Raymond Hettinger added the comment: The next question is whether we care about that 1 ULP in the context of the random number calculations which already involve multi-step chains that aren't favorable to retaining precision:
s + (1.0 + s * s) ** 0.5 ainv = (2.0 * alpha - 1.0) ** 0.5 bbb = alpha - LOG4 ccc = alpha + ainv g2rad = (-2.0 * _log(1.0 - random())) ** 0.5 z = _cos(x2pi) * g2rad self.gauss_next = _sin(x2pi) * g2rad stddev = (sqsum/n - avg*avg) ** 0.5 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24059> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
