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'
> Add FORMAT UDF
