Thanks for the warning - all numerical values will be base10, sometimes in scientific format, so the looks_like_number call should work in this case.

So, looks_like_number only works for base10 (and below) numbers i.e. hexadecimal values with or without a trailing 0x will return false?

Although, of course not knowing the number base for numerical values will cause all kinds of other problems! ;)
