Xorshift random generators. The generators are implemented according to
the paper http://www.jstatsoft.org/v08/i14/paper by George Marsaglia.
You can use the
RandomGen instances to generate random numbers easily.
This module only exports the Random generator that matches your word size,
if you want to use a specific length, try Random.Xorshift.Int32 and
The type Xorshift is a wrapper around either Xorshift32 or Xorshift64, depending on the bit size of your system. The idea behind this is, that you may want to use this package as an uncomplicated, fast random generator, but repeated conversion between different word sizes are an absolute performance killer.
Thus, if you don't really care about the period of your random generator or
how long the result is, use the
Xorshift synonym, whenever possible.
