Moontoast Math Library

![Source Code][badge-source] Latest Version ![Software License][badge-license] Build Status [![Coverage Status][badge-coverage]][coverage] Total Downloads, (*2)

Moontoast\Math is useful for working with integers that are larger than (or may become larger than, through mathematical computations) PHP's max integer value for a given system. On 64-bit systems, this number is 9223372036854775807. On 32-bit systems, it is 2147483647. When overflowing this boundary, PHP turns the number into a float, reducing precision (see the PHP manual entry for Integers)., (*3)

Moontoast\Math provides an easy-to-use wrapper around the bcmath extension, allowing one to perform mathematical calculations on numeric strings, going well outside the integer range of the system and maintaining arbitrary precision for more precise calculations., (*4)

Installation

The preferred method of installation is via Composer:, (*5)

composer require moontoast/math

Examples

$bn = new \Moontoast\Math\BigNumber('9,223,372,036,854,775,808');
$bn->multiply(35);

var_dump($bn->getValue());
var_dump($bn->convertToBase(16));

This produces the following output:, (*6)

string(21) "322818021289917153280"
string(18) "118000000000000000"

You might want to use BigNumber to work with a UUID, which is an unsigned 128-bit integer. For example:, (*7)

$uuid = \Moontoast\Math\BigNumber::convertToBase10('ff6f8cb0c57d11e19b210800200c9a66', 16);

This utility converts the UUID from hexadecimal (base 16) representation to a string representation of the unsigned 128-bit integer in decimal (base 10). You may now create a BigNumber object with it to perform calculations, if you wish., (*8)

$bn = new \Moontoast\Math\BigNumber($uuid);
echo $bn; // 339532337419071774305803111643925486182
