[Numpy-discussion] Complex zerodivision/negative powers not handled correctly
Hi, I have observed a problem with complex zerodivision and negative powers. With a complex zero the result is either zero or NaN NaNj, the first one is clearly wrong and the other one I don't know what is most reasonable some kind of inf or a Nan. This problem has been reported in the tracker as #1271.

Re: [Numpy-discussion] numpy and python 2.6 on windows: please test
Hi, this is really good news, thanks for working on this. I'm looking forward to switching from 2.4 to 2.6 at work but we really need numpy and matplotlib. I have successfully built numpy on windows using mingw. Some basic tests at the interactive prompt suggests it works. /Jörgen David Cournapeau skrev: > Hi, > > I think I finally solve most serious issues for numpy on python 2.6 > on windows.

[Numpy-discussion] Compilation failure on python2.4 win32
Hi, I cannot compile numpy (rev 2042) for python2.4 on win32, it works on python2.5. It looks like the call to function get_build_architecture in distutils.misc_util.py is python2.5 specific. /Jörgen C:\python\external\numpy>python setup.py config --compiler=mingw32 build --compiler=mingw32 install Running from numpy source directory.
