Previously @thirtiseven helped with benchmarking, like this NVIDIA/spark-rapids#10917 (comment). @thirtiseven can you run such benchmark again on this please? Thanks. |

This implements a casting operation from floating point values to decimal values, following the rules of Apache Spark. The casting function also returns an additional boolean flag indicating if there was any failures with any input rows, leaving the caller to make decision whether to accept the result as-is or raise an exception.
