What if you only need to store negative integers?

• duaneb 14y ago
  Isn't that the same situation as only storing signed integers? The arithmetic is just a little different.

    No, you get room for one more negative int. x = x < 0 ? -x : x; is a common buggy abs(), e.g. when printing an integer. One should test if it's negative, perhaps print the '-', and then ensure it's negative for the rest of the per-digit code.
