- But of course nobody is actually going to be representing the national
- debt using 64-bit arithmetic (as if someone in Washington runs the
- federal budget on Lotus 1-2-3 :->). We're talking about the
- balance-sheets of actual companies, which are probably an order of
- magnitude smaller even for really big conglomerates (anyone got any
- numbers?). Trillions do occur in such financial calculations,
- especially when trading in countries like Italy or Bolivia (where you
- don't reserve those three places for mills), but not very often.
- Besides which, they are generally down at the bottom line of the
- ledger (where the mills have disappeared; they are used for
- intermediate results). In fact, none of the financial software I
- wrote or used in Britain saved more than two places past the pennies
- (for percentage totalling calculations: calculate a line-item
- percentage, total line-by-line, and calculate a total percentage
- separately; if you haven't kept those digits the totals disagree. But
- the total value of the transaction is a whole number of pennies).
