> Right now, if the operands on the decimal64 operations are columns with
> different scales, then we do not use the decimal64 vectorized version and
> fall back to HiveDecimal vectorized version of the operator. In this Jira, we
> will check if we can use decimal64 vectorized version, even if the scales are
> different.
