Darn, you are right. I hate it when you do that to me. ;-)

The regexp can be repaired perhaps: (var ~ /^-*[0-9.]*[0-9]+$/).

Testing for [[:alpha:]] alone will also not do the trick because of "misformed" numbers like: "123.456.789", which should not be treated as numbers despite passing the [[:digit:]]-test. Thinking about it it is not possible to determine "number or not" based on characters alone:

Code:
-123.456  # is a number
123-456.  # is not


I hope this helps.
