title: Is it better to write 0.0, 0.0f or .0f instead of simple 0 for supposed float or double values
body: <p>Hello well all is in the title. The question apply especially for all those values that can be like <code>NSTimeInterval</code>, <code>CGFloat</code> or any other variable that is a float or a double. Thanks.</p>
  
  <p>EDIT: I'm asking for value assignment not format in a string.</p>
  
  <p>EDIT 2: The question is really does assigning a plain <code>0</code> for a float or a double is worst than anything with <code>f</code> a the end.</p>
