Subject [jira] Created: (JDO-643) avg return type
Date Mon, 12 Oct 2009 10:45:31 GMT
avg return type

                 Key: JDO-643
                 URL: https://issues.apache.org/jira/browse/JDO-643
             Project: JDO
          Issue Type: Bug
          Components: specification
    Affects Versions: JDO 2 maintenance release 2
            Reporter: Guido Anzuoni

Aggregate type specification at page 175 claims that avg(expression) return type is the same
of the enclosed expression.
This is wrong from a strictly mathematical point of view.
In fact, if you select an avg on an int field member the result is truncated.
The result type should always be double.
