My proposal is, for `round/ceil(input, scale)` if `scale != 0`, the expected input type should be decimal type, and the type coercion framework should cast int, double, etc. to decimal type. The result type can be ``` case DecimalType.Fixed(p, s) => if (scale < 0) { DecimalType(math.max(p, 1 - scala), 0) } else { DecimalType(p, math.min(s, scale)) } ``` -- This is an automated message from the Apache Git Service.
