Just as the comment suggest : {quote}Those expressions are supposed to be in the same data type, and also the return type.{quote} But in code, function f was casted to function signature: {code}(Numeric[n.JvmType], n.JvmType, n.JvmType) => Int{code} I thought it as a typo and the correct should be: {code}(Numeric[n.JvmType], n.JvmType, n.JvmType) => n.JvmType{code} was: In sql/catalyst/org/apache/spark/sql/catalyst/expressions.scala protected final def n2 ( i: Row, e1: Expression, e2: Expression, f: ((Numeric[Any], Any, Any) => Any)): Any is intended to do computations for Numeric add/Minus/Multipy.
