I found a strange issue which didn't happen in Commerce 10.

It happens when:

1. I have a discount on the cart and calculating it produces a number with three or more decimal places. For example, item price - 34.55 with 10% discount produces the discount 3.455. Episerver rounds it to 3.45 and it is fine. The total then is 31.1.
2. Before the checkout, I am running a cart validation like in the Quicksilver. After validation the total changes to 31.095.
3. Once I save the cart, it changes back to 31.1.

In the Commerce 10, it did not change the total to the unrounded version after the validation.

Is this correct behavior?
