-------------------------------------
[~sershe] I think that ticket is HIVE-13098. Based on the size of that WIP
patch, I think I'll put this on hold for now.
> An exception should be raised if the result is outside the range of decimal

> If the result cannot be represented exactly in the result type, then whether
> it is rounded
> or truncated is implementation-defined. An exception condition is raised if
> the result is
> outside the range of numeric values of the result type, or if the arithmetic
> operation
> is not defined for the operands.
> {noformat}
> Currently Hive is returning NULL instead of throwing an exception if the
> result is out of range, eg.:
> {code}
> > select 1000000000000000000.000001*1000000000000000000.000001;
