      Description

      When the HIVE-2693 gets committed, users are going to see this behavior:

      hive> select cast(3.14 as decimal) from decimal_3 limit 1;
      3.140000000000000124344978758017532527446746826171875
      

      That's intuitively incorrect but is the case because 3.14 (double) is being converted to BigDecimal because of which there is a precision mismatch.

      We should consider creating a new literal for expressing constants of Decimal type as Gunther suggested in HIVE-2693.
