MathLib is a PalmOS shared library which makes a complete set of IEEE-754 double-precision math functions available to other Palm applications. These functions include all the standard routines normally accessed by including "math.h" on other systems, including trigonometry (with inverse and hyperbolic), logarithms, exponentiation, and miscellaneous helper functions.

galculator is a GTK 2/GTK 3-based scientific calculator supporting algebraic mode, RPN, and formula entry mode. Features include arithmetic operations plus precedence handling, full keypad support, trigonometric functions, power, square root, natural and common logarithm, constants (e, PI), and inverse and hyperbolic functions. It supports different number bases (decimal, hexadecimal, octal, and binary) and angle bases (radiant, degree, and grad).

Frink is a calculating tool and programming language designed to help you in the real world. It tracks units of measurement throughout all calculations and ensures that answers are correct. It converts between systems of measurement, and has a huge library of physical data. It is both a simple calculator for quick calculations and a full-fledged programming language for large tasks. It draws high-quality graphics, handles conversions between time zones, currencies, and historical values of the U.S. dollar and the British pound, translates between several languages, does date/time math, and more.

Schifra is a very robust, highly optimized, and extremely configurable Reed-Solomon error correcting code library for both software and IP core based applications with implementations in C++ and VHDL. Schifra supports standard, shortened, and punctured Reed-Solomon codes. It also has support for stacked product codes and interleaving. Schifra provides a concise, predictable, and deterministic interface which lends itself to easy and seamless integration into the development of complex data communication projects requiring Reed-Solomon error correcting code capabilities.

jHepWork (jWork) is an environment for scientific computation, data analysis, and data visualization for scientists, engineers, and students. The program is fully multi-platform (written in Java). Programs can be written in the Java, Jython/Python, and BeanShell scripting languages. Matlab/Octave is supported for symbolic calculations. The program can be used to display data and functions in D and 3D. It comes with a friendly IDE and a code assist.
