Great, somebody who can read documentation. Very rare :-)

No, it is not undefined. it'll return "0" when ok would be set to false. So
the code is correct. 

The problem probably was that he entered probably non-decimal stuff into the
field so that it couldn't convert it to a number at all. I fixed it now that
you can only enter decimal numbers in a given range.
