just something I bumped into and wasn't aware of

>>> aa
array([ 1.,  1.,  1.,  1.,  1.])
>>> aa.astype(int)
array([0, 1, 0, 0, 0])
>>> aa - 1
array([ -2.22044605e-16,   2.22044605e-16,  -2.22044605e-16,
        -3.33066907e-16,  -3.33066907e-16])
>>> np.round(aa).astype(int)
array([1, 1, 1, 1, 1])
