How to make NumPy print trailing 0s?

Question

When printing arrays, Numpy replaces trailing 0s with s, e.g.

[-0.678231 -0.618304 -0.6077    0.014845]

How can I fix this and make it print the 0s?

Also, I wonder why the developers thought this was a good default. — MWB, Jul 20 '16 at 23:31

You can use numpy's set_printoptions with a custom formatter to set the precision and exact format of the output; for your case,

np.set_printoptions(formatter={'float': '{: 0.3f}'.format})

should do the trick.

Sadly, the printed number will not be lined up in the decimal separator – Muhammad Yasirroni Jan 17 '23 at 03:38
