RFC: Constraints on Cash accounts

[Phillip J Shelton]

Not if I can not have the denomimator for the same currency different in
different accounts.  Electronic transfers are still done in AUD$0.01.  Thus
if I pay a fuel bill of $23.47 it will cost $23.47 if I pay with credit and
$23.45 if I pay cash.
