Oh dear. I can only hope that they never represent my money - unless
you want to round upwards.
The best advice I can offer is: don't use floating point to represent
money. Use integer arithmetic only (on the cents/pence/euro cents),
and guard against overflows.
A compromise is to use erlang:round() instead of trunc and you
*probably* be OK... although I reserve the right to take that back if
it ever goes wrong.
