The numpy approach sacrifices correctness for speed (you sometimes get unexpected results in some corner cases, see below), the cpython way sacrifices speed for correctness. >>> round(56294995342131.5, 2)
56294995342131.5
>>> round(56294995342131.5, 3)
56294995342131.5
>>> np.round(56294995342131.5, 2)
56294995342131.5
>>> np.round(56294995342131.5, 3)
56294995342131.51
