Public bug reported:

We're trying to integrate the invoices of the account module with
another platform, but we've been having many problems related to the
calculation of totals and subtotals.

I've reproduced the problem with a very simple invoice on a clean
database, with just the base modules + account installed. Attached is a
screenshot, but the situation is simple: we have a product with a price
of 5.35€ and a 50% discount, so OpenERP calculates a line subtotal of
2.67€.

Unfortunately, this is not a reasonable value, since 5.35/2 is 2.675€,
which should be - and is on the platform we're trying to integrate -
2.68€.

(You can check on WolframAlpha:
http://www.wolframalpha.com/input/?i=%2850%25+of+5.35%29+rounded+to+3+significant+digits)

While the difference seems small, the accumulation of such errors is
enough to cause problems, especially since accounting and payments are
involved.
