You can't test all possible values (except for 32-bit float - 64-bit double takes about 50 years at current processor speeds ;-) but you can chose values (floating-point bit patterns) at random for a test lasting some minutes or even hours.

Could you provide the random number generation and otherwise help with this? I've only ever used integer RNGs.

Since you want to test random bit patterns, the easiest way is to generate a 64-bit integer and memcpy it to a double. In Christ, Steven Watanabe
