Remarks

For the author's description see: ISAAC: a fast cryptographic random number generator. The algorithm also has a Wikipedia article.

Long running tests have observed the expected minimum values Next 0 (0x0) and Core 0.0 and the expected maximum Next 2147483646 (0x7FFFFFFE) from Core 0.999999999534339.
