Mark Grover created HIVE-4174: --------------------------------- Summary: Round UDF converts BigInts to double Key: HIVE-4174 URL: https://issues.apache.org/jira/browse/HIVE-4174 Project: Hive Issue Type: Bug Components: UDF Affects Versions: 0.10.0 Reporter: Mark Grover Assignee: Mark Grover Fix For: 0.11.0
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} -- This message is automatically generated by JIRA.
