Words to Numbers

Given a number in words in either English, Spanish, or French, you can get it's numerical equivalent. Furthermore, given a number you can get it spelled out in either English, Spanish, or French. You can also get the numbers spoken to you.

In short this is a "words to numbers" and a "numbers to words" program.

This application is useful if you get your Spanish billions confused with the English billions or if you need to translate a number.
