We already do that, NPY_INFINITY and -NPY_INFINITY.

Testing with arithmetic can raise overflows and underflows.
I think the correct isinf is to compare to NPY_INFINITY and -NPY_INFINITY.
Patch is attached to #1500

As far as I know, isinf has always created NaNs -- since 2006 it has been
defined on "unsupported" platforms as
(!isnan((x)) && isnan((x)-(x)))

I am seeing a problem on Solaris since I upgraded to svn HEAD.
np.isinf does not handle np.inf. See ipython session below. I am not
seeing this problem w/ HEAD on an ubuntu linux box I tested on
In [1]: import numpy as np
In [2]: np.__version__
Out[2]: '2.0.0.dev8480'
In [3]: x = np.inf
np.inf
