Change subject: IMPALA-3436: Return a decimal when rounding a double ...................................................................... Patch Set 3: (1 comment) http://gerrit.cloudera.org:8080/#/c/8398/3/common/function-registry/impala_functions.py File common/function-registry/impala_functions.py: http://gerrit.cloudera.org:8080/#/c/8398/3/common/function-registry/impala_functions.py@285 PS3, Line 285: [['round_v1','dround_v1'], > I agree could be legit uses cases for non-const precisions. Just to clarify. I think what Alex is saying is that the proper fix is so that the round function looks like this: round(double, int) -> decimal AND the second argument can be non-const. The limitation in this patch is that the second arg must be const. Alex is also saying that there should not exist a round() function that returns a double in decimal v2 (and I agree with this). -- To view, visit http://gerrit.cloudera.org:8080/8398 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I240ec70da7996bbfefcf6438eba4dff8d33d7bd6 Gerrit-Change-Number: 8398 Gerrit-PatchSet: 3 Gerrit-Owner: Taras Bobrovytsky <tbobrovyt...@cloudera.com> Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Taras Bobrovytsky <tbobrovyt...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Comment-Date: Thu, 16 Nov 2017 06:15:30 +0000 Gerrit-HasComments: Yes
