    [ https://issues.apache.org/jira/browse/HIVE-2694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13180747#comment-13180747 ] 

Carl Steinbach commented on HIVE-2694:
--------------------------------------

Ref: http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_format

Formats the number X to a format like '#,###,###.##', rounded to D decimal places, and returns the result as a string. If D is 0, the result has no decimal point or fractional part.

mysql> SELECT FORMAT(12332.123456, 4);
        -> '12,332.1235'
mysql> SELECT FORMAT(12332.1,4);
        -> '12,332.1000'
mysql> SELECT FORMAT(12332.2,0);
        -> '12,332'
