Scala functional programming gymnastics

Question

I am trying to do the following in as little code as possible and as functionally as possible:

def restrict(floor : Option[Double], cap : Option[Double], amt : D         


        

Answer 1

This is another way to fix Landei's first answer

def restrict(floor : Option[Double], cap : Option[Double], amt : Double) : Double = {
  val chopBottom = (floor.getOrElse(amt) max amt) 
  chopBottom min cap.getOrElse(chopBottom)
}
