Can you make the algorithm choose to round one of this = 33.3, 33.3, 33.3 ?

Hello, sometimes when we have percentages we end up with periodic pure decimals resulting of 1/3 . Can you make the algorithm to choose arbitrarily to round one of them? to end up with 33.4, 33.3, 33.3.

Currently it says the following error:
The sum of the items in your column isn't equal to 100

Thanks.
