User visible changes.
Version 2.00 - 6 June 2012
General changes:
* Unit lists provide conversion to sums of units (e.g. feet and inches).
* Added --round (-r) and --show-factor (-S) options for use with unit lists.
* Added unit lists aliases (e.g. time, usvol).
* A python script, units_cur, can update currency data.
* Units now flushes its output so you can talk to it with a pipe.
* Units now works in UTF-8 if the system supports it.
* Added --locale (-l) option to set the locale.
* English units such as the gallon are defined in all locales, with US
definitions by default except in the en_BG locale. You can force
the desired definition (Great Britain or US) by setting the
environment variable UNITS_ENGLISH to GB or US.
* Revised and extended the documentation, with more examples.
* Added locale mapping to address Windows locale names.
* Updated and revised units database, including UTF-8 definitions and
the 2010 CODATA.
* Fixed parsing bug for "1..2" or "1.2.3". These now give an error.
* Unit names can end with a number in the form of a subscript that
starts with a '_', as in 'X_3'.
Changes for units definition files:
* Changed location and names of unit database, splitting off currency
Files are /usr/local/share/units/{definitions,currency}.units and
the personal units file is $HOME/.units instead of $HOME/units.dat.
(Under windows personal unit file is unitdef.units.)
* Personal units filename can be changed with MYUNITSFILE environment variable.
* Prefixes can be defined in any order: it is no longer necessary to
define longer ones before shorter ones.
* New definitions replace previous ones. Personal units file is read
after the system file rather than before.
* Changed syntax for function definitions. Instead of [in-unit,out-unit]
you must now write units=[in-unit,out-unit]. Use 'units -c' to find
places in your personal data files that need to be updated.
* Add optional domain and range to function definitions with syntax
domain=[min,max] and range=[min,max]. Either min or max can be
omitted to signal infinity.
* Unit list aliases can be defined with !unitlist command.
* Added !var and !varnot and !endvar to include definitions based on
environment variable settings.
* Added !set to set environment variables (if they aren't already set).
* Added !message to display a message
* Data files are in UTF-8, with !utf8 and !endutf8 commands to mark
definitions that require UTF-8 support.
* Improved error handling when reading units.dat.
Version 1.88 - 15 Feb 2010
* Updated units.dat
* Fixed bug involving readline version 4.2
Version 1.87 - 25 Sep 2007
* Units reads ~/.units.dat if it exists before reading the standard
units database.
* Added support for ** as an exponent operator.
* Type 'search text' to list units that contain 'text' in their name.
* Precedence of '*' changed to match precedence of '/'.
(Multiplication by juxtaposition retains a higher precedence than
'/'.) The --oldstar option selects the old precedence and --newstar
forces the new precedence.
Project moved to another developer.
The changes compared to 2.2.1 are:
o visual garbage fixed (curses version)
o made unquoted strings default, added "-q" flag to turn quotes back on
o made attributes menu more user friendly: no more question when
changing a single cell, one menu option optimized away
o added "-H" command line flag to hide row/column headers; in FLTK,
this means you can only change sheets via Ctrl-Shift-PgUp/PgDn
o expanded command line help
The changes compared to 2.2.0 are:
o Help system improved
o Compile fix for MacOS
o Link shared by default. Set option ENABLE_STATIC to statically link FLTK.
o Bugfixes for CSV export
o Bugfixes for console mode
o Added font styles bold and underline
The changes compared to 2.1.0 are:
o UTF-8 support for curses frontend
o various bug fixes
The changes compared to 2.0.2 are:
o switched to CMake as build system
o Win32 compatibility
o usage improvements in the GUI version
o various bug fixes
The changes compared to 2.0.1 are:
o Low-resource builds (leaving out the help system)
o various bug fixes
The changes compared to 2.0 are:
o Fix a possible crash and some minor bugs
o improve FLTK navigation and cell editing (moving around and
selecting cells now works while editing a formula)
o automatically start a string value when typing a letter
o fix build system
The changes compared to 1.09 are:
o Several bug fixes and changes how files are handled
o FLTK user interface
o Built-in Help and About screen (currently only in FLTK)
o License changed to GPL (see mbox file in doc folder for permission)
New Features of SNNS 4.3
Version 4.3 of SNNS features the following improvements and
extensions over the earlier version 4.2:
1. Included patches avaiable from the SNNS-development project.
2. License changed to LGPL v2.
3. Fixed some bugs in the installation configuration files.
1. The mpfr_get_decimal64 function (available only when MPFR has
been configured with --enable-decimal-float) has several bugs,
fixed by the get_decimal64 patch, which also provides testcases.
It corresponds to the following changesets in the 3.1 branch:
8373, 8378, 8380.
2. The ternary value returned by the mpfr_strtofr function can
be wrong under particular conditions (example). This is fixed
by the strtofr-ternary-value patch, which also provides
testcases. It corresponds to the following changeset in the 3.1
branch: 8399.
Note that tests might need the package installed.
