Ashutosh Chauhan commented on HIVE-3820:
----------------------------------------
Patch looks good. You have chosen D. I wonder if other systems allow d or BD as
well. Do you know if sql standard says anything for it?
> Consider creating a literal like "D" or "BD" for representing Decimal type
> constants

> When the HIVE-2693 gets committed, users are going to see this behavior:
> {code}
> hive> select cast(3.14 as decimal) from decimal_3 limit 1;
> 3.140000000000000124344978758017532527446746826171875
> {code}
> 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.
