Correct on both counts: (1) The dot should have been backslashed. (Edit: I've fixed the backslashing of .) (2) This works only for strings that don't contain dots anywhere to the left of the target "number". :). I didn't see any in his sample input, but the possibility supports the notion of "You have a problem. You think 'I will solve it with a regular expression.' Now you have two problems."

A better solution would probably leverage Regexp::Common, or the regular expressions revealed in perlfaq4 under "How do I determine whether a scalar is a number/whole/integer/float?"
