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.
