So far as I see, ERROR is not one of two legal results, but the only
legal result for all numeric functions using decimal, integer,
nonPositiveInteger, nonNegativeInteger, positiveInteger and
negativeInteger. This results in "passed" tests for all non- or
minimal-conforming query engines and "failed" tests for conforming
engines! This seems not to be fair and makes the (NIST)results unable to
If you need a tool to calculate the correct results for these tests, I
suggest using IPSI-XQ, which supports decimal und integer values with
arbitrary length since its very first release! ;-)
