> previous https://issues.apache.org/jira/browse/HIVE-8389 assumes that
> we have predicate: ((UDFToDouble(key) > UDFToDouble(80)) and (UDFToDouble(key) < UDFToDouble(100))) for example.
> This does not work for the case when we have predicate: ((UDFToDouble(key) > 80.0) and (UDFToDouble(key) < 100.0))
