Mathomatic 14.4.5
Portable, general purpose CAS (Computer Algebra System) written entirely in the C programming language more>> Portable, general purpose CAS (Computer Algebra System) written entirely in the C programming language
Mathomatic is a free software, published under the GNU Lesser General Public License (LGPL version 2.1). This is a console mode application that does quick calculations and symbolic math.
Mathomatic is designed to be as general and easy to use as possible, and as such, has no programming capability.
Mathomatic implements most of the rules of algebra for subtraction (-), addition ( ), modulo division (%), multiplication (*), division (/), and all forms of exponentiation (^). All arithmetic is double precision floating point with up to 14 decimal digit
Mathomatic compiles and runs under any operating system with a C compiler, especially GNU/Linux. There are no dependencies other than the standard C libraries.
Mathomatic has been under development since 1986 and now stands at 16,000 lines of code (including comments).
Main features:
- combine and solve algebraic equations,
- completely simplify, expand, and compare expressions,
- do calculus transformations (derivative, polynomial integral and Laplace, extrema, and Taylor series),
- help with series analysis (sum and product),
- do standard, complex number, and polynomial arithmetic,
- generate efficient C, Java, and Python code from equations,
- and perform quick calculations, all in color, for easier reading.
Enhancements
- "primes/mult" improved and renamed to "primes/matho-mult", so you can install as a unique program, if you wish. "primorial 1" works now, too. Roots command enabled in the symbolic math library.
- Fixed factor command parameter handling and results, it was not user friendly. Also fixed factor command for consistent behavior in the symbolic math library.
- Allow separate install of Mathomatic binaries and documentation in makefile.

Each skill (add, subtract, multiply, divide, algebra and roman numerals) has three skill levels (easy, medium and hard). The algebra problems are to solve for x. Select the desired skill and the skill level. A new problem will be displayed. Type the answer into the field provided and click on the "Enter" key (or press Enter/Return). If you are correct, you will see "Correct" displayed, and the Correct score will be incremented. If you are not correct, you will see "Incorrect" displayed, the correct answer will be displayed and the Incorrect score will be incremented.
Click on the "New Problem" button to get a new problem. If your answer is correct, the "New Problem" button will be pressed for you automatically after a few seconds. The % displayed is your overall score in percentage. Clicking on the "Reset" button resets all scores. Sound is supported. When you have ten correct answers you will hear applause. Sound can be turned on/off. Settings for sound, skill, and skill level are saved between sessions.
Enhancements: Improves compatibility with Leopard.
Requirements: Mac OS X 10.2 or later.
Internet Time Dockling 1.1
Internet Time Dockling - Internet time clock for the dock more>>

The docking menu shows the users current date/time, the UTC date/time , and an Internet date/Time stamp. All of these menu items are copied to OS X clipboard when selected.
Gambit-C 4.1.2
Gambit-C is such a great program including a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. more>>
Gambit-C 4.1.2 is such a great program including a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. Because the compiler generates portable C code it is fairly easy to port to any platform with a decent C compiler. The thread system is very efficient and can support millions of concurrent processes.
The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards. The full numeric tower is implemented, including: infinite precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers.
Major Features:
- Conformance. The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards and implements all optional features. Tail calls and first class continuations conform to the Scheme semantics. The full numeric tower is implemented, including: arbitrary precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers. Several extensions to Scheme are provided, including: lightweight threads, a foreign-function interface (FFI), and extended I/O capabilities (Unicode, networking, subprocesses, ...).
- Portability. Because the system is mostly written in Scheme and the compiler generates portable C code, it is easy to port the system as well as programs compiled with it to any platform with a decent C or C++ compiler. There is no reliance on a particular C compiler, although the system can take advantage of some gcc-specific constructs. The C code generated is oblivious to the endianness and word size of the target environment (32 and 64 bit architectures are currently supported).
- Performance. The compiler includes several powerful program transformations such as user procedure inlining, partial-evaluation, and lambda-lifting. With appropriate declarations in the source code the executable programs generated by the compiler run roughly as fast as equivalent C programs. Programs containing no declarations are also optimized without compromising the Scheme semantics by speculatively inlining predefined procedures. Thanks to an efficient implementation of continuations, the thread system is very efficient and can support millions of concurrent threads. The bignum library uses sophisticated algorithms that are in some cases asymptotically faster than those of GMP (GNU Multiple Precision Arithmetic Library). [Note: With the release of GMP 4.3.0 in April 2009, this claim is no longer true; ]
- Reliability. Stable releases typically have very few bugs. Bug tracking is done with bugzilla. Gambit-C has been used to develop large-scale real-world software in academic and commercial settings.
- Mac OS X 10.3 or later.

Poker Game mini 1.0.1
Poker Game mini - Video poker with a mathematical twist. more>> Poker Game mini - Video poker with a mathematical twist.
Has the same goal as video poker (make the best possible hand of five cards, given two opportunities to hold some cards and redeal the others), with a challenging mathematical enhancement: the cards have arithmetic suits, and these suits determine the value of the hand.
Since order is important, Poker Game mini allows the player to rearrange the cards in a hand, which can vastly improve (or utterly destroy) the hands value. For instance, reordering cards in the hand with the largest possible value (223,080) gives a hand with value 13.
Poker Game mini?s ?Hard Mode? actually locks held cards in place after a redeal, limiting in this way the user?s ability to take advantage of (or minimize the damage from) new cards constantly coming to the hand.
Enhancements
- Minor tweaks for Mac OS X 10.5 ("Leopard") compatibility.
