Hello
That may not be needed , Since the numbers here are much smaller and more
importantly positive. And Hence the help of such a generic library is not be
needed. Besides i have most of the code ready, i just have to port it into
boost specific format. So I am  looking for the community's interest in the
proposal.
Thank you
