fmod — Returns the floating point remainder (modulo) of the division of the arguments
$x
, float $y
) : float
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.
xThe dividend
yThe divisor
The floating point remainder of
x/y
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
?>
