Mark Dickinson added the comment: Is there anything in the Python documentation that implies that '%.1f' % 2.25 should be the string '2.3'? I know that the documentation for the builtin round function implies that round(2.25, 1) should be (the closest representable float to) 2.3, but that's a separate issue.
As far as I can tell, the float formatting of Python derives its behaviour fairly directly from that of the C library. And the C language specification seems to be pretty much silent on the exact rounding behaviour of the %e, %f and %g conversion specifiers, so it's not clear that either the Linux result or the Windows result is wrong. I'm actually more surprised by the Windows result: I'd expect %f to do round-to-nearest, with halfway results like this one rounded to the string with even last digit. Incidentally, on OS X 10.4.11/Intel, I get the same as on Linux: Python 2.5.1 (r251:54863, Dec 18 2007, 11:48:56) [GCC 4.0.1 (Apple Computer, Inc. build 5370)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> print '%.1f' % 2.25 2.2 ---------- nosy: +marketdickinson __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1694> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
