case class Random3(stream: Int = 0) extends RNG with Product with Serializable

The Random3 class generates random real numbers in the range (0, 1). It implements, using 64-bit integers (Int's), the 'MINSTD' generator, which is a multiplicative Linear Congruential Generator (LCG). These generators were commonly used in the last century.
x_i = a x_i-1 % m

stream

the random number stream index
