Random

case class Random(stream: Int) extends Product with Serializable

This class generates random real numbers in the range (0, 1). It is a Multiplicative Linear Congruential Generator (MLCG) shown to have statistical properties adequate for simple simulations (x = ax % m). In case a better generator is needed, a Multiple Recursive Generator (MRG) should be used.

stream

the random number stream index
