---------------------------------------
Summary: 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
Reporter: Jonathan Leech
Priority: Minor
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.
