title: printing long double goes wrong
body: <p>I was working with Dev-Cpp with my TDM-GCC 4.9.2 64-bit Release. But suddenly got stuck in printing long double values. </p>
  
  <pre><code>     #include&lt;stdio.h&gt;
       void main(){
       long double a = 22.0/7.0;
       printf("%Lf",a);
  }
  </code></pre>
  
  <p>It compiled well. Then when I ran it it said : "Error 216: This version of %1 is not compatible with the version"</p>
  
  <p>What should I do?</p>
  
  <p>I am not such a good programmer. If you would put some explanations and help me fix this I would be grateful </p>
