[GNC] Customizing invoices (Helmut Eller

[john]

Not a currency: Currency smallest fractions are set by law in the currency's issuing country, the ISO4217 committee maintains a list, and GnuCash follows that list. Non-currency commodities are more user-configurable via the Security editor, though you'll make yourself crazy if you set something different from what fraction actually trades for securities. For commodities that aren't securities or currencies it may make sense to set some other fraction, as in the example of the user selling subscriptions denominated in years who wants a fraction of 1/12.

John Ralls
