title: Fortran format 1P10E11.3
body: <p>Does anyone know what this format line means in fortran:</p>
  
  <pre><code>FORMAT(1x,F7.0,2x,1P10E11.3)
  </code></pre>
  
  <p>I know the first part is one repetition of float number but I don't understand how many exponential data points are read in the second part and what that P is for.</p>
