I'd probably do this with a regex plus a quick test for in-range values -- something like (untested): if ($number>0 && $number<24 && preg_match('^[0-9]{1-2}(\.[0-9]{1,2})?$', $number)) do_stuff; You could also tweak the regex to filter out out-of-range values and dispense with the range checks -- something like (again untested): if (preg_match('^(1?[0-9]|2[0-4])(\.[0-9]{1,2})?$', $number)) do_stuff; Cheers!
