> > Is comparing floats slower then comparing ints? i.e. if (a < b) > They are much more slower. This is true, but if your just checking for a < b, sub a from b, store and check the sign bit. If the sign is 0 then a <= b... If you weave the code properly, you can do a check in about (from memory) 5 cycles... (compared to an int's 1 though) Leathal.
