[jira] [Created] (HIVE-20004) Wrong scale used by ConvertDecimal64ToDecimal results in incorrect results

Prasanth Jayachandran created HIVE-20004:
--------------------------------------------

             Summary: Wrong scale used by ConvertDecimal64ToDecimal results in incorrect results
                 Key: HIVE-20004
                 URL: https://issues.apache.org/jira/browse/HIVE-20004
             Project: Hive
          Issue Type: Bug
    Affects Versions: 3.1.0, 3.0.1, 4.0.0
            Reporter: Prasanth Jayachandran


ConvertDecimal64ToDecimal uses scale from output column vector which results in incorrect results.

Input: decimal(8,1) Output: decimal(9,2)

Input value: 963.8 gets converted to 96.38 which is wrong. The scale should not change this case (value should be 963.8 even after the conversion).
