fmod

(PHP 4 >= 4.2.0, PHP 5)

fmod — Returns the floating point remainder (modulo) of the division of the arguments

Description

float fmod ( float $x , float $y )

Returns the floating point remainder of dividing the dividend (x ) by the divisor (y ). The reminder (r) is defined as: x = i * y + r, for some integer i. If y is non-zero, r has the same sign as x and a magnitude less than the magnitude of y .

Parameters

x: The dividend
y: The divisor

Return Values

The floating point remainder of x /y

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
?>
