    I know it's primitive. But I coded it in about 5 seconds and for some application it might be good enough.

    > , and for strings with more than one decimal place
    Not True. It declares anything containing something else than numbers and decimal ponit(s) as non-numeric.

    For a real application I'd use something like Abigail's Regexp::Common
