note 57048 deleted from function.round by danbrown

Note Submitter: blackhole at ggot dot org ---- Sometimes you will want to make a number divisible by another (like rounding by 5s, or 10s, or 7s, or 1438s, or whatever) instead of just making it divisble by one such as round() with only one argument. The function that follows is fairly simply and behaves mostly as expected. <?php function divby($val, $by) { if ($val < 0) $val += -$val % $by; else $val -= $val % $by; return $val; } ?> divby(23, 10) will return 20 divby(77, 5) will return 75 divby(138, 7) will reuturn 133 divby(-23, 10) will return 20 note: the only way to return a negative value is to make BOTH values negative, for example: divby(-25, -10) will return -20 note also: if the value of $by is greater than $val then the function will return 0, for example: divby(3, 4) will return 0 divby(4, 3) will return 3
