title: How can I instruct less to ignore math for certain styles?
body: <p>I'm using the new <code>calc</code> function in CSS to get the width for an object, as in:</p>
  
  <pre><code>width: calc(100% - 40px);
  </code></pre>
  
  <p>Unfortunately, since this is in a LESS file, LESS is "helpfully" pre-converting this to 60% during compile time.</p>
  
  <p>I want less to ignore math when it's in a <code>calc</code> function since I need the <em>browser</em> to do this calculation, not less.</p>
  
  <p>Is there anyway I can make LESS ignore this calculation so I can pass it straight to the browser?</p>
