title: man pages for c variable types
body: <p>Are there any Unix <code>man</code> pages or similar standardized reference for variable type declarations (in c)?</p>
  
  <p>For example, if I want details on the <code>float</code> variable type and different ways to declare it, is there a standardized reference in Unix?  The compiler man pages? Or is an online reference or book on C required?</p>
  
  <p>I just saw <code>float power=2.345f</code> when reading <a href="http://c.learncodethehardway.org/" rel="nofollow">Learn C the Hard Way</a>, was wondering what the <code>f</code> means, and quickly learned that <code>man 3 float</code> and <code>man float</code> do not produce anything, and even <code>man -k float</code>  does not seem to show any relevant results.</p>
  
  <p>So, where to look for definitive answers about c variable types and their declarations, preferably retrievable on the OS without internet access?</p>
