Type Members

1.  final case class Coin[A, B](prob: Ex[A], gen: Random)(implicit num: NumDouble[A] { type Boolean = B }, default: HasDefault[B]) extends Ex[B] with Act with ProductWithAdjuncts with Product with Serializable

   A random boolean with a given probability.

   A random boolean with a given probability. If prob is zero, the output will always be false, if prob is one, the output will always be true, if prob is 0.5, the likelihood of false and true is equal.

   This is both an expression and an action. The action draws a new random number, the expression reports the last drawn value.

   Example:

   val gen = Random()
   val coin = gen.coin(0.4)
   Act(
     coin, // draw new number
     PrintLn("Random coin (slightly favouring false): " ++ coin.toStr)  // print current value
   )

2.  final case class Range[A](lo: Ex[A], hi: Ex[A], gen: Random)(implicit num: Num[A]) extends Ex[A] with Act with ProductWithAdjuncts with Product with Serializable

   A random number between a given lo and a given hi boundary.

   A random number between a given lo and a given hi boundary. The boundaries are inclusive for integer numbers. For floating point numbers, the hi bound is exclusive.

   This is both an expression and an action. The action draws a new random number, the expression reports the last drawn value.

   Example:

   val gen = Random()
   val r1to10 = gen.range(1, 10)
   Act(
     r1to10, // draw new number
     PrintLn("Random number (1 to 10): " ++ r1to10.toStr)  // print current value
   )

3.  final case class Until[A](hi: Ex[A], gen: Random)(implicit num: Num[A]) extends Ex[A] with Act with ProductWithAdjuncts with Product with Serializable

   A random number between zero (inclusive) and a given hi boundary (exclusive).

   A random number between zero (inclusive) and a given hi boundary (exclusive). hi may be negative, but it must not be zero.

   This is both an expression and an action. The action draws a new random number, the expression reports the last drawn value.

   Example:

   val gen = Random()
   val r100 = gen.until(100)
   Act(
     r100, // draw new number
     PrintLn("Random number: " ++ r100.toStr)  // print current value
   )
