I know at least one exeption: italian lira, they don't have decimal places
at all.

There is a guile list with currency names and currency symbols. May be
we could extend this list with the number of decimal places per currency
and other related information. The number of decimal places is e.g. also
needed for correct rounding in currency conversion. I will need this,
when I do some more work for EURO support, but this will not be before
July.
