If the number of digits in the result exceeds the number of digits that the implementation supports, the result is truncated or rounded in an ·implementation-defined· manner." Consider the query "1 div 3". Certainly a result of 0.333333333333333333 (18 digits) would be permitted. Would a value of 0.333333333333333 (15 digits) be permitted as well? Michael Kay has argued: "The first sentence must be read in the context of the second, which creates a relationship between the number of digits in the result of decimal division and the number of digits supported by the xs:decimal data type. The latter must be at least 18, and I believe that the result of division should therefore not truncate or round unless it requires more than 18 digits." This question is being raised based on several test cases, as reported on the XML Query Test Suite in [1] and [2].
