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.
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
?>
getrandmax
(PHP 3, PHP 4 )
getrandmax -- Show largest possible random value
Description
int getrandmax ( void )
Returns the maximum value that can be returned by a call
to rand().
See also rand(), srand() and mt_getrandmax().
