It can, of course, take advantage of those higher-performing math extensions but the library will fall back on pure PHP implementations of the math functions if they are not present. RAPIM is a work in progress and should be considered alpha quality software. I would appreciate and welcome all feedback, especially if you have experience in implementing math algorithms. But all programming, debugging and test writing help is welcome! Installing ---------- [](#installing) Installation of this project is very easy using composer: ``` php composer.phar require ionux/rapim:1.0.0 ``` If you have git installed, you can clone the repository: ``` git clone https://github.com/ionux/RichArbitraryPrecisionIntegerMath.git ``` Or you can install manually by downloading the zip file and extracting the contents into your project's source directory. Usage ----- [](#usage) Integrating these classes with your project is very simple. For example, after including the necessary class files (or using an autoloader), to perform calculations: ``` $math = new \RAPIM\Math; $result = $math->add($a, $b); ``` The result will be returned as a string value: ``` 87184393310133944941037516098150368062480930902710059558578327529121455801724207495015120248109543168498739812179 ``` Found a bug? ------------ [](#found-a-bug) Let me know!
