fmod

(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

fmodReturns the floating point remainder (modulo) of the division of the arguments

Description

fmod(float $num1, float $num2): float

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

num1

The dividend

num2

The divisor

Return Values

The floating point remainder of num1/num2

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
?>
