Hello, Would there be any interest in a modified "rational" class template/header that optionally allows for an exception be generated if there is under/overflow during any of the operations? I have been developing such a template, where the new defaulted bool template parameter would generate the class exactly as before to preserve the original stable implementation, and to support unlimited-precision integer where over/underflow would not be possible. Setting the new template parameter to true, however would generate code that adds the over/underflow checking. I have also generated new test driver code (BTW test code referenced by the documentation does not appear to exist, or at least the link is broken). rational.hpp has been around and stable for quite some time, so there may be a desire to keep it unchanged, but its original function (and indeed its original source code) can be maintained through the template system. If such a class were to be included in boost, what would be the best submission method?
