(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
fmod — Returns the floating point remainder (modulo) of the division of the arguments
Description
Returns the floating point remainder of dividing the dividend (num1) by the divisor (num2). The remainder (r) is defined as: num1 = i * num2 + r, for some integer i. If num2 is non-zero, r has the same sign as num1 and a magnitude less than the magnitude of num2.
Parameters
num1The dividend
num2The divisor
Examples
Example #1 Using fmod()
<?php
$x = 5.7;
$y = 1.3;
$r = fmod($x, $y);
// $r equals 0.5, because 4 * 1.3 + 0.5 = 5.7
var_dump($x, $y, $r);
