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.
範例 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
