XFOIL: number of digits in output
 
Hi, is it possible to increase the number of digits in the polar output values of CL, CD, and CM? I think I did this once, but really can't remember how ...

Thanks for your help!

Increasing number of digits in x-foil does not make sense, since, even with standard number of digits, errors related with methods applied exceed truncation errors by orders of magnitude.

Thank you very much for your reply. I guess I should have mentioned that I'm asking this because I would to see if I can increase the smoothness of sensitivities, calculated from finite differences.
