Hello,
I am wondering if 1.40.0 has solved the bugs reported and fixed for the
random numbers package.
The below message plus the discussions in the Archives don't give
the impression that the package is in a good shape, but maybe this
is now history, and it were only some central bugs that are fixed no.

In any case, uniform_int<> and uniform_smallint<> are quite broken, if they can't be uniform for such a small range.
They are (quite broken).

Unfortunately, Jens Maurer has stopped maintaining Boost.Random, and random numbers are tricky enough so noone else with the sufficient expertise has taken over.
Well, I'll use tr1::random from now on, but I think there should be at least a big red warning in the documentation website about this, specially if no one will address these problems in the near future...
uniform_int is now fixed in the trunk. In Christ, Steven Watanabe _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Most of the fixes that I've made are in 1.40. uniform_int ought to be completely correct now. The fixes that were not merged are just warning suppression and extra asserts. In Christ, Steven Watanabe
