> In sql/catalyst/org/apache/spark/sql/catalyst/expressions.scala
> {code}protected final def n2 ( i: Row, e1: Expression, e2: Expression, f: ((Numeric[Any], Any, Any) => Any)): Any  {code}
> is intended  to do computations for Numeric add/Minus/Multipy.
> 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}
