Sathiya Kumar updated SPARK-37324:
----------------------------------
Description:
Currently we support only Decimal RoundingModes : HALF_UP (round) and HALF_EVEN
(bround). But we have use cases that needs RoundingMode.UP and
RoundingMode.DOWN. In our projects we use UDF, i also see few people do complex
operations to do the same with spark native methods.

[https://stackoverflow.com/questions/48279641/oracle-sql-round-half]
Opening support for the other rounding modes might interest a lot of use cases.
*SAP Hana Sql ROUND function does it :*
{code:java}
ROUND(<number> [, <position> [, <rounding_mode>]]){code}

*Sql Server does something similar to this* :
{code:java}
ROUND ( numeric_expression , length [ ,function ] ){code}
