packed decimal:
I think he's saying keep amounts in pennies as binary fields.
Convert to dollars + decimal point + cents when you display
these fields.
That works for addition and subtraction. It gets more complex when
you need to do multiplication (such as computing interest). That
involves shifting and rounding after the multiplication. IOW: To do
6%, multiply by 6 and then shift 2 positions to get back to pennies
(after adding 50 to round up/down).
