title: What is the significance of 0.0f when initializing (in C)?
body: <p>I've seen code where people initialize float variables like this:</p>
  
  <pre><code>float num = 0.0f;
  </code></pre>
  
  <p>Is there a significant difference between this and just doing the following below?</p>
  
  <pre><code>float num = 0; 
  </code></pre>
  
  <p>Thanks.. :)</p>
