title: Swift Rounding up Double
body: <p>I am trying to round a double up to a whole number,</p>
  
  <pre><code>var numberOfBottles = totalVolume / volumeEachBottles
  </code></pre>
  
  <p>for example <code>numberOfBottles = 275.0 / 250.0</code>
  that would give me <code>1.1</code>, I need  it to round up to <code>2</code></p>
