title: Windows: just do a division and get result
body: <p>please I have</p>
  
  <pre><code>%V_Frame_Rate_cat% = 30000
  %V_Frame_Rate_Denom% = 1001
  </code></pre>
  
  <p>simply I would like createa a new variable %division% that contains the result of 30000/10001 = 29,97002997002997</p>
  
  <p>so <code>%division% = 29,97002997002997</code></p>
  
  <p>and another, called <code>%division2%  = 29.97002997002997</code> (difference is "." in place of ",")</p>
  
  <p>and another, called <code>%division3% = 29.97</code></p>
  
  <p>How can I do? thanks</p>
