This should be possible. Try
as your distribution. (The extra parentheses arise
from a recent thread on using min/max.) For a
user-defined type such as your 128-bit integer, you'll
have to provide a template specialization of
std::numeric_limits before creating the distribution.
Make sure your base rng engine can actually cover at
least the integer range specified in
std::numeric_limits; boost::mt19937 should be good
enough for your purposes.
