LibreOffice is the free power-packed Open Source personal productivity suite for Windows, Macintosh and Linux, that gives you six feature-rich applications for all your document production and data processing needs: Writer, Calc, Impress, Draw, Math and Base. This is the localized interface for libreoffice.

This is a collection of C++ libraries that provides a variety of functionalities for geometries (bezier curves, splines, etc.). Eigen3 is needed for most of the components to work since all of the vector and matrix math is done using Eigen3. CPPTest is used to perform unit testing on the components.

Gnofract 4D is a free, open source program which allows anyone to create beautiful images called fractals. The images are automatically created by the computer based on mathematical principles. These include the Mandelbrot and Julia sets and many more. You don't need to do any math: you can explore a universe of images just using a mouse.

Net::IPv6Addr provides functions for parsing IPv6 addresses in all formats described by RFC1884. If Math::Base85 is installed, formats described in RFC1924 are also valid. It will generate "IP6.INT." strings (as described in RFC1886) if you are inclined to play with DNS records.

Crypt::DSA is an implementation of the DSA (Digital Signature Algorithm) signature verification system. The implementation itself is pure Perl, although the heavy-duty mathematics underneath are provided by the Math::Pari library. This package provides DSA signing, signature verification, and key generation.

PEAR::Crypt_RSA allows you to use two-key strong cryptography like RSA with arbitrary key length. It uses one of the following extensions for math calculations: - PECL big_int extension version greater than or equal to 1.0.3 - PHP GMP extension - PHP BCMath extension for both PHP4 and PHP5

This module provides an extension to HTML::Template which allows expressions in the template syntax. This is purely an addition - all the normal HTML::Template options, syntax and behaviors will still work. See HTML::Template for details. Expression support includes comparisons, math operations, string operations and a mechanism to allow you add your own functions at runtime.

Liblouis is an open-source braille translator and back-translator. It features support for computer and literary braille, supports contracted and uncontracted translation for many, many languages and has support for hyphenation. New languages can easily be added through tables that support a rule- or dictionary based approach. Included are also tools for testing and debugging tables. Liblouis also supports math braille (Nemeth and Marburg). The formatting of braille is provided by the companion project liblouisxml.

Date::Business provides the functionality to perform simple date manipulations quickly. Support for calendar date and business date math is provided. Business dates are weekdays only. Adding 1 to a weekend returns Monday, subtracting 1 returns Friday. The difference in business days between Friday and the following Monday (using the diffb function) is one business day. The number of business days between Friday and the following Monday (using the betweenb function) is zero.

ABOUT THE ILMBASE LIBRARIES ---------------------------- Half is a class that encapsulates our 16-bit floating-point format. IlmThread is a thread abstraction library for use with OpenEXR and other software packages. It currently supports pthreads and Windows threads. Imath implements 2D and 3D vectors, 3x3 and 4x4 matrices, quaternions and other useful 2D and 3D math functions. Iex is an exception-handling library. If you have questions about using the IlmBase libraries, you may want to join our developer mailing list.
