Vendor Plan Commission Problem


I set my commission to 1.00% in vendors plan.

Decimal point I main(and only) currency is comma

Total in orders is 758,74.

But income is only 7,00 instead of 7,58 .

For some reason every order is round to 1 as I can see in accounting

I know it has something to do with converting these prices from float to string and float again and therefore i'm losing decimal. Is there a way to make it work and to count income based on value with comma with more precision?

Thank you,
