Great find. This is the most in-depth article I've read on this subject. I actually use this as an open-ended interview question at the game company where I work. The PlayStation 2 has a bunch of quirks with floating point numbers because it doesn't follow the IEEE standard - for example, floats don't become infinity when they overflow, they just get clamped to the maximum possible float. Now you can't use your FPU for the tens of thousands of floating point calculations that are happening per frame. Sure, your processor is faster, but it's fighting with one arm tied behind its back.
