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
.
例 1Using
fmod()
$x = 5.7;
$y = 1.3;
$r = fmod($x, $y);
// $r equals 0.5, because 4 * 1.3 + 0.5 = 5.7
