Quick overview of the update: the original usage and code of the template class remains mostly as before, ie boost::rational<int> RationalVar; should work as in the original version. Adding 'true' as a second template parameter, however, allows an exception to be raised if an operation with a class variable results in a value that can't accurately be represented

I haven't looked at anything else, but I dislike using true/false as the template argument. I'd prefer meaningful names. _____ Rob Stewart robert.stewart@sig.com Software Engineer using std::disclaimer; Dev Tools & Components Susquehanna International Group, LLP http://www.sig.com ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.
