### Is your feature request related to a problem or challenge? Part of https://github.com/apache/datafusion/issues/15914 Given the importantance of spark functions in general, we are consolidating / adding spark compatible functions in the `datafusion-spark` crate in DataFusion: https://github.com/apache/datafusion/tree/main/datafusion/spark This ticket is part of a series of ticket to fill out the set of spark compatible functions in DataFusion ### Describe the solution you'd like Implement the function listed above in the `datafusion-spark` crate ### Describe alternatives you've considered 1. Add the relevant function here: https://github.com/apache/datafusion/tree/main/datafusion/spark/src/function/math 2. Add tests. Instructions are here: https://github.com/apache/datafusion/blob/main/datafusion/spark/README.md ### Examples to follow: * The existing `expm1` implementation : https://github.com/apache/datafusion/blob/main/datafusion/spark/src/function/math/expm1.rs * COmet implementation here: https://github.com/apache/datafusion-comet/blob/main/native/spark-expr/src/math_funcs * Sail implementation here: https://github.com/lakehq/sail/blob/4144d9a53d3f1ef447b3d2ce9afa9030906de640/crates/sail-plan/src/function/scalar/math.rs#L404 You can also find the corresponding datafusion implementations in the corresponding file here: https://github.com/apache/datafusion/tree/main/datafusion/functions/src (it would be ok to call into these implementations if they are the same as the spark implementation) ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
