Csaba Skrabak commented on PHOENIX-2048: ---------------------------------------- Found nothing about rounding in the Oracle online documentation. We tried in Live SQL, it rounded with HALF_UP. Still not sure if there is a config value in Oracle that changes rounding mode. So the question is the same. Do you think we need to do this in a configurable way? > change to_char() function to use HALF_UP rounding mode > ------------------------------------------------------ > > Key: PHOENIX-2048 > URL: https://issues.apache.org/jira/browse/PHOENIX-2048 > Project: Phoenix > Issue Type: Improvement > Affects Versions: verify > Reporter: Jonathan Leech > Priority: Minor > Fix For: 4.12.0 > > Attachments: phoenix-2048.patch > > > to_char() function uses the default rounding mode in java DecimalFormat, > which is a strange one called HALF_EVEN, which rounds a '5' in the last > position either up or down depending on the preceding digit. > Change it to HALF_UP so it rounds the same way as the round() function does, > or provide a way to override the behavior; e.g. globally or as a client > config, or an argument to the to_char() function. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
