Technical Notes
By default, the Built-In-Function RANDOM_NUM_GENERATOR always returns a random number between 0 and 1. For advanced users, it also provides 100 independent streams of random numbers, where drawing a random number from one stream does not affect the sequence of random numbers drawn from a different stream. Each stream is referenced using an optional "stream index" in the range [0,99], inclusive. If no stream index is supplied, then stream 0 is used by default.
By default, the Built-In-Function RANDOM_NUM_GENERATOR seeds (i.e. initializes) each stream from the current system time the first time the stream is referenced. For advanced users, it also accepts an optional seed value which is used to seed (i.e. initialize) a stream. This is useful if you wish to repeat the same sequence of random numbers many times.
