You'll find you can usually contrive not to feed non-numbers to your operations and don't need such a test often. A case statement can be used for a lot of simple data validation though.

The Great Guru replied in words which the Junior Programmer did not understand. The Junior Programmer sought to rephrase the Question, saying, "Stop me if I appear stupid." The great Guru, without speaking, reached over and pressed L1-A.
