Exercise 10: Parsing numbers
September 9, 2008

Summary

This exercise involves introducing yet another transformation type, the numeric transformation, which allows numbers to be added or multiplied. It is to be used to allow numbers, written in long form, to be parsed into their representative integers.

For example, "one thousand one hundred and eleven" is parsed to become 1111.
