Esteemed Monks,

I need to figure out if a given number is larger than a specific floating point number format. For example, given a FPN with a precision of 4 and a scale of 3, they must be in the format of something like X.XXX, but needn't have all of those numbers. So 1 is valid, .45 is valid, 3.452 is valid, but 12.3 is not valid, nor is .34567.

I know there are other ways to do this, but I'd just assume use a regex if I can. I know how to look for specific numbers of certain chars using braces, but how do I look for n or less characters? I could run it through a filter first to pad the right and left sides with zeros before running it through something like: 

$float =~ /\A\d\.\d{3}\z/;

but I'd just assume do it all in one fell swoop. Negative numbers and exponents are edge cases that I'm not concerned about in this case.
