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?
