Question about typing in leading zeros before a decimal.

I just did a practice exam for PcM where in one question you have to type the answer into a field and I got an answer of 0.92. After finishing the practice exam to review my answers - it indicated my response is incorrect and the correct response is .92 - which is the same as my answer just without the leading zero in front of the decimal. My question is  - does this mean on the actual exam, we should always NOT type the leading zero in front of the decimal number, in order to get the correct response? This seems arbitrary and unfair to me. Or will the actual exam results get validated by a person? Please advise, thank you.
