That's not a problem for dtoa.c, at least: dtoa.c avoids any use of subnormals in intermediate calculations. It's not really too much of a problem for Python in general, either. Windows typically operates in this mode. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18062> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
