Hello,
the following operation seems strange to me
>>> np.left_shift(2,-1)
0
I would have expected a right_shift by one.
The documentation on
http://docs.scipy.org/doc/numpy/reference/generated/numpy.left_shift.html#numpy.left_shift
also says that the operation is equivalent to multiplying x1 by 2**x2.
That's not the case!
Markus
