The previous example (ralphcf@home.com) should work, but it will round toward zero. If you want to round down, try the following: floor($a/$b)*$b; If you need to round up, try: ceil($a/$b)*b); Can someone recommend a statistically correct rounding formula (that is, one that rounds .5 toward the even number)?
