title: Bug with outputting long numbers in javascript
body: <p>Here is the code:</p>
  
  <pre><code>var q = 10000000000000011;
  console.log(q);
  </code></pre>
  
  <p>Output will be:</p>
  
  <pre><code>10000000000000012
  </code></pre>
  
  <p>If I try to output <code>10000000000000010</code> or <code>10000000000000012</code>, everything is fine.
  Conversion to string doesn't help either.
  How can I avoid this bug?</p>
