RE: [HP41] Lambert function RPN; question
Finally.

Full RPN program for infinite tetration calculation of the parameter value of type "X^(1/X)"; using "LW" 1:1 from the above links; R00 necessary because "LW" screw up the stack (I know, thats not a big program.. but math-prototyping on an HP41 is always fun):

Code:
 01 LBL "TETR"
 02 ENTER^
 03 1/X
 04 Y^X
 05 LN
 06 CHS
 07 STO 00
 08 XEQ "LW"   ; function from this forum and documented on github
 09 RCL 00
 10 /
 11 RTN
 12 END

HP71B 4TH/ASM/Multimod, HP41CV/X/Y & Nov64d, PILBOX, HP-IL 821.62A & 64A & 66A, Deb11 64b-PC & PI2 3 4 w/ ILPER, VIDEO80, V41 & EMU71, DM41X
