title: Javascript multiplying a String value
body: <p>Why when I do this:</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>console.log('2551.01' * 100);</code></pre>
  </div>
  </div>
  </p>
  <p>It logs:</p>
  <pre><code>255101.00000000003
  </code></pre>
  <p>But when I do this:</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>console.log('2551.02' * 100);</code></pre>
  </div>
  </div>
  </p>
  <p>It works just fine, logging this:</p>
  <pre><code>255102
  </code></pre>
