open override fun advanceToNextSubStream()

Positions the RNG at the beginning of its next substream

open operator fun div(x: Double): RVariableIfc
open operator fun div(other: RVariableIfc): RVariableIfc
Link copied to clipboard
open override fun instance(stream: RNStreamIfc): NormalRV

Makes a new instance. False allows the new instance to keep using the same underlying source of random numbers.

open fun pow(x: Double): RVariableIfc
Link copied to clipboard
open override fun resetStartStream()

The resetStartStream method will position the RNG at the beginning of its stream. This is the same location in the stream as assigned when the RNG was created and initialized.

open override fun resetStartSubStream()

Resets the position of the RNG at the start of the current substream
