# fmod

(PHP 4 >= 4.2.0)

fmod -- Returns the floating point remainder (modulo) of the division of the arguments

## Description

float fmod ( float x, float y)

Returns the floating point remainder of dividing the dividend (`x`) by the divisor (`y`). The reminder (`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`.

Beispiel 1. Using fmod()

    $x = 5.7;
    $y = 1.3;
    $r = fmod($x, $y);
    // $r equals 0.5, because 4 * 1.3 + 0.5 = 5.7
