I believe there is a numeric error in big_integer. I am working to isolate it to a single operation. I can find the error now because the library is fast enough to run one of my sims. I get a different value when running with rational<big_integer> then with any of these choices (which give identical results) rational<long long> rational<big_integer (cln)> rational<big_integer (gmp)> cln::cl_RA Not that it is much use but the wrong answers are: Inonsistent Value: 38485535445/562949953421312 6375930541/562949953421312 Consistent Value: 42780502741/562949953421312 10670897837/562949953421312 Again, I'll try to narrow down the exact point where things go wrong but it might take a while.
