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
