Unfortunatly checking for non-digits is not sufficient since these are all numbers:

Checking just for non-digits won't work on those. And you cannot just check for digits, E, e, and ., since these are all not numbers

The only thing that your technique will work for is integers -- certainly not the only thing meant by 'number'.
