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 .

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
