Thanks for the info! But did you guys thought about fractional commodities those days? Or was it clear that it is going away?
The current value of held assets in another currency isn't really "counting" any more, it's a prediction of the outcome of some future transaction that hasn't happened. So I'm less concerned about exactly computing it than I am in never making a mistake in assets that I am counting, i.e. keeping in one account and only incrementing and decrementing the amount when a transaction occurs.
