Enter the acceptable error
Error %

   What percentage error are you willing to accept?
   eg 0, 0.1, 0.2, 0.5, 1 (0.5 is a good choice).

Enter zero if you only want perfect results that give exactly the result that you requested. However there may be no such results. In that case you might be willing to use a gear train that produces a close approximation with a small error. Choose what percentage error you are willing to accept.
