title: Exponentials in python: x**y vs math.pow(x, y)
body: <p>Which one is more efficient using <code>math.pow</code> or the <code>**</code> operator? When should I use one over the other?</p>
  <p>So far I know that <code>x**y</code> can return an <code>int</code> or a <code>float</code> if you use a decimal
  the function <code>pow</code> will return a float</p>
  <pre><code>import math
  
  print( math.pow(10, 2) )
  
  print( 10. ** 2 )
  </code></pre>
