As I see it the naive formula needs 6 multipications, 2 divisions and 3 additions/subtractions and the improved formua needs 1 comparision, 3 multipactions, 3 divisions and 3 additions/subtractions This look like a good deal. However for floting point computations I prevere good results over fast results. What do you meen with "correctness issues"? Andreas Klein
