Percent is an opaque Double value

Percent can be created with method constructors on primitives

 3.Percent.tp     // Prints: 3.0%
 3.14.Percent.tp  // Prints: 3.14%

Bi-Directional Function

TwoWayFun allows to convert value to some type and back

It is used in two way binded collections

  val intToChar: TwoWayFun[Int,Char] = TwoWayFun(i => ('A' + i).toChar, _ - 'A')

  val list:  Idx.M[Int] = Stream(0, 2, 4).toBuffer
  val view:  Idx.M[Char] = list.twoWay_^(intToChar)

  list.~.tp     // Prints ~(0, 2, 4)
  view.~.tp     // Prints ~(A, C, E)

  view(1) = 'Z' // Note, only second collection is updated, but both are changed

  list.~.tp     // Prints ~(0, 25, 4)
  view.~.tp     // Prints ~(A, Z, E)
