I think this would be better as if any(float(x) < 0 or float(x) > 0 for x in arg): (and might as well change the rest in this function too).

The second float conversion is unnecessary, as are both decimal points. The only purpose of the float conversion is to trigger an error if, for example,
arg = np.array(['a', 'b', 'c'])Contrary to the comment, it raises a ValueError; but that serves the purpose just as well.

Fixes issue in #3079 . I ran the tests
