title: Exponential of very small number in python
body: <p>I am trying to calculate the exponential of -1200 in python (it's an example, I don't need -1200 in particular but a collection of numbers that are around -1200).</p>
  
  <pre><code>&gt;&gt;&gt; math.exp(-1200)
  0.0
  </code></pre>
  
  <p>It is giving me an underflow; How may I go around this problem?</p>
  
  <p>Thanks for any help :)</p>
