# fmod

(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

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`. `NAN` (float) if the second argument is 0.

### 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);
?>`
