Installation

The recommended way to install this is through composer:

composer require "xethron/bignum"

Usage

<?php

use Xethron\Bignum\Math;

Math::add(7, 3); // 10
Math::subtract('1', '0.000001'); // 0.999999

// Default 20 precision
Math::divide(1, 3); // 0.33333333333333333333

// Set precision to 4 decimals
$third = Math::divide(1, 3, 4); // 0.3333
// Set precision to 2, resulting in rounding 0.9999 to 1
$one = Math::multiply($third, 3, 2); // 1

Math::round(0.5678); // 1
Math::round(0.16, 1); // 0.2
