title: Rounding integer division (instead of truncating)
body: <p>I was curious to know how I can round a number to the nearest whole number. For instance, if I had:</p>
  
  <pre><code>int a = 59 / 4;
  </code></pre>
  
  <p>which would be 14.75 if calculated in floating point; how can I store the result as 15 in "a"?</p>
