On any modern processor these operations are very very fast. Unless you
are bouncing an awful lot of balls you won't see any effect from using
these operations. Maybe if you tell us more about the application we can
help more. There are fast alternatives for these operations on machines
that only support integer or fixed point math. But, seriously, on all
the PC processors built in the last several years these operations are
too fast to worry about in most situations
