    Description

      when we do avg aggregation for decimal type:
      hive wiil update the precision of the avg result.
      e.g: Avg(decimal(30,10)), the result will be cast to decimal(34, 14)
      so, carbon should keep the sync with hive, also need to improve the precision
      by scaling up.
