We have instructors who use half points in the rubric and they are not adding correctly. For instance, 2 criteria broken down to 2.5, 2.0, and 1.5 points. The assignment total is worth 5 points. When one criteria is graded at 1.5 points and the other criteria at 2 points it doesn't add to 3.5. Instead, it is rounded and displays 4 points. If they are graded at 1.5 each it does add to 3.

Is it possible to actually choose 1.5 and 2.0 and have them equal 3.5 instead of 4? Is there a setting we are missing or is it just not designed to work this way?
