Reed-Solomon error-correction codes over GF(256) — RS(255, 239), t = 8. Zero-dependency TypeScript library with ports in PHP, Python, Go, Rust, and C++. Licensed Apache-2.0.

...The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). Example: int num_variations = 100; int init_value = 10; MathParser mathParser = new MathParser(); mathParser.putVariable("x", init_value); mathParser.parse("2 + (7 - 5) * 3.14159 * pow(x, (12-10)) + sin(-3.141)"); for(int i = init_value; i < num_variations; ++i) { Double result = mathParser.execute(); mathParser.putVariable("x", i); }

This Python module provides basic facilities for mathematics on fixed-point numbers. The number of fractional binary digits is tunable, allowing near-arbitrary precision arithmetic. Arithmetic & functions such as sqrt, exp, log, sin & cos are available. For the latest releases please visit https://github.com/rwpenney/spfpm

...Single and partial derivatives are supported. Supported operators: +, -, *, /, **, +=, -=, *=, /=, **= Available functions: sin, cos, tan, asin, acos, atan, sqrt, exp, log, log10, sinh, cosh, tanh, asinh, acosh, atanh See README file for usage examples.

* Fully featured BASIC compiler (fully featured a la 1980s/Commodore 64 era!) * Nearly all familiar BASIC commands supported (PRINT, INPUT, IF... THEN, GOTO, GOSUB, DATA, etc.) * Lots of BASIC functions supported (SIN, COS, EXP, LOG, string functions such as LEN and MID) * All the traditional BASIC operators (unary -, NOT, OR, AND, >, >=, <, <=, = [equality operator], +, -, *, /, ^, function(...), = [assignment operator]) * Three intrinsic data types (all 64-bit): Integer, double precision floating point, and UTF-8 string. Arrays of any dimensionality....

...In the begin it was just a tool for computation of resistors values. Very similar to Speed Crunch as features Features: * Command line input * Built-in functions (log, exp, sin, cos, ...) * User defined functions * Infinite number of variables * Specific functions for computation of resistors value (E12, E24) rounding, parallel computation, k = 000, M = 000000 * Store the status (hystory of the commands, variables status) between sessions This software is OPEN SOURCE and released under GPL license so you can feel FREE to use, copy, share, (but above all) to study, analyze and modify it as you like (within the terms of the license).
