New submission from Fredrik Johansson <[EMAIL PROTECTED]>: Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from math import ldexp >>> from sys import maxint
>>> ldexp(1.234, maxint//2) Traceback (most recent call last): File "<stdin>", line 1, in <module> OverflowError: math range error >>> ldexp(1.234, maxint) 0.0 >>> ldexp(1.234, -maxint) 0.0 >>> ldexp(1.234, -maxint-2) Traceback (most recent call last): File "<stdin>", line 1, in <module> OverflowError: long int too large to convert to int The first and third cases seem right. The second is clearly a bug. In the fourth case, it would be more correct to return 0.0 than to raise an exception IMHO. ---------- components: Library (Lib) messages: 64527 nosy: fredrikj severity: normal status: open title: ldexp(x,n) misbehaves when abs(n) is large type: behavior versions: Python 2.5 __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2487> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
