FMOD(3) 1 FMOD(3)
fmod - Returns the floating point remainder (modulo) of the division of the arguments
SYNOPSIS
float fmod (float $x, float $y)
DESCRIPTION
Returns the floating point remainder of dividing the dividend ($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
o $x
- The dividend
o $y
- The divisor
RETURN VALUES
The floating point remainder of $x/$y
EXAMPLES
Example #1
Using fmod(3)
<?php
$x = 5.7;
$y = 1.3;
$r = fmod($x, $y);
// $r equals 0.5, because 4 * 1.3 + 0.5 = 5.7
?>
