Open Source Objective C Mathematics Software

A native Macintosh front-end and distribution for the GAP computer algebra system. It provides a Mac-like command editing environment and save/load, while making available graphical libraries compatible with xgap.

Quotient calculates an extended quotient based upon an input dividend, divisor, and scale, and has a repetend (repeating-decimal) detector to find patterns in the results.

Geodes is a mac application designed to do geometry and math like you can do in front of a sheet of paper. It both includes simple figures drawing (lines, circles) and high level analytic geometry.

MuPuPriNT (Multi-Purpose Prime Number Tester) is a primality and compositeness tester for many different types of numbers. It is basic, yet full-featured, and offers several different testing methods for each type of number. MuPuPriNT is built on the GNU Multiple-Precision (GMP) integer + rational library, and is available for Windows, OS X, and Linux. Source code is available as well, and can be built on any machine with Qt installed. As of version 2.0, MuPuPriNT is built on the cross-platform Qt application framework. There are currently two versions: MuPuPriNT and MuPuPriNT Extended.

Various computational physics projects for the Mac / GNUStep platforms.

6Vertex is an Objective C/Cocoa application (and standard C functions) for computing and visualizing matrix models generated with the 6-vertex model for computing boundary shapes and phase transition shapes for differently weighted vertices.

Computational modelling is a interdisciplinary field spanning many techniques and programming languages. AgenTools is a project dedicated to establishing increased modularity in scientific computing packages and a portal linking to other existing project

Baculator is a Reverse Polish Notation (RPN) calculator program with an infinite scrollable stack and support for most common mathematical operations as well as some more esoteric operations. Available for Unix/Gtk+, Mac OS X, and MS Windows.

Calculator-mAX is a cocoa calculator designed not so much to be useful, but to help those interested in learning to code on OS X using Cocoa. it is very basic, but with help it could be awesome. All you need is a Mac and preferably Tiger (with Xcode 2.0+

The purpose of the CoCalc project is to develop a simple RPN calculator application for use on laptops running OS X. It has been developed in Cocoa and Objective C, although it may change to a PyObjC application in the future.

Cracks of Reality is a high-quality fractal image renderer for Mac OS X. It is written in ObjC/Cocoa with the core engine in C to allow for a portable command-line version. Goals are speed, quality, and the ability to import other programs' descriptions.

Excalibur is a TeX/LaTeX aware spelling checker. It will also spell check plain text documents.

A fractal generator that relies on cooperative computing for complex calculation.

If you are looking for the 64-bit version, find it here: http://sourceforge.net/projects/gjsieve/files/200/gjsieve203.exe/download GJSieve is a basic, yet full-featured sieve and tester for numbers of several classifications, including Proth, Cullen, and Woodall. GJSieve is built on the GNU Multiple-Precision (GMP) integer + rational library, and is available for both Windows and OSX. Currently, the application differs greatly across platforms. This may change in the future. They both, however, do the same thing.

Coordinate Geometry application for Land Surveyors, Civil Engineers, and/or Land Planners.

MacHash is intended to be a HashCalc clone for Mac OS X. Sporting a neat Aqua interface, it allows you to calculate a variety of popular hash values like MD5 or CRC32 from diffent input sources such as a line of text or a file on disk.

ObjC framework for mathematical operations. Various DSP (inc. FFT + wavelet), statistical operations and more on vector and array types. Optimized for SIMD and multi-threading where possible.

A calculator for MacOS X that can convert numbers of various bases to any other base (within reason).

A CAS system for iOS.
