Random number generator (included): Difference between revisions

<code>random</code> uses Richard Brent's [http://wwwmaths.anu.edu.au/~brent/random.html xorgens]. It's a member of the xorshift class of PRNGs and provides good, fast pseudorandomness (passing the big crush test, unlike the Mersenne twister), but it is not cryptographically strong. As implemented in Pari, its period is "at least <math>2^{4096}-1".</math>
