Neptune is a simple programming language indented for quick mathematical calculations, e. g. shape field calculation or budget analysing.

A simple scientific calculator for complex number calculation. It requires the GTK+ toolkit.

rcal is an interactive calculator for DOS, that loosely mimics the behavior of "roller printing" calculators. It supports huge numbers, floating point and has extremely low hardware requirements.

mathSuite is a very powerful Mathematical Suite which deals principally with complex algebric and geometric operations. It is powered by the fabulous ExprEval C Parser. The main purpose of this project is fast math-oriented algorithm virtualization, with an optimized direct text interface. Also it gives you a very powerful and fast Calculus Environment which let you handle easily interchangeable variable lists, matrices, LOGS and Settings Layouts with optimized Items Lists Managing Engine. You'll also be able to execute your own scriptfiles with a basic math-oriented beta script language. Some feature regarding Matrices and Linear Algebra Operations are LU-Factorization, SVD Decomposition, Rank Calculator, Ill Condition Checking and more... There are also a very powerful Linear System Solver and Basic PRELoaded Functions Integrator Engine.
