Finally, to round to the nearest integer using the rounding half to even strategy, use np.rint(): Python >>> np.rint(data) array([[-1., -2., -1., 1.], [ 1., 1., -0., 0.], [-0., -1., 0., -1.]]) You might have noticed that a lot of the rounding strategies...
You can use round() to round a number to the nearest integer:Python >>> round(2.3) 2 >>> round(2.7) 3 round() has some unexpected behavior when the number ends in .5:Python >>> round(2.5) 2 >>> round(3.5) 4 2.5 is rounded down to 2, and 3.5 is rounded up to 4. ...
