Dietz,
But your solution would only match a single digit instead of a number (not what the OP wanted). emphasis mine

Well see here is the quandry. You have interpreted it one way and I have another. Peamasii didn't define what exactly s/he meant by number. It could mean a single digit as I used, it could mean an integer which you described (which will match 0004 and miss -4 btw), or it could mean any number (pun intended) of things. For instance: 

use Scalar::Util 'looks_like_number';
if ( looks_like_number( $foo ) && $foo =~ /^\??$/ ) {...}

It is probably as common a mistake to assume what you are thinking is universally understood when asking questions as it is for the person that is answering to assume they know what you mean. I think we both fall into the latter category this time.

Cheers - L~R
