[Numpy-discussion] nan adds lots of whitespace

[Keith Goodman]

NaN adds a lot of whitespace in the representation of a matrix.

Without NaN:

matrix([[1, 2],
        [3, 4]])

With NaN:

matrix([[                  nan,            2.        ],
        [           3.        ,            4.        ]])

There's enough room for the wikipedia entry for nan.
