RE: 200LX, 17b, 19b - Solver Problem?
Problem eventually solved. But further testing is needed.

Starting with
Code:
L(#PP,1-T*#P/360+FP(G(N))*#P/#C)

as
Code:
P=1-T*#P/360+FP((720+210+T)/360)*#P/#C)
it was easily seen by the result of P, that only the last digit of the result
could have an influence onto the IP(#PP) further down the road.

By changing the expression to
Code:
+L(#PP:RND(1-T*#P/360+FP(G(N))*#P/#C:13)) ! 2 less than precision 15 on 200LX !
the results are now exactly as when calculated with the respective ROM routines.

(For 17b/19b it therefore should be precision 9 - 2 = 7.)

Also the plot of the equation for T is now w/o any steps.

That leads to the assumption, that any solver equation which allows for forward/backward solving in all variables should show stair-step free plots in the respective vars if mathematically sound.

Your comments are welcome.

Thanks again,
Peter
