Hi, Your results may be skewed. If you are dividing integers by 2 it's not the same as multiplying an integer by 0.5. In the first case, you are performing an integer division, whereas in the second case you are performing a floating point operation (which results in the end in a cast back to integer.)
If that's what you did, testing operations on an integer, then the result is not surprising.
