PHP 8.0+ library to make working with money safer, easier, and fun for Malaysia Ringgit!

"If I had a dime for every time I've seen someone use FLOAT to store currency, I'd have $999.997634" -- Bill Karwin

In short: You shouldn't represent monetary values by a float. Wherever you need to represent money, use this Money value object.

<?php

use Duit\MYR;

$fiveMyr = MYR::given(500);
$tenMyr = $fiveMyr->add($fiveMyr);

list($part1, $part2, $part3) = $tenMyr->allocate(array(1, 1, 1));
assert($part1->equals(MYR::given(334)));
assert($part2->equals(MYR::given(333)));
assert($part3->equals(MYR::given(333)));
