Raymond Hettinger added the comment: A couple of thoughts: * It is okay to add a couple lines to the decimal module docs noting a Cpython specific implementation detail that it uses better than expected algorithms which can payoff nicely when used with very large numbers. * Mersenne prime examples and whatnot belong external to our docs. I usually put my recipes and examples on the ASPN Python Cookbook. http://code.activestate.com/recipes/langs/python/ ---------- nosy: +rhettinger _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue26256> _______________________________________
