title: Preventing R From Rounding
body: <p>How do I prevent R from rounding? </p>
  
  <p>For example, </p>
  
  <pre><code>&gt; a&lt;-893893084082902
  &gt; a
  [1] 8.93893e+14
  </code></pre>
  
  <p>I am losing a lot of information there. I have tried signif() and it doesn't seem to do what I want. </p>
  
  <p>Thanks in advance!</p>
  
  <p>(This came up as a result of a student of mine trying to determine how long it would take to count to a quadrillion at a number per second)</p>
