Rich Arbitrary Precision Integer Math for PHP

Description

This rich arbitrary precision integer mathematics (RAPIM) library for PHP is a project which aims to provide a completely self-contained solution for PHP projects that cannot install the GMP or BC math extensions. 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

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

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:
