Reg expressions specify range

[Silver Machine]

Is is possable to use regular expressions to check numbers fall with in a range i.e. between 5.5 and 9.1 I can check for the numbers and decimals but wondered if I could specify the range? Any one know? I have looked around and cannot find anything.
Thanks Chris

If you think about it long enough I'm sure you could come up with something, but it is silly to try since you have the greater-than and less-than operators at your disposal.if ($x > 5.5 and $x < 9.1) {
# do something
}

I new there would be something but it never occured to me to do it like that thanks a lot Chris
