Are you dividing signed or unsigned numbers?
When dividing unsigned numbers, both division and right-shift will round towards zero. In order to round towards the nearest integer, add 0.5*divisor to the value to be divided, but beware of integer overflows. When dividing signed numbers, things get more interesting, since the division will still round towards zero ((-1/2) == 0), but the right-shift will round towards negative infinity ((-1>>1) == -1). |
