This module contains a 64 bit Xorshift random generator. Use this if you
need a 64 bit random generator, usually
Xorshift itself is a good choice
for your platform. This generator has a period of 2^64-1 bits if
initialized with a value different from 0.
Xorshift generator with 64 bits. This Xorshift generator uses first a left shift, then a right shift and again a left shift. It uses the parameters 13, 7 and 17. See the paper for more details on how the parameters affect the generation of random numbers.
The generator has a periode of 2^64-1, please notice that the generator has to be initialized with a value different from 0, elseway all future values will be zero as well.
Please notice, that the function
split is not implemented and will result
in a runtime error.
Generate a new
Xorshift64 generator. This is essentially a wrapper around
