How can I ensure that a division of integers is always rounded up?
...ositive by checking that the signs of both integers are identical. Integer xor operator '^' on the two values will result in a 0 sign-bit when this is the case, meaning a non-negative result, so the check (a ^ b) >= 0 determines that the result should have been positive before rounding. Also note...
