Detailed Description

A random number generator combining several techniques by George Marsaglia (1999; internet posting).

Here is an excerpt from the posting describing this generator: For the super cautious, (KISS+SWB) in an expression would provide a random 32-bit integer from a sequence with period > 2⁷⁷⁰⁰, and would only add some 300 nanoseconds to the computing time for that expression.
