Subject [SQL] Return Type of Round Func
Date Tue, 04 Jul 2017 09:22:56 GMT
Hi all,

I have a question regarding the round() function, which was developed long
time ago as SPARK-8159. Currently, the return type is exactly as the input
type. That is reasonable, but does not match with Hive. As I understand,
Hive produces either double or decimal as output (see here
<https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF> for
details).

I know that some functions (e.g., ceil and floor) were updated to match the
behavior of Hive (e.g., return types). Shouldn't it be the same here?

Best,
Anton
