title: Formatting floats in a numpy array
body: <p>If I have a numpy array like this:</p>
  
  <pre><code>[2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01]
  </code></pre>
  
  <p>how can I move the decimal point and format the numbers so I end up with a numpy array like this:</p>
  
  <pre><code>[21.53, 8.13, 3.97, 10.08]
  </code></pre>
  
  <p><code>np.around(a, decimals=2)</code> only gives me <code>[2.15300000e+01, 8.13000000e+00, 3.97000000e+00, 1.00800000e+01]</code> Which I don't want and I haven't found another way to do it. </p>
