abs(sexp_2(2*Pi*I)-L)=0.00326

abs(sexp_2(20*I)-L)=1.101E-9
abs(sexp_2(30*I)-L)=2.105E-14
I hope this helps.
Hi Sheldon -

yes, this helps, thank you. My speculation was unfounded.

P.s. I have still to use Pari/GP in the 2.2.11 version because in the next version they removed the feature, switched on be option -emacs, to give a textual "prompt" after each output (*) when Pari/GP was used in as subprocess in a GUI. I could use that "prompt" to detect end-of-answer and construct the conversation with the GUI around this. I don't know why they did this and after a query at Karim Belabas, I'm left with little hope that this behaviour would have attention on it. So as long as I use my nice GUI I've accordingly little hope to be able to upgrade some time...

(*) upps, it was modified in the next version and switched off in the >2.3 versions. First I thought it is a modification by the "readline.dll" people, but it seems to be in the sources of Pari/GP itself. Only if you use Pari/GP in a DOS-box/as a Windows-"console"-program, that "prompt" is still produced. I do not really understand what is going on here...
