title: Literal long value
body: <p>Why do we have the L at that end here, I understand it's a literal value, but if the data type is long anyway, then is it needed?</p>
  
  <pre><code>public const long l = 100000000L;
  </code></pre>
  
  <p>Would this produce anything different?</p>
  
  <pre><code>public const long l = 100000000;
  </code></pre>
