Re: getting a number range from user input.. (weight)

OK, here is what it should do. I have a fixed range of weights from .5 to 20.0 Kg (kilogram) and for each weight it has a succeeding value, i cannot jump or just round off the numbers. So i need a range detector to do it. Because for each of the item below: > weight value > .5 9.45 > 1.0 10.71 > 1.5 11.97 > 2.0 13.23 I must get the exact value, so let say for example. I have 1.3 it should fall under 1.5 the idea i had was to do this, so i can detect where the number should fall.. range: .0000 => .5 1.001 => 1 1.501 => 2 2.001 => 2.5 2.501 => 3 3.001 => 3.5 and so on.. But i dont know how to do this on PHP Louie On Thu, 4 Nov 2004 20:23:53 -0700, Vail, Warren <warren.vail@schwab.com> wrote: > Not sure I completely understand what you are trying to do.
