Read it out loud.

I would think adding a case to check the length of the string would tell you hundreds, thousand, millions, etc... and then another check to see if the next few numbers are zero so you don't need to print them... and then even a THIRD check to see if there is a zero between the first and the last so you don't have to say that one either..

Would you be able to provide an example of what you want to (in text)?
