We did it - at least partial in 
https://bugzilla.gnome.org/show_bug.cgi?id=628903 .
One could subsume this as rounding errors, which can have several reasons:

Which rounding method is used and which should be used? See 
http://en.wikipedia.org/wiki/Rounding . In short important are 
traditional "round half away from zero" and IEEE's  "round half to even".
Are there governmental rules, which should be used like European Commission 
report "The Introduction of the Euro and the Rounding of Currency Amounts" 
[http://ec.europa.eu/economy_finance/publications/publication1224_en.pdf]?
So for a short time there was som wrong rounding, which should be fixed since 
2.3.16.

The next question is in Bug 504954 - Where and how should the rounding happen 
in invoices with VAT? This bug is still open as nobody had time to work on 
it.
