    This inner class defines comparison operators available for T.

    This inner class defines comparison operators available for T.

    It can't extend AnyVal because it is not a top-level class or a member of a statically accessible object.

  2. def compare(x: Double, y: Double): Int

    Returns an integer whose sign communicates how x compares to y.

    Returns an integer whose sign communicates how x compares to y.

    The result sign has the following meaning:

    • negative if x < y
    • positive if x > y
    • zero otherwise (if x == y)

    Example:
    1. case class Pair(a: Int, b: Int)
      
      val pairOrdering = Ordering.by[Pair, Int](_.a)

  20. def orElseBy[S](f: (Double) => S)(implicit ord: Ordering[S]): Ordering[Double]

    Given f, a function from T into S, creates an Ordering[T] whose compare function returns the result of this Ordering's compare function, if it is non-zero, or else a result equivalent to:

    Given f, a function from T into S, creates an Ordering[T] whose compare function returns the result of this Ordering's compare function, if it is non-zero, or else a result equivalent to:

    Ordering[S].compare(f(x), f(y))

    This function is equivalent to passing the result of Ordering.by(f) to orElse.
