title: sizeof float (3.0) vs (3.0f)
body: <p>What is the difference between sizeof(3.0) and sizeof(3.0f)</p>
  
  <p>I was expecting both of them to give the same result (sizeof float)..but its different.</p>
  
  <p>In 32 bit machine,gcc compiler,
  sizeof(3.0f) =>4
  sizeof(3.0)  => 8</p>
  
  <p>Why so?</p>
