Here's an example of some code in the standard library that would have benefited from the availability of `pow(x, n, m)` for arbitrary negative n: https://github.com/python/cpython/blob/e7a4bb554edb72fc6619d23241d59162d06f249a/Lib/_pydecimal.py#L957-L960 if self._exp >= 0: exp_hash = pow(10, self._exp, _PyHASH_MODULUS) else: exp_hash = pow(_PyHASH_10INV, -self._exp, _PyHASH_MODULUS) where: _PyHASH_10INV = pow(10, _PyHASH_MODULUS - 2, _PyHASH_MODULUS) With the proposed addition, that just becomes `pow(10, self._exp, _PyHASH_MODULUS)`, and the `_PyHASH_10INV` constant isn't needed any more. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36027> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
