    I felt that there are too many extremely unecessarily long examples of xorshift32 implementations out there, with lots of fluff around the outside. It's a very nice and simple little PRNG and this is all the code you need to turn it into a unit interval (i.e the type and range you get from Math.random()): (x>>>0) * 2**-32. This conversion method is far from perfect and results in some bias, but so does the PRNG itself...
