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!

Mike
