Ersa-tech opened a new issue, #7002: URL: https://github.com/apache/datafusion-comet/issues/7002
With `spark.sql.legacy.allowNegativeScaleOfDecimal=true`, `CAST(CAST(c * 1E2 AS TIMESTAMP) AS LONG)` returns `-45600`, `0`, `12300` in Spark. Comet panics in `10_i128.pow(scale as u32)` with `attempt to exponentiate with overflow`. `CometCast.canCastFromDecimal` reports the cast as compatible for any scale. The decimal-to-string path already checks that setting. This predates and is unchanged by #6969; found in review there. -- This is an automated message from the Apache Git Service.