Changes in version 1.0.1:
- Switched to automake 1.11.6, see
https://lists.gnu.org/archive/html/automake/2012-07/msg00023.html
- #14669: Fixed extraction of CC from gmp.h
- Fixed case of intermediate zero real or imaginary part in mpc_fma,
found by hydra with GMP_CHECK_RANDOMIZE=1346362345
Changes:
Version 1.1.8
* Fixed bugs in the Fortran interface.
* Updated pkg-config file.
Version 1.1.7
* Fixed wrong derivative calculation for erf function.
Version 1.1.6
* Added support for erorr function (erf).
Version 1.1.5
* Re-licensed under GNU Public License version 3.
09/09/12 - Allow use of editline library in Mathomatic, because somehow
use of GPL libraries in LGPL code is not allowed, and GNU readline
is GPL. I am so confused about this Debian bug#687063:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687063
Based on the bug report's information sources,
it appears he is saying the truth about this license issue,
so I will have to upload new versions of
Mathomatic with editline instead of readline to Debian.
The only noticeable difference should be it doesn't save
the history between Mathomatic sessions.
I will comply with all that request it,
though most distributions do not include editline,
which has no major licensing restrictions. Readline is still
perfectly usable and good as before, you just have to link
it in yourself.
09/10/12 - Going to have to make a new release already, 2 days after the last
one, so I can upload this readline licensing fix to Debian by
linking with editline. There is no reason for anyone to upgrade
to version 16.0.4, unless you wish to link with editline instead
of readline. The proper code has been added. All you have to do
is have the editline libraries loaded on your system,
and run "make EDITLINE=1" to compile and link Mathomatic with
editline.
Mathomatic version 16.0.4 released Monday 09/10/12.
CHANGES MADE TO MATHOMATIC 16.0.2 TO BRING IT UP TO THE NEXT VERSION:
New command "set load" loads the current set options startup file again,
displaying the startup file as it reads it in.
If the file doesn't exist, or something is wrong, then an error message is
displayed and the set command returns with failure.
Accidently putting "load" in the startup file is now handled correctly.
08/09/12 - Allow "matho-primes all" and the command "list primes all" in
Mathomatic to continually output consecutive prime numbers.
08/12/12 - Fixed any rman errors in the makefile so they won't be ignored.
08/17/12 - rmath and matho no longer set the debug_level or modulus_mode,
so they can be set by the startup options file.
08/19/12 - Allow the repeat prefix on the approximate command, making it
approximate and simplify as much as the calculate command
does. Hopefully someday it will just give a temporary
result, too. Numerical input into the symbolic math library
now uses "repeat approximate" instead of just "approximate"
to approximate the user's input, so the result is the
same as the Mathomatic application's result.
Disallow the same warnings to be repeatedly displayed, if the
current warning is the same as the previous warning.
08/20/12 - Allow directory names as read command arguments, instructing
the read command to change the current directory to the specified
directory. Without any arguments, the read command now does an
"ls" command in Unix/Linux, and "dir" under MS-Windows, listing
the current directory contents. Running Mathomatic with a
directory name argument now conveniently changes directory to
that directory, then gives you the main prompt.
08/28/12 - Made "integer" type variables much more useful. For example,
the following now happens generally:
1-> i^(4*integer)
#1: i^(4*integer)
1-> simplify
#1: 1
1-> i^((4*integer) + 1)
#2: i^((4*integer) + 1)
2-> simplify
#2: i
2-> i^((4*integer) + 2)
#3: i^((4*integer) + 2)
3-> simplify
#3: -1
3-> i^((4*integer) + 3)
#4: i^((4*integer) + 3)
4-> simplify
#4: -1*i
08/29/12 - Displays "Calculating..." whenever autocalc is used now.
08/30/12 - Added ability to set the normal text color.
Still defaults to no color. Use "set color 0" to set the normal
text color to green, as it has been for many years in the past.
08/31/12 - Removed the "set preserve_surds" option, since the approximate
and calculate commands all take care of undoing that.
The code remains, however "set preserve_surds" is no longer
advertised. I have never used it.
Surds are preserved, for accuracy's sake, by default.
09/05/12 - "set" as a null set option works now, so no one will have any
trouble setting-up the set options startup file.
Mathomatic version 16.0.3 released Saturday 09/08/12.

- it is generally not recommended to call such methods in list context
as they should always be called in scalar context.
- Resolves https://rt.cpan.org/Ticket/Display.html?id=74693
- thanks to Shawn Laffan for the report and the patch.
3.0203 November 17, 2011

-bugfixes, cleanup, other minor improvements
pkgsrc note: shlib major changed
CHANGES MADE TO MATHOMATIC 16.0.1 TO BRING IT UP TO THE NEXT VERSION:
A nice cleanup and documenting of everything, while my mind still works.
07/23/12 - Enabled links in "manual.pdf" (the Mathomatic User Guide
and Command Reference), they were not working before,
but they work great now.
07/24/12 - Allow -a option ("set alternative") with sets alternative
color mode, useful in MS-Windows when using Cygwin with the
MinGW compiled version.
07/27/12 - Two bug fixes today:
Fixed using rlwrap under Cygwin and possibly other places,
when running rmath.
get_yes_no() question asker wasn't working in Cygwin or rmath.
