I agree this doesn't occur in 3.10, but think Raymond pasted wrong outputs. Here: Python 3.10.0a4+ (heads/master:64fc105b2d, Jan 28 2021, 15:31:11) [MSC v.1928 64 bit (AMD64)] on win32 >>> x = 0.6102683302836215 >>> y1 = 0.7906090004346522 >>> y2 = y1 + 1e-16 >>> from math import hypot >>> hypot(x, y1) 0.998744224772008 >>> hypot(x, y2) 0.9987442247720081 Those both appear to be the results "as if" computed to infinite precision and then correctly rounded back to Python's float precision. ---------- nosy: +tim.peters _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43088> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
