How to printing numpy array with 3 decimal places? [duplicate]

Answer 1

An easier solution is to use numpy around.

>>> randomArray = np.random.rand(2,2)
>>> print(randomArray)
array([[ 0.07562557,  0.01266064],
   [ 0.02759759,  0.05495717]])
>>> print(np.around(randomArray,3))
[[ 0.076  0.013]
 [ 0.028  0.055]]
