The default currency type I've seen used for accounting is a decimal with 4 digits trailing the decimal. I forget the leading digits, but it is something like 14. Basically I think the idea with 4 digits after the decimal is that the smallest denomination you can have is 1 penny, and that allows you to calculate percentages of pennies accurately to a hundredth of a percentage point.
