Hi everyone, I've run into some unexpected behavior with Numpy on Sage 4.6 (running on Mac OS X 10.6.6). Specifically in the binary_repr function, I get empty strings. For instance:
$ sage ---------------------------------------------------------------------- | Sage Version 4.6, Release Date: 2010-10-30 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage [1]: import numpy as np sage [2]: np.version.version '1.3.0' sage [3]: np.binary_repr(17) '' sage [4]: np.binary_repr(42) '' sage [5]: np.binary_repr(3) '' Whereas in my other Python installation (EPD), things work fine: $ python Enthought Python Distribution -- www.enthought.com Version: 7.0-1 (32-bit) Python 2.7.1 |EPD 7.0-1 (32-bit)| (r271:86832, Dec 3 2010, 15:41:32) [GCC 4.0.1 (Apple Inc. build 5488)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import numpy as np >>> np.version.version '1.5.1' >>> np.binary_repr(17) '10001' >>> np.binary_repr(42) '101010' >>> np.binary_repr(3) '11' Is this an issue with the version of NumPy installed in Sage?
