title: Trouble using mpir_ui type in my code
body: <p>I wanted to use this function </p>
  
  <pre><code>int mpz_cmp_ui (mpz t_op1, mpir_ui op2)
  </code></pre>
  
  <p>For that I have to supply mpir_ui </p>
  
  <p>so whenever I try to declare this , </p>
  
  <pre><code> mpir_ui myui; 
  </code></pre>
  
  <p>it says:  </p>
  
  <pre><code> Error: identifier mpir_ui is undefined 
  </code></pre>
  
  <p>Am I missing any header file?  </p>
  
  <p>All other types and functions work , but only this one is failing.  </p>
  
  <p><strong>These are my header file</strong></p>
  
  <pre><code>#include &lt; cstdio&gt;
  #include &lt; stdlib.h&gt;
  #include &lt; stdio.h&gt;
  #include &lt; gmpxx.h&gt;
  #include &lt; iostream&gt;
  #include &lt;mpirxx.h&gt;
  #include &lt;math.h&gt;
  #include &lt;windows.h&gt;
  #include &lt;mpir.h&gt;
  #include&lt;time.h&gt;
  #include&lt;string&gt;
  </code></pre>