Fixed to always ask the question, even if the input is not a TTY.
07/28/12 - Reading directories and empty files gives an error now.
07/30/12 - Split off changes.txt to changes.txt and changes_series_15.txt.
changes.txt and NEWS now contain only series 16 changes.
Added tests/batman_gnuplot_bug.in to prove there is a plotting bug
in gnuplot itself.
08/01/12 - Removed directive to use large font in the CSS for all Mathomatic
documentation. This is so it can be browsed easily with a mobile
device. The font size should be set by the user.
08/02/12 - A one-sided expression with an equals sign now only sets the
expression equal to zero if autocalc didn't work on it. In the
Symbolic Math Library, or without autocalc enabled, all is the
same. This makes it more likely purely numerical input is only
calculated, even when preceded or followed by an equals sign,
when autocalc is enabled. Reason for this change:
Why would you want to set a constant equal to 0?
Fixed a bunch more error reporting bugs coded into version 16.0.1
of Mathomatic to apply identical operations to both sides of an
equation. All fixed now. Points to the error correctly now, too.
08/04/12 - Major change to Symbolic Math Library. It now works exactly like
the application when it comes to purely numerical input,
approximating and displaying the result, however sign variables
are not expanded and the result is not 100% simplified,
so running "simplify sign" afterwards helps with that.
To revert to the old way, just turn off autocalc, or set
the numerical input equal to some normal variable; then there
will be no automatic approximation nor simplification.
You can tell when an input has been approximated because it
was numerical input, because it will always be preceded with
"answer =".
08/05/12 - m4/degrees.m4 copied with m4/functions.m4, when installing with
"make m4install", thanks to a suggestion by Reini Urban,
maintainer of the Cygwin version.
Mathomatic version 16.0.2 released Monday 08/06/12.
CHANGES MADE TO MATHOMATIC 16.0.0 TO BRING IT UP TO THE NEXT VERSION:
07/06/12 - Confirmed successful compilation and testing with the
Tiny C compiler (tcc). Only needed to set the tcc linker
library directories to the current gcc library directories
to make it work (using the -L option).
Searched globally for the word "simply" and fixed many outdated
texts in the Mathomatic documentation and READMEs, deleting some
wrongly used "simply"s, too.
07/07/12 - Allow "set modulus_mode language", where language is C, Java,
Python, or positive.
07/08/12 - Now leaving the "UNIX" C preprocessor define alone,
when "HANDHELD" is defined. "UNIX" was previously
forced undefined.
07/11/12 - "make test", "make check", and ./t now display the actual
Mathomatic version number being tested.
matho-primes now has a -v (display version number) option,
like Mathomatic does.
Mathomatic now automatically clears out all old
numeric calculations if it runs out of equation spaces,
requiring no action from the user.
07/12/12 - The solve command never needs the "repeat solve" prefix anymore.
The repeat flag is always set for the solve command, so that
it will always do full simplifies when verifying.
Added quadratic formula derivation and proof to
"tests/quadratic.in".
07/17/12 - I came up with a swinging new and easy way to add, subtract,
multiply, divide, modular and integer divide,
and raise to the power of both sides of an equation by any
expression. To add x+1 to both sides of the current
equation, just type "+=x+1" at the main prompt. To divide both
sides by c^2, type "/=c^2". You can add stuff to non-equations
too, this way. Be sure and use the simplify command after this
if needed, because only a small amount of simplification is done
by default, just enough so you can see what is happening.
07/20/12 - Changed floating point to rational floating point conversion
routine (f_to_fraction()) to ignore converting anything with
over 15 digits, for greater accuracy.
This fixes some small accuracy bugs: "factor number 17!" now gives
an error instead of the wrong value.
07/21/12 - Integrate, Laplace, and Numerical Integrate commands now warn
when the current equation is not a properly solved equation.
Mathomatic version 16.0.1 released Sunday 07/22/12.

Changes since version 0.9:
- First release as a GNU package
- License change: LGPLv3+ for code, GFDLv1.3+ (with no invariant sections)
for documentation
- 100% of all lines are covered by tests
- Functions renamed:
mpc_mul_2exp to mpc_mul_2ui, mpc_div_2exp to mpc_div_2ui
- 0^0, which returned (NaN,NaN) previously, now returns (1,+0)
- Removed compatibility with K&R compilers, untestable due to lack of
such compilers
- New functions: mpc_log10, mpc_mul_2si, mpc_div_2si
- Speed-ups:
- mpc_fma
- Bug fixes:
- mpc_div and mpc_norm now return a value indicating the effective
rounding direction, as the other functions
- mpc_mul, mpc_sqr and mpc_norm now return correct results even if there
are over- or underflows during the computation
- mpc_asin, mpc_proj, mpc_sqr: Wrong result when input variable has
infinite part and equals output variable is corrected
- mpc_fr_sub: Wrong return value for imaginary part is corrected
variables, and customization should be done via INSTALL_ENV/MAKE_ENV
respectively. This also solves the internationalization issue fixed
in previous commit properly.
