Rounding off % values of labels in Pia chart

Hi All,

Here is task about Pia chart, How to Round off % value of Pia chart labels, and it should give 100% also after round off value.

example-For example, if the original percentages are 33.3%, 33.3%, and 33.3%, rounding each to 33% will result in a total of 99%. The discrepancy arises because the rounding of individual parts does not necessarily preserve the overall total. Small rounding errors accumulate, leading to a slight deviation from 100%.

So I want round off % values with accurate data.

Thanks
