Open Source C++ Scientific Calculators

Integrated Development Environment for some microcontrollers based on 8051(e.g. AT89S8253). Supported languages are Assembly and C. It has its own simulator, assembler, editor and many other tools. See the project web site for more details and the newest updates.

Advanced Trigonometry Calculator (ATC) is an open-source mathematical computing engine written mainly in C/C++. Created in 2011 and maintained by Renato Alexandre dos Santos Freitas, ATC is designed as a practical Windows desktop application for advanced calculations, automation, and technical problem solving. ATC supports equation solving, polynomial tools, complex numbers, matrix calculations, statistics, physics, geometry, unit conversions, DSP/FFT operations, and scripting. It can also process batch TXT files, making it useful for repeatable calculations and automated workflows. The project also includes ATC Online Alpha, a WebAssembly-based version that brings parts of the ATC engine to the web. ATC is released under the GPLv3 license and is made in Portugal.

Engineering Calculator is a lightweight, yet handy math expression evaluation and unit conversion utility that is always at your fingertips.

Full featured graphical scientific calculator modeled after actual commercial hand held scientific calculators. Fully tested and error free (as far as I know). Comes with HTML documentation, test files and sample calculator scripts. Win Xp / Linux. Works also for Windows 7 Professional and Ultimate edition.

3-DPhysicsSim is an interactive 3-D physics simulator which allows you to create a scene filled with objects and see how the objects act in real-time when governed by the laws of physics. 3-DPhysicsSim was created with the help of Irrlicht, WxWidgets and Bullet

XiCalc is a scientific calculator, which evaluates a wide range of different expressions and supports standard mathematical functions. Additional functions and constants can be defined by the user. Latest version of source is for borland radstudio xe8. (can be downloaded at borland)

Command line molar mass calculator that provides typo checking and options for printing elemental analysis and saving a record of previously calculated molar masses.

tau is a simple, fast RPN scientific command line math tool with array processing, complex number support, plotting, unit conversions, built-in help, logic operations, statistics, signal processing, and many advanced functions. tau evolved to be efficient and practical. We listen to our user stories.

Tinger Calc is a powerful scientific calculator environment. It supports elementary math ( +, -, *, /, ^), trigonometric functions (sin, sinh, asin, cos, cosh, acos, tan, tanh, atan), exponential functions (exp, ln, lg, sqrt), math constants (pi, e), system functions (exit, quit, print).
