round() does not consistently preserve subtype of the ndarray,
is this known behaviour or should I file a bug for it?

>>> import numpy as np
>>> np.version.version
'1.7.0'
>>> a=np.matrix(range(10))
>>> a.round(decimals=10)
matrix([[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]])
>>> a.round(decimals=-10)
array([[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]])
