Rounding issue

Dear developers,

At first thank you for the plugin. We use it for a while, but now we faced a problem, I could not solve.

I have two currencies:
– Forint with Number of Decimals 0. This is the default.
– Euro with Number of Decimals 2.

If I have an order with Euro the tax some places round up (6,42 -> 6).
If I change the Number of Decimals to 2 for Forint the problem disappear.

Do you have an idea how can I solve it?

Thank you!

Best regards,
Mark
