i,
I try to round each definition of tax rate but I think Magento 1.9 can do that
See this example of rounding tax generate difference of 0.01$
SubTotal: 737.08$
Tax line definition: 5% and 9.975%
If I calculate sum of tax and round only at the end you have
5% = 36,8540$
9.975% = 73,5237$
Total tax round 2 decimal : 110.38$
But if I round each taxe
5% = 36,85$
9.975% = 73,52$
Total tax round 2 decimal : 110.37$
Sombody can clarify if is possible to round each sub tax amount before calculate the sum of tax.
Thank you
