Tracking the disussion on n1774 'Big integer library proposal for C++0x' I see there is a lot of controversy about it, and it will probably need much tweaking before (if ever) it is accepted. Wouldn't that be a good idea to have a big integer added to boost so that we can create a 'working practice' before anything gets standarised? I have some preliminary source code, some spare time, and would volunteer to work on it if there's enough interest. cheers, M.

Yes, absolutely!

That would be great -- please do. Jeff

If boost is serious about big number support, then we should probably be looking at GMP at http://swox.com/gmp/ ... if we haven't already.

Here here - I'd be much obliged for such a thing, again please do. Cheers, -- Manfred Doudar MetOcean Engineers 29 April, 2005

It would be very great :) I have been working on a big integer library, and already showed a preliminary version here at boost, but I haven't had the time to really finish it. I'm graduating in a month, and hope to have some spare time then. See for the initial discussion http://lists.boost.org/MailArchives/boost/msg04191.php and a recent discussion http://lists.boost.org/MailArchives/boost/msg79916.php.
I have some preliminary source code, some spare time, and would volunteer to work on it if there's enough interest.
Of course, don't let previous work stand in the way. I would love to hear new insights, so that the best possible proposal is made. best regards, Richard Peters

Yes, very much so!

I think there is a lot of interest, so I think a Boost submission would get a lot of attension. --Beman

Hi, I missed that too: I'm also VERY, VERY, VERY INTERESTED in having this library in Boost. For example, for one application I've written (a strong random generator for constraint satisfaction problems) the missing Big integer library is now a big problem: The one I used is not standard-compliant, and, though I fixed the syntactical problems, broke down on a 64 bit platform. So I have to replace this library. Orginally, I wanted to use GMP instead, but then their warnings about "miscompilation" and especially that "For GMP 4.1.4, we recommend that you use GCC 3.3.x or older" made me change my mind --- I guess this wouldn't happen with Boost! So I'm in the situation now that this (once working) random generator has to wait for a big integer library (I mean, of high quality -- that's what I expect from Boost). If a big integer library would be available from Boost, I would use it in most of my applications and libraries. Oliver

I think it is a good idea. The limitation of size for integers can be a real pb in certain programs. I actually would like to participate in the developement of this class, if my help can be usefull. Olivier

The replies indicated some interest in arbitrary long integer / arbitrary precision arithmetic among Boost users and developers. Today I got a call for participation in the `"many digits" friendly competition 2005' organized by Radboud University, Nijmegen, The Netherlands. To quote from the call for participation: In the Institute for Computing and Information Sciences at Radboud University Nijmegen we will organise a demo/benchmark session for investigating the state of the art in the various implementations of exact real arithmetic. The event will be held on 3-4 October 2005, in conjunction with the Small TYPES workshop on Constructive analysis, types and exact real numbers <http://www.cs.ru.nl/fnds/typesreal/>. I don't have time to pursue this myself but those interested in the topic might also be interested in this event - maybe not with an own submission, but to learn from the experiences others made while implementing arbitrary precision arithmetic. The complete call for participation is available at <url:http://www.cs.ru.nl/~milad/manydigits/CFPar.txt>.
