New submission from Guido van Rossum: Since 1e-1000 == 0.0 (on an IEEE-754 platform anyway), I would expect -1e-1000 to be -0.0. But it does not appear that way:
>>> 1e-1000 0.0 >>> -0.0 -0.0 >>> -1e-1000 0.0 However (correctly): >>> (-1.0) * 1e-1000 -0.0 >>> -(1e-1000) -0.0 I suspect the optimization for -x where x is a float literal is incorrectly triggering here. ---------- messages: 59113 nosy: gvanrossum severity: normal status: open title: -1e-1000 converted incorrectly versions: Python 2.5, Python 2.6, Python 3.0 __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1725> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
