A compiler somewhere probably does the same thing for floats, except with
additions/subtractions to the exponent.

I think that for integers an addition is still better, but I may be wrong.
But now a days, it doesn't make much difference.

I still use shifts reasonable often, but then again, I have uses for 2^x :)
