Feature Request: More digits for percentage values.

[HarikalarKutusu]

On age and gender percentage values, there are 2 significant digits, like 0.12... As these also include rounding, when we sum them the result will not be 100% most of the time.

It would be very nice if we can have two more significant digits in these fields, like 0.1234 showing 12.34%, so that one can sum them and do the rounding.
