New submission from Gregory Golberg <gri...@alum.mit.edu>: On some Python builds (2.5.2 and 2.6.1) the following program:
import sys from decimal import Decimal def show(n): print type(n) d = Decimal(str(n)) i = int(d) t = type(i) print t i2 = int(i) t2 = type(i2) print t2 n = - sys.maxint - 1 show(n) prints <type 'int'> <type 'long'> <type 'int'> While on 2.4 and 2.5.1 it prints: <type 'int'> <type 'int'> <type 'int'> This seems to happen only with -sys.maxint-1 number! This has been tested with the following builds: *** "Strange" result (with long): *** 2.6.1 (r261:67515, Feb 26 2009, 12:21:28) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] 2.5.2 (r252:60911, Jul 31 2008, 17:28:52) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] 2.5.2 and 2.6.1 on Windows Server 2003 *** "Expected" result (all int): *** 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] 2.5.1 (r251:54863, Oct 15 2007, 13:50:22) [GCC 3.4.6 20060404 (Red Hat 3.4.6-3)] 2.5.1 (r251:54863, Jul 31 2008, 23:17:40) [GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] 2.4.5 (#2, Aug 1 2008, 02:20:59) [GCC 4.3.1] 2.4.5 (#1, Jul 22 2008, 08:30:02) [GCC 3.4.3 (csl-sol210-3_4-20050802)] 2.4.3 (#1, Sep 21 2007, 20:05:43) [GCC 3.4.6 20060404 (Red Hat 3.4.6-8)] ---------- assignee: theller components: Interpreter Core, ctypes files: negmaxintbug.py messages: 82773 nosy: debedb, theller severity: normal status: open title: Strange behavior when performing int on a Decimal made from -sys.maxint-1 type: behavior versions: Python 2.5, Python 2.6 Added file: http://bugs.python.org/file13191/negmaxintbug.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5377> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
