Are Hexadecimal and Binary Tested?
I guess it is important to realize that non-integers are represented in the computer in binary, and what that means. For instance, a Java variable cannot actually store the exact number .2, because .2 has no finite binary representation. Because of things like that, you get the bane of all programmers, roundoff error. Well, the bane of all programmers is the null pointer exception/dereferencing a null pointer/whatever your language likes to call it. But roundoff error comes in second for sure.
