Hi,
we have an issue on a store where the amount sent to a payment gateway gets messed up somehow.
Example:
An order in the store is 1200.30

Rounded in order total (we have 0 decimals) the amount is 1200. This is what the customer sees.

This amount, 1200, is sent to the payment gateway but when the payment gateway does the callback they see the amount 1200.30, which is in the database, and throws an error?

This issue only occurs when using discount coupons in % which can cause the odd prices which would need decimals but we dont want any decimals to show on prices in the store.

Does anyone have an idea how to solve this? I have searched a lot in the forum but cant find anything.

We are using 1.3.9h
