Because of the rounding to two decimal places, people have different rounding rules. Rounding up (towards +infinity) is the accepted method in your past videos, but there was no mention of negative decimals or integers. So, just for clarity, could you possibly allow fractions in the answer, or be more clear in the question description, as it is a bit tough on people to round -0.125 if they haven't viewed your past videos, or prefer to round to the closest integer. Cheers.
