:
NetCDF error messages should now be correct. No more "unknown errors"!
2.4 --> 2.4.1:
--------------
Bug fixes:
- Scientific.MPI did not contain the _C_API object needed by C extension
modules that call MPI.
- The arguments to the receiveString method are now optional, as documented.
2.3.3 --> 2.4:
--------------
Bug fixes:
- Memory function calculation in Scientific.Signals.Models
returned a wrong value for the first point.
- Some indexing problems in Scientific.IO.NetCDF were fixed;
none of them caused wrong results, just unjustified exceptions.
2.3.2 --> 2.3.3:
----------------
Bug fixes:
- The method divide() assumed the wrong coefficient order.
New features:
- Module Scientific.Signals.Models
- Class Scientific.Statistics.Histogram.WeightedHistogram
2.3.1 --> 2.3.2:
----------------
Incompatible changes:
- Specification of routines in Scientific.BSP changed.
2.2 --> 2.3.1
-------------
New features:
- New modules Scientific.BSP and Scientific.BSP.IO
Changes since 4.3.35:
* Fixed bug 131059. Fix to allow the thousands separator to be used
correctly with the creation of the initial constant values in the
Russian locale.
* Fixed bug 130078. Changed the y^x button label to x^y (really x
superscript y). Adjusted the tooltip message to "Raise displayed
value to the power of y".
* Fixed bug 130282 again. Needed to remove the "|| tsep[0] == '\0'" check
from the get_tsep() routine in order to get the thousands separator to
correctly work in all locales. Note that there is no thousands separator
now for the C locale.
Changes sinec 4.2.83:
o Many bug fixes.
o Further work on enhancement request 125873. As the user is typing
in input, the display will now show the thousands separator
(if checked).
o On a Solaris keyboard, Shift-"^" is
GDK_asciicircum/GDK_SHIFT_MASK. This keyval/state pair needed to
be added to the Xor recognized mappings.
o gcalctool can now optionally show the thousands seperator
character for fixed point numbers displayed in the decimal
base. Same for numbers stored in the memory registers. There is
a new "Show Thousands Separator" menu entry in the View menu to
set this.
o Online help updated.
o Updated the gcalctool man pages.
o Install "gnome-calculator" symlink as reqested by Glynn Foster.
Pkgsrc fixes:
1) Install trans directory.
Official bug fixes since bug fix 4:
1) A wrong return format for `IsomorphicSubgroups' applied to cyclic groups.
2) A wrong `true' result of `IsSubset' for certain algebras.
3) Segmentation faults and other strange behaviour when assigning
finite field elements of different characteristics into compressed vectors
4) A bug in the subgroup conjugation test for permutation groups that are
not subgroups.
5) A missing method for `BaseOrthogonalSpaceMat'.
6) A missing `Set' call in the construction of the global variable
`AUTOLOAD_PACKAGES'.
7) A wrong display string of the numerator in rational functions returned
by `MolienSeries' (in the case that the constant term of this numerator
is zero).
8) A strange behaviour of `Intersection' for the case that a strictly
sorted list is the unique entry of the list that is given as the
argument; in this situation, this entry itself was returned instead of
a shallow copy.
9) An error in the basis of a product space of algebras.
10) Possibly wrong result of `Centre' for pc groups.
11) Possibly wrong result of `DirectSumDecomposition' for matrix Lie algebras.
12) An error in `LieNormalizer', `LieCentralizer' for zero subspaces.
13) An error in the computation of matrices of adjoint modules.
14) A strange error message when constructing the simple Lie algebra of type
B1.
15) An error in `ModuleByRestriction'.
16) An error in `IrrBaumClausen' for the trivial group.
17) An error with vector space bases of row spaces over fields which
neither are prime fields nor contain all entries of the vectors.
18) An error with `IsMonomial', when it uses the function
`TestMonomialFromLattice' (i.e., in hard cases, likely for characters of
nonsolvable groups).
Errors 1, 3, 5, 6, 9, 12, 13, 14 and 16 may cause GAP to stop with an error
message, errors 2, 4, 7, 10, 17, and 18 may cause wrong results.
- teTeX 1.0.x packages have been moved to teTeX1* directories.
- teTeX 2.0.x packages have been moved to teTeX* directories and their base
name has been changed to teTeX (instead of teTeX2).
This python module implements constants and functions for working with IEEE754
double-precision special values. It provides constants for Not-a-Number (NaN),
Positive Infinity (Inf), and Negative Infinity (-Inf), as well as functions to
test for these values.
The code is implemented in pure python by taking advantage of the 'struct'
standard module. Care has been taken to generate proper results on both
big-endian and little-endian machines. Some efficiency could be gained by
translating the core routines into C.
--------------------
Fixed bugs
o There was several memory leaks due to bad management of Python

for specific packages. We will look into this again in the future.
