How to pass an object to a method in Scala

Question

How can I pass the reference of an object to method in Scala? E.g. I want this to compile

object Constants {
  val constantA:Double = ???
}


def calc(number         


        

Answer 1

Look at the synthax of your method definition: what does your calc method produce ? Unit ? Int ? I suggest that you review the basics of the Scala synthax first
