title: Overflow in Numpy Cosh Function
body: <p>I am getting overflow error at cosh function in this simplified code:</p>
  
  <pre><code>import numpy as np
  x = np.linspace(0,10,100)
  for i in range(np.size(x)):
      print np.cosh(20*x[i]**2)
  </code></pre>
  
  <p>Is there a way to workaround this easily?</p>
