A functional HP-style command-line RPN scientific calculator
HPN is a functional - as opposed to microcode - cross-platform emulation of a classic 1970s Hewlett-Packard scientific calculator for any command-line interface. Its operations completely model the historical and groundbreaking HP-35 series, and functions to support the HP-45 and the later HP-65, 67 and HP-15C are in the pipeline.
Leibnitz is the calculator you've always wanted (even if you didn't know it!), short of handwriting recognition.

Mini-Calc is a very lightweight and easy to use calculator run in the console. It delivers everything you can expect from basic calculators, with more features added every major release.
A slim desktop calculator using RPN for easy, fast, and accurate computations. Suited for engineers and scientists. Knows a lot of numbers ;) Written in simple C++ using FLTK. Runs on Linux and Windows.
Can calculate mathematical expression. It have a module system witch make it very easy to add own functions. Other features are a graph painter and a tiny programming language designed too make it easy too write small mathematical tools.
Simple UI to test the effectiveness of a heuristic algorithm against the brute force method for path finding among an arbitrary number of arbitrarily placed points on a grid. This is an educational project, don't expect new and better methods.
The program evaluates ordinal expressions and relations. displaying the normal form output in plain text and/or TeX format. It supports notations for ordinals through and somewhat beyond those definable by the Veblen function.
PG Calculator is a powerfull scientific calculator and an excellent replacement for standard calculator. It ofers full customizable user inteface and looks like real calculator on user desktop. PG Calculator works in Algebraic and RPN mode.
The Penn Lambda Calculator is an interactive, graphics-based pedagogical software that helps students of linguistics and computer science practice the typed lambda calculus.
SimpliMath includes SimpliCalc, a simple, easy to use console-based calculator program and arithmatic parsing library. SimpliSolve is an equally easy to use and simple, yet powerful algebraic equation solver program and library.
Virtual TI emulates nearly the entire line of Texas Instruments graphing calculators, and offers features that speed up both debugging and testing of calculator programs. Windows version is quite stable but the Linux/OSX version is only in planning.
XCalc is an infix calculator for mobile devices that support J2ME, MIDP 1.0 and CLDC 1.0.Its main features are 2d and 3d plotting of functions and its usability. It uses the Real.java library http://sourceforge.net/projects/real-java.
The fast powerful CALC is a desktop scientific calculator, still is under development and tests. The objective is offer a good and easy to use mathematical tool. I hope you enjoy it.
Fraction calculator. For now only in text mode, but finally I plane making a GUI for Linux & other platforms. Finally all calculator's code will be accessible for both Linux/Unix architectures.
SigLab is a signal calculator for Scilab. Its goal is to ease the analysis of signal processing simulation results. It allows to view and to manipulate monodimensional signals in a interactive and easy way.
A desktop calculator/scientific calculator. Use as desktop/graphical calculator, web applet, or to show calculator operations: arithmetic, trigonometry, logarithms, complex numbers, memory, statistics. Features four bases, copy and paste, and history
