title: Expressing Radians C++
body: <p>How would I convert degrees to radians <strong>exactly</strong>. Rather than showing <code>0.785398</code> I want the program to show <code>pi/4</code>. </p>
  
  <p>I am currently using this script to convert degrees into radians. </p>
  
  <p><code>cout &lt;&lt; angle * M_PI / 180.0 &lt;&lt; " radians";</code></p>
