Numpy array element-wise division (1/x)

Question

My question is very simple, suppose that I have an array like

array = np.array([1, 2, 3, 4])

and I\'d like to get an array like

<         


        

Answer 1

Other possible ways to get the reciprocal of each element of an array of integers:

array = np.array([1, 2, 3, 4])

Using numpy's reciprocal:

inv = np.reciprocal(array.astype(np.float32))

Cast:

inv = 1/(array.astype(np.float32))
