> Currently Hive uses a default decimal type info instance to associate with a
> decimal constant in the expression tree. To precisely determine the
> precision/scale of the expression result requires more accurate
> precision/scale of the type of the decimal constant. Thus, Hive uses a
> precision/scale of the constant for the type info instance. As an example,
> the following is not desirable:
> {code}
> hive> create table mytable as select 3.14BD as t from person_age limit 1;
> hive> desc mytable;
> OK
> t decimal(65,30) None
> Time taken: 0.08 seconds, Fetched: 1 row(s)
> {code}
> instead, the precision/scale for t above should be (3, 2).
