Andy Jefferson commented on JDO-643:
------------------------------------
+1 on this. Perhaps we could at least get agreement that this is how it ought
to be and I can change the RI and any test accordingly.
> 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
> Assignee: Michael Bouschen
> Fix For: JDO 3 maintenance release 1
>
>
> 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.
