mifflin has asked for the wisdom of the Perl Monks concerning the following question:
I need to determine if something is numeric.
By numeric I mean...
1. no alpha
2. no leading zeros ( 0001 or -0001 needs to be considered not-numeric)
here is what I came up with
Is this considered the right way to go about it? Is there a better way?
