Sathiya Kumar updated SPARK-37475:
----------------------------------
Description:
This feature is proposed in the PR : https://github.com/apache/spark/pull/34593
Currently we support Decimal RoundingModes : HALF_UP (round) and HALF_EVEN
(bround). But we have use cases that needs RoundingMode.UP and
RoundingMode.DOWN.
[https://stackoverflow.com/questions/34888419/round-down-double-in-spark/40476117]
[https://stackoverflow.com/questions/54683066/is-there-a-rounddown-function-in-sql-as-there-is-in-excel]
[https://stackoverflow.com/questions/48279641/oracle-sql-round-half]
Floor and Ceil functions helps to do this but it doesn't support the position
of the rounding. Adding scale parameter to the functions would help us control
the rounding positions.
Snowflake supports `scale` parameter to `floor`/`ceil` :
{code:java}
FLOOR( <input_expr> [, <scale_expr> ] ){code}
