  There was nearly the same question few days ago. Look at the archives of
this list:

  PostScript language use RPN (Reverse Polish Notation):
(1/x^12) - (1/x^6) --> 1 x 12 exp div 1 x 6 exp div sub

  Nevertheless, I guess that your functions will have a strange appearance,
as the values seems to vary very heavily.
