[jira] [Created] (SPARK-41047) round function with negative scale value runs failed

liyang created SPARK-41047:
------------------------------

             Summary: round function with negative scale value runs failed
                 Key: SPARK-41047
                 URL: https://issues.apache.org/jira/browse/SPARK-41047
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.2
            Reporter: liyang


Run this sql in spark-sql:    select round(1.233, -1); 
Error: org.apache.spark.sql.AnalysisException: Negative scale is not allowed: -1. You can use spark.sql.legacy.allowNegativeScaleOfDecimal=true to enable legacy mode to allow it.; 

But the document of round function implies that negative scale argument is acceptable.
