Package math
Short Description AzaMath - Anizoptera CMF mathematic component. Arbitrary precision arithmetic (for huge integers; BCMath wrapper) and universal convertor between positional numeral systems (supported bases from 2 to 62 inclusive, and systems with custom alphabet; pure PHP realisation, can use GMP and core PHP functions for speed optimization).

FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Introduction
Provides functionality to work with large numbers with arbitrary precision (using BCMath). and universal convertor between positional numeral systems (supported bases from 2 to 62 inclusive, and custom systems; pure PHP realisation, but can use GMP and core PHP functions for speed optimization).
Features:
- Functionality to work with large numbers (integers, floats) with arbitrary precision (requires BCMath). Can work with floats (E notation too!) and without loosing precision (as far as possible). It supports all basic arithmetic, exponentiation, square root, modulus, bit shift, rounding, comparison, and some other operations.
- Very simple math for big integers (only integers!, has a native PHP realization and can use BCMath or GMP for speedup).
- Universal number (and huge number!) convertor between positional numeral systems (supported bases from 2 to 62 inclusive, and systems with custom alphabet; pure PHP realisation, but can use GMP and core PHP functions for speed optimization). Negative and huge integers are supported.
- Convenient, fully documented and test covered API.
Requirements
- PHP 5.3.3 (or later);
- BCMath (Binary Calculator Arbitrary Precision Mathematics) - Required only to work with arbitrary precision arithmetic operations;
- GMP (GNU Multiple Precision) - Recommended. Used to speed up number systems conversions and arbitrary precision arithmetic operations;
Installation
The recommended way to install AzaMath is through composer. You can see package information on Packagist.
Examples
You can use examples/example.php to run all examples.
Example #1 - Numeral systems conversions
Example #2 - Custom numeral system
Example #3 - Arbitrary precision arithmetic
Example #4 - Input filtration
Example #5 - Do some operations and then convert to base62
Tests
Tests are in the Tests folder and reach 100% code-coverage.
To run them, you need PHPUnit.
Example:
$ phpunit --configuration phpunit.xml.distOr with coverage report:
$ phpunit --configuration phpunit.xml.dist --coverage-html code_coverage/Credits
AzaMath is a part of Anizoptera CMF, written by Amal Samally (amal.samally at gmail.com) and AzaGroup team.
Arbitrary precision arithmetic part is partially based on Moontoast Math Library.
