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
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
?>
