I see no use of 128-bit ints in the CPython core. Advice: forget it. int64_t and uint64_t are required by C99, and are used many places in the core. Advice: use freely. Note that if tables of "odd part mod 2**64" and "number of trailing zeroes" are used up through 67, then factorials up through 25! are trivially computed via Fodd[i] << Fntz[i] (at 26, the odd part no longer fits in 64 bits) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37295> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
