What about a string like ".0"? A degenerate example I know. :)

Not all languages use the characters 0 to 9. Happily, there is
[NSCharacterSet decimalDigitCharacterSet] and NSString's
stringByTrimmingCharactersInSet, which you can use together to do this
more nicely.
You can also use the above to check if NSDecimalSeparator has any numbers
in it, then maybe just don't touch the string at all.
