title: Precision of scientific notation in R
body: <p>How accurate is scientific notation in R? I'm generating data that as values like this:</p>
  
  <pre><code>-5.59924596431885e-320
  </code></pre>
  
  <p>Is this an accurate value? I know R is usual only accurate to 15 decimal places when the number is written like this:</p>
  
  <pre><code>-2.1411372887
  </code></pre>
  
  <p>So is the scientific notation accurate at such small numbers?</p>
