**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** We would like to compute a power function (like `2**4` = `2 * 2 * 2 * 2`) in datafusion @matthewmturner asks for it here: https://github.com/apache/arrow-datafusion/issues/147#issuecomment-1001223018 **Describe the solution you'd like** Implement the `power` function as described in https://www.postgresql.org/docs/14/functions-math.html ``` power ( a numeric, b numeric ) → numeric power ( a double precision, b double precision ) → double precision a raised to the power of b power(9, 3) → 729 ``` **Describe alternatives you've considered** It may also be interesting to investigate adding support for `a**b` as another way to write the same thing **Additional context** This is probably a good ticket to learn about the datafusion codebase and its function implementations -- one could follow the example of one of the existing functions in https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_plan/functions.rs -- This is an automated message from the Apache Git Service.
