math parser

Dentaku is a parser and evaluator for mathematical formulas

Color is a Ruby library to provide basic RGB, CMYK, HSL, and other colourspace manipulation support to applications that require it. It also provides 152 named RGB colours (184 with spelling variations) that are commonly supported in HTML, SVG, and X11 applications. A technique for generating monochromatic contrasting palettes is also included. The Color library performs purely mathematical manipulation of the colours based on colour theory without reference to colour profiles (such as sRGB or Adobe RGB). For most purposes, when working with RGB and HSL colour spaces, this won't matter. Absolute colour spaces (like CIE L*a*b* and XYZ) and cannot be reliably converted to relative colour spaces (like RGB) without colour profiles. Color 1.8 adds an alpha parameter to all <tt>#css_rgba</tt> calls, fixes a bug exposed by new constant lookup semantics in Ruby 2, and ensures that <tt>Color.equivalent?</tt> can only be called on Color instances. Barring bugs introduced in this release, this (really) is the last version of color that supports Ruby 1.8, so make sure that your gem specification is set properly (to <tt>~> 1.8</tt>) if that matters for your application. This version will no longer be supported one year after the release of color 2.0.

Calculates the haversine distance between two locations using longitude and latitude. This is done using Math formulas without resorting to Active Record or SQL DB functionality

A very fast way to turn TeX math equations into beautifully rendered SVGs, to embed on the web. This library is mostly written in C and is a general purpose wrapper to GNOME's Lasem.

TimeMath is small, no-dependencies library attemting to make work with time units easier. It provides you with simple, easy remembered API, without any monkey patching of core Ruby classes, so it can be used alongside Rails or without it, for any purpose.

An Asciidoctor extension to converts latexmath equations to SVG or PNGs

A Sass implementation of mathematical functions.

Jazz theory is a mathematical system of concepts and relationships, why not make an ActiveModel representation of those concepts?

This gem maintains MathJax at a system-wide directory.

Calculates the geo distance between two locations using longitude and latitude using Haversine, Speherical or Vincenty formula. This is done using Math formulas without resorting to Active Record or SQL DB functionality

Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it: * Uses degrees. * Draws in quadrant 1 (0-90 degrees). * Right hand rule: 0 degrees is east, 90 is north, etc. These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught in grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation.

Symbolic math for ruby. This gem can help if you want to get a simplified form of a big equation or to speed up similar calculations or you need an abstraction layer for math. Symbolic does not have any external dependencies. It uses only pure ruby (less than 400 lines of code).

Adds a liquid tag you can use to do server-side rendering of latex math using KaTeX

Ritex converts expressions from WebTeX into MathML. WebTeX is an adaptation of TeX math syntax for web display. Ritex makes inserting math into HTML pages easy. It supports most TeX math syntax as well as macros.
