title: Convert Single Element of Numpy Array into Another Type
body: <p>I have a Numpy array with data type float64. For example:
      <code>[1.35623 , 2.35124 , 5.12276, 0.12466]</code>. How can I change the data type of a single element of this array. I have tried using <code>astype()</code>, but it seems to return a scalar number rather a numpy array. How can I do this in Python 3.x? </p>
