[GitHub] [arrow-datafusion] WinkerDu commented on issue #2420: Type-coercion error with decimal type

WinkerDu commented on issue #2420:
URL: https://github.com/apache/arrow-datafusion/issues/2420#issuecomment-1115895149

   It seems `round` in df is an unary function with signature: `signature Uniform(1, [Float64, Float32])`
   The possible approach to solve this issue is:
   - Extends the `round` signature  to `one_of`
   - Introduce the new `round` expression implementation  in `math_expressions.rs`
   
   I can take this ticket as appropriate. @andygrove Can you assign this issue to me? Thank you.
