title: R not working properly with big numbers because of default options?
body: <p>Seems like R coerces big numbers and cannot compare them effectively:</p>
  
  <pre><code>x = 123412415124231251233213
  x == 123412415124231251233214
  [1] TRUE
  x == 123412415124231251233217
  [1] TRUE
  </code></pre>
  
  <p>Any idea why (maybe a C limitation) and how can that be fixed ?</p>
  
  <p>And look what happens if I convert to character:</p>
  
  <pre><code>x &lt;- as.character(123412415124231251233213)
  x
  [1] "123412415124231247898884"
  </code></pre>
