fmod — Returns the floating point remainder (modulo) of the division of the arguments
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
.
num1
The dividend
num2
The divisor
The floating point remainder of
num1
/num2
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
?>
