Github user fhueske commented on the issue:

    I got a bit lost in the discussion, but if I understood @wuchong's options right, I prefer
the first option. Automatically converting `DECIMAL` to `DOUBLE` can result in rounding errors.
However, the whole purpose of `DECIMAL` is to provide exact results. So I would rather request
an explicit cast than computing unexpected imprecise results.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
