Package: pari-stable
Version: 2.7.3
The (excellent) examples in the documentation no longer work as explained, probably because of changes to random() or setrand(). I get [51933523800] for the first example rather than [35023733690], and [614843249908471736] instead of [265174753892462432] on the second.
If you're going to update the examples, though, I suggest taking the opportunity to use the 2.6.0 function randomprime(), which has the nice side effect of making the examples work on 100% instead of ~90% of random seeds:
p = randomprime([10^29, 10^30]);
q = randomprime([10^29, 10^30]); N = p*q;
