title: Is there any C++ style guide that talks about numeric literal suffixes?
body: <p>In all of the C++ style guides I have read, I never have seen any information about numerical literal suffixes (i.e. <code>3.14f</code>,  <code>0L</code>, etc.). </p>
  
  <p><strong>Questions</strong></p>
  
  <ol>
  <li><p>Is there any style guide out there that talks about there usage, or is there a general convention?</p></li>
  <li><p>I occasionally encounter the <code>f</code> suffix in graphics programming. Is there any trend on there usage in the type of programming domain?</p></li>
