title: only 6 decimal places for double
body: <p>I think this is a dumb question.
  but i cannot figure it out. Please don't shoot me. :P
  I want to get double value like
  8.000000111333. but I can only get up to 6 decimal places.
  for instance</p>
  
  <blockquote>
    <p>double _result = 8.000000111333;<br>
    DLog(@"%f", _result);</p>
  </blockquote>
  
  <p>the console print is - 8.000000</p>
