Hi, I was wondering if the numpy function 'isinf' should return True for complex infinity. I encountered the following behavior that could be considered a bug:

...

...

import numpy as N N.isinf(1j*N.inf) True

...

...

1j/(N.array(1)-1) (nannanj) N.isinf(1j/(N.array(1)-1)) False

...

...

1j/(N.array([1])-1) array([ nan +nanj]) N.isinf(1j/(N.array([1])-1)) array([False], dtype=bool)
