Cloze question type: numeric questions where answer is zero, NULL field value is not calculated in score but displays as being correct.

When creating a cloze type questions where the correct answer value is zero, students will often leave the answer field blank.

When reviewing answers in the gradebook or question review interface, this results in the student and instructor visually seeing the question as being answered correctly with a green checkmark displayed, but in the gradebook it only records partial points for the question and deducts the null responses from the total score.

I've tested this by entering the zeros and not entering the zeros. The question that I entered zeros recieved full points while the same answers without the zeros only recieved partial points.
