I've just started "tinkering" with the floating point unit. I was coding a piece of an equation when I realized that the CPU could've handled it as it was still integer math at that point. My question is which processor is faster with integer math, the CPU or the FPU?
In general integer maths is faster than floationg point math.
But, and theres always a but, if the overhead from loading and storing values is not going to come into play then multiplication is faster on the FPU. Read the Agner Fog guide
