Remarks

For more information see xoshiro / xoroshiro generators and the PRNG shootout.

Long running tests have observed the minimum values Next 0 (0x0) for Core 0.000000000085086 and the maximum Next 2147483646 (0x7FFFFFFE) from Core 0.999999999706094.

A Core 0.0 is unlikely to be seen because there is a vanishing chance of seeing the limit values of 0x0000000000000000 and 0xFFFFFFFFFFFFFFFF in a flat random distribution of 64 bit values.
