Julian Hyde commented on PHOENIX-2048:

By the way, if you don't have an Oracle instance, this is an easy way to get one using Docker:

> 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.
