DOC: Add narrative documentation about printing and formatting arrays #29476
Description
Overview
As discussed in #29450, I propose adding narrative documentation that explains how to print and format NumPy arrays. Adding it to Numpy howtos section seems appropriate.
Background
There have been several questions and issues related to printing arrays, as shown below. I believe a narrative guide would be helpful for users to understand current behaviors.
- DOC: document that
set_printoptionsdoesn't apply to numpy scalars #29409 - np.set_printoptions doesn't affect floats #11048
- BUG: Fix unicode(unicode_array_0d) on python 2.7 #9201
