Convert azimuth into cardinal point
====================================

.. p23ready

The cardinal points or cardinal directions are
North, East, South, and West.

.. currentmodule:: PyAstronomy.pyasl
.. autofunction:: getCardinalPoint

Example
--------

::

    from __future__ import print_function, division
    from PyAstronomy import pyasl
    import numpy as np
    
    # Get the cardinal point for 10 azimuth angles
    azimuths = np.random.random(10) * 360.
    for azimuth in azimuths:
      cp = pyasl.getCardinalPoint(azimuth)
      print("Azimuth: {0:6.2f} deg, Cardinal point: {1:1s}".format(azimuth, cp))
