title: Does const go before or after CGFloat?
body: <p>Does it even matter? <a href="https://stackoverflow.com/questions/5503352/const-before-or-const-after">Const before or const after?</a> I'm guessing that whether I put <code>const</code> before or after <code>CGFloat</code> it makes the value of <code>CGFloat</code> constant, but what about the pointer? Is this right for Objective-C:</p>
  
  <pre><code>// Example.h
  
  extern CGFloat const kPasscodeInputBoxWidth;
  
  
  // Example.m
  
  CGFloat const kPasscodeInputBoxWidth = 61.0f;
  </code></pre>
