Subject: a formula file
Lines: 67
 
Now that my exams are over, I really dug deep into fractint.
And this is one of the results.
I haven't had the time to think of original names, or to search for
interesting par-files to accompany these formulas, maybe you can help
a bit.
Warning : I made this file for fractint on a 486 DX2, with FPU.
          I have no idea of calculation times on other platforms.
 
P.s. Ever tried to use statistical distributions in these formulas ?
     (I'm still working on that one)

Remark : use float=n for most configurations.
         don't forget to give a non-zero value to p2
