> When inserting float-point numbers to a table, the values displayed on beeline or jdbc
are with different precision.
> How to reproduce:
> {noformat}
> 0: jdbc:hive2://localhost:10000> create table decimals (f float, af array<float>,
d double, ad array<double>) stored as parquet;
> No rows affected (0.294 seconds)
> 0: jdbc:hive2://localhost:10000> insert into table decimals select 1.10058, array(cast(1.10058
as float)), 2.0133, array(2.0133) from dummy limit 1;
> ...
> No rows affected (20.089 seconds)
> 0: jdbc:hive2://localhost:10000> select f, af, af[0], d, ad[0] from decimals;
> +---------------------+------------+---------------------+---------+---------+--+
> |          f          |     af     |         _c2         |    d    |   _c4   |
> +---------------------+------------+---------------------+---------+---------+--+
> | 1.1005799770355225  | [1.10058]  | 1.1005799770355225  | 2.0133  | 2.0133  |
> +---------------------+------------+---------------------+---------+---------+--+
> {noformat}
> When displaying arrays, the values are displayed correctly, but if I print a specific
element, it is then displayed with more decimal positions.
