[~jorgecarleitao] this is pretty stale and presumably you've duplicated this issue to arrow-rs and/or already resolved it, right?

> Currently, we have math functions declared as UDFs that while they can be evaluated against float32 and float64, their return type is fixed (float64).
> This issue is about extending the UDF interface to support generic return types (a function), so that developers (us included), can register UDFs or variable return types.
> There is a small overhead in this, since evaluating types now requires a function call, however, IMO this is still very small when compared to anything, as we are talking about plans. We can always apply some caching if needed.
