title: Intrinsic function to convert integers to real(16)
body: <p>What is the best way to convert an integer to a quadruple precision number?</p>
  
  <p>For double precision I use</p>
  
  <pre><code>StrainStep = MaximumStrain/dble(StrainIterations)
  </code></pre>
  
  <p>but now <code>StrainStep</code> and <code>MaximumStrain</code> are <code>real(16)</code>.  What do I use instead of <code>dble</code>?</p>
