Tim Peters added the comment: If it were treating doubles as floats, you'd get a lot more failures than this.
Many of these look like clear cases of treating _denormal_ doubles as 0.0, though. I have no experience with ICC, but a quick Google search suggests ICC flushes denormals to 0.0 by default, and the compiler flag "no-ftz" (no flush-to-zero) is needed to stop that; e.g., see https://software.intel.com/sites/default/files/article/326703/fp-control-2012-08.pdf ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24999> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
