Suggestion: rounding of tax

Hi Andrei,

Seems like currently the tax calculation of NC doesn't include rounding based on the sub-total. Here is an example:

If the Sales Order Sub-total is: $100.05
Tax percentage is: 10%

The calculation result from current NC is: $10.00, while if we consider the the most frequently used rounding (rounding to 1 when great than 0.5), it should be $10.01

Can we please add a option to support this rounding for the tax calculation?

Thanks.

Hi,

All rounding is handled in the "RoundPrice" method of \Libraries\Nop.Services\Catalog\RoundingHelper.cs class. As you may see it uses the "Math.Round" method (.NET functionality). Please find more info at http://stackoverflow.com/questions/977796/why-does-math-round2-5-return-2-instead-of-3-in-c:

So you can simply replace

value = Math.Round(value, 2);

with

value = Math.Round(value, 2, MidpointRounding.AwayFromZero);

I've just also created a work item
