Technician charges

When you click on Add Time Entry, and place your time in, it obviously divides the hourly rate by the amount of minutes you enter. How do I stop SD+ from making the charge go to 10 decimal places?

Currency should only go to 2 decimal places (an assumption here, I must admit, but I've not seen a case where someone's currency goes to 10 decimal places). Have I not set a setting correctly somewhere?

My Time Spent reports are showing charges to the departments with the currency going to 10 decimal places. I can of course override this when entering the time by removing all decimal places and manually rounding it to 2 decimal places, but this seems unnecessary.
