Refactoring: Magic Numbers

Another type of refactoring patterns is the Magic Number pattern.

Magic numbers are numbers with special meaning and value that usually are not obvious, such as PI. They are really nasty when you need to reference the same number many times. If the number might ever change, making the change is a nightmare. Even if you don’t make a change, you have the difficulty of figuring out what is going on.
