Chen Chun updated HIVE-4174:
----------------------------
Release Note: The change makes the return type of round function be 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).
Hadoop Flags: Incompatible change
Status: Patch Available (was: Open)
> Round UDF converts BigInts to double

> 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}
