Currency with 4 decimal places

Hello All,

Ran into a legal requirement that all prices need to have 4 decimals. The actual physical currency only supports 2, therefore the final total price collected from customer for a transaction will end up with only 2 decimal places.

This is still a bit tricky, and any help or experience is appreciated!

As a starting point just set the currency to 4 decimal places.. Following through with just this approach, we can see that on POS screen and sale receipt all appears to be fine with the 4 decimal places. Even noticed that total on screen does show the 4 decimals but calculations are made to support 2 and then 0's are added to the end.... Which isn't too bad for what is actually needed.
