fmod
(PHP 4 >= 4.2.0, PHP 5, PHP 7)
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 remainder (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
