It's Hard To Compare Floating-Point Numbers

Last week I posed a problem: Suppose you have an inheritance hierarchy that lets you represent integers or floating-point numbers. How would you define comparison within your hierarchy? We can restate this problem in a language-independent way: How can we compare two numbers, either of which might be integer or floating-point?
