title: what does the .f in 1000.f mean? c++
body: <p>I am following a tutorial on how to make a game with SDL. At a certain point in the tutorial I need to calculate the game's FPS. The tutorial does the following:</p>
  
  <pre><code>caption &lt;&lt; "Average Frames Per Second: " &lt;&lt; frame / ( fps.get_ticks() / 1000.f );
  </code></pre>
  
  <p>Now, I know exactly what the code does, except for the part where it divides by 1000.f. I've been looking but just can't find what .f means.</p>
  
  <p>So my question is, what does .f mean? And why is it there?</p>
