My vote is for consistency in numpy.
But it is unclear what consistency is.

What is truly confusing for newbie Python users (and a source for error even after 5 years of Python programming) is that

>>> 2/3
0

In that respect, I would think

>>> numpy.sqrt(2)

should give 1, but it gives 1.4142135623730951

So numpy does typechecking anyway (it gets an integer and makes it a float).

If that is the consistent behavior, then by all means

>>> sqrt(-1)

should return 1j.

Wouldn't that be the consistent thing to do????
