Installation

composer require nickolasburr/floatcmp:^1.0

Usage

.. code-block:: php

use function floatcmp;

$a = 0.00528690; $b = 0.00528;

if (floatcmp($a, $b, 5) === 0) { /* * $a and $b are equal at given scale precision. * * Unlike a floating-point arithmetic library, * floatcmp() does not apply rounding to its * arguments but instead takes a fixed-width * scale approach like bccomp(). When bcmath * is available, floatcmp() will use bccomp() * for the float comparison. */ }
