Does this work with places=2 or 3 for the te value? That would be better. The precision is shocking, I have to say. I would suggest that in the comments, that something about this being the WinPython distribution would also be useful for these precision records. I would not think that it is the Microsoft C compiler that is a problem, but rather the numpy packages bundled with this Python derivative. The Microsoft compiler has never been an issue before, so I would suggest that the WinPython people have a precision bug in their code. Or maybe they have deliberately turned down their precision so that it appears as if their distribution is much faster than standard Python+numpy? Is it also WinPython that has problems with icons in the menus?
