> Chen Chun pointed out on the hive-user mailing list that round() in Hive 0.10
> returns
> {code}
> select round(cast(1234560 as BIGINT)), round(cast(12345670 as BIGINT)) from
> test limit 1;
> //hive 0.10
> 1234560.0 1.234567E7
> {code}
> This is not consistent with
> MySQL(http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html#function_round)
> which quotes
> {code}
> The return type is the same type as that of the first argument (assuming that
> it is integer, double, or decimal). This means that for an integer argument,
> the result is an integer (no decimal places)
> {code}
