-------------------------------------
[~beliefer] do you have time to take a look?
> SPARK-42045 is incomplete in supporting ANSI_MODE fro round() and bround()
> --------------------------------------------------------------------------
>
> Key: SPARK-42546
> URL: https://issues.apache.org/jira/browse/SPARK-42546
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.3.2, 3.4.0
> Reporter: Serge Rielau
> Priority: Major
>
> under ANSI mode SPARK-42045 added error conditions insetad of silent
> overflows for edge cases in round() and bround().
> However it appears this fix works only for the INT data type. Trying it on a
> e.g. SMALLINT the function still returns wrong results:
> {code:java}
> spark-sql> select round(2147483647, -1);
> [ARITHMETIC_OVERFLOW] Overflow. If necessary set "spark.sql.ansi.enabled" to
> "false" to bypass this error.{code}
> {code:java}
> spark-sql> select round(127y, -1);
> -126 {code}
