Detailed Description

The congruential random number generator by George Marsaglia (1999; internet posting).

This RNG is fast and has a very low memory footprint. Here is an excerpt from the posting describing this generator: CONG is a congruential generator with the widely used 69069 as multiplier: x(n)=69069x(n-1)+1234567. It has period 2³². The leading half of its 32 bits seem to pass all tests, but bits in the last half are too regular.
