title: Getting 2 digits floating number isn't working as expected
body: <p>I have this number : -0.0166667 and I would like to get only two floating digits, so the number should be -0.01</p>
  
  <p>I tried this</p>
  
  <pre><code>-0.0166667.toFixed(2)  # gives : -0.02
  </code></pre>
  
  <p>and also this </p>
  
  <pre><code>Math.round(-0.0166667 * 100) / 100 # also gives : -0.02
  </code></pre>
  
  <p>But both of them transform the number to -0.02 instead of -0.01</p>
  
  <p>What's wrong here ?</p>
