title: Is floating point math broken?
body: <p>Consider the following code:
  </p>
  
  <pre><code>0.1 + 0.2 == 0.3  -&gt;  false
  </code></pre>
  
  <pre class="lang-js prettyprint-override"><code>0.1 + 0.2         -&gt;  0.30000000000000004
  </code></pre>
  
  <p>Why do these inaccuracies happen?</p>
