> 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.

> 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}
