Descrierea

fmod ( float $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.

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
?>
