"value is numeric" is a little vague; I went with a regex that's simple, but
won't catch quite a few variations. See perldoc -q 'is a number' for
alternatives.
By the way, what is this for? It looks suspiciously like you're using it
for database inserts or something along those lines; there are better
alternatives if that is the case.
