Here the oversight was to round internally to 4 d.p. and THEN apply the euro rounding rule. The name of the package is not relevant, as the fact that this failure as not found in the accreditation tests means that in theory any of the 25 accredited packages could have similar defects. Check your own accounts package and contact your supplier if you find the problem. You could also try EUR 955.06 into DEM 755.41 and EUR 938.14 into FRF
It is easy to create other test cases to find similar problems with other currencies and with triangulation.
Not just a freakish 4 d.p. problem; cases can be created for 5, 6, 7 d.p. and thatís with euro amounts up to 1000 euro.
