Yes. And two plastic bags will slow your fall more than one when you jump from a plane. > Try this: > printf("single rounding: %.40f\n", 130560LL * 1 / (double)12800); > printf("twice rounding: %.40f\n", 130560LL * (double)(1 / > (double)12800)); > Result: > single rounding: 10.1999999999999992894572642398998141288757 > twice rounding: 10.2000000000000010658141036401502788066864 > The 1st result is closer to 10.2 as the 2nd. By a completely negligible difference. And that is assuming it would hold for other values of 10.2, which I am not convinced. You are wasting your time and making the code less readable for no actual benefit. Regards, -- Nicolas George
