Remarks

The output sequence has been verified against the Mersenne Twister 64bit version reference output.

Long running tests have observed the expected minimum values Next 0 (0x0) from Core 0.000000000176224 and the expected maximum Next 2147483646 (0x7FFFFFFE) from Core 0.999999999743322.

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.
