-----------------------------------------------------------

Review request for hive and Ashutosh Chauhan.


Repository: hive-git


Description
-------

Overload trunc() function to accept numbers.

Now trunc() will accept date or number type arguments and it will behave as below

trunc(date, fmt) / trunc(N,D) - Returns

If input is date returns date with the time portion of the day truncated to the unit specified by the format model fmt. 
If you omit fmt, then date is truncated to "the nearest day. It now only supports 'MONTH'/'MON'/'MM' and 'YEAR'/'YYYY'/'YY' as format.

If input is a number group returns N truncated to D decimal places. If D is omitted, then N is truncated to 0 places.
D can be negative to truncate (make zero) D digits left of the decimal point.

Thanks for the review. I will add tests as part of this JIRA HIVE-15325

    I think it'll be good to add tests with negative numbers as well as no-op (e.g. select trunc (12.34, 100).

Review request for hive and Ashutosh Chauhan.


Changes
-------

Updated diff like, now trun() function will accept non constants as scale argument. Updated test cases also. All tests are pass in local environment.


Repository: hive-git


Description
-------

Overload trunc() function to accept numbers.

Now trunc() will accept date or number type arguments and it will behave as below

trunc(date, fmt) / trunc(N,D) - Returns

If input is date returns date with the time portion of the day truncated to the unit specified by the format model fmt. 
If you omit fmt, then date is truncated to "the nearest day. It now only supports 'MONTH'/'MON'/'MM' and 'YEAR'/'YYYY'/'YY' as format.

If input is a number group returns N truncated to D decimal places. If D is omitted, then N is truncated to 0 places.
D can be negative to truncate (make zero) D digits left of the decimal point.
