frankly I don't really understand it. I mean we do real geeky numerical computations only once in a while for a week, and then we spend a few months on CSS IE compatibility. I never remember what kind of computations break my numbers in what ways and how I know if I can safely use == or not in my case (and if I can't, how big the epsilon should be).
