WebFixed Point vs. Integer Numbers The good thing about fixed point is that it's actually an integer (i. e., good ol' byte, word, dword… whatever), only that you "define" it to be the way you want. You use the same "encoders" as an integer since it is an integer, and you use the same operations (i. e., in x86 you use mul , not fmul ) as with ...
