New submission from TD22057 <[EMAIL PROTECTED]>: FYI Actual version is 2.5.2 running on Linux RHE4.
>>> import struct >>> fmt ='>f' >>> v=1.8183e-7 >>> v 1.8183000000000001e-07 >>> s=struct.pack(fmt,v) >>> struct.unpack(fmt,s) (1.818300034983622e-07,) Looks to me like the float->double conversion is not being zeroed out before the 4 bytes are written to it. FYI this is a fairly serious issue since it leads to incorrect results be read from files (at least for me anyway). ---------- components: Extension Modules messages: 74690 nosy: TD22057 severity: normal status: open title: struct returns incorrect 4 byte float type: behavior versions: Python 2.5.3 _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4114> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
