Confirmed. Considering that e and pi can be used as function's argument, IMHO should be considered a bug.

Several months ago I reported that if 'i' imaginary
belongs to a function definition, 'i' can NOT be used
as index in program. Worst, the program runs but zombie.
Conflict/bug is cnfirmed. Toke me days to elucidate.

I think that the BTS was thinked for this purpose, one may add a link to the discussion thread if is something discussed in the forum Good

Reading the link provided by Radovan seems there are strong reasons code side, still is something that may cause confusion because in the canvas i can be overriden... Umnik

I think that it is not good at all if a lot of observations are lost over the time.
Many of this was obtained with much work.
For this simple history with "i" I spent a lot of time, making firstly reproaches to myself.
It is clear that such a work is not to be assigned to Andrey. He gives us too much of himself.
After many years, the volume of the forum is big enough, being almost impossible to look inside for each problem.
Maybe we could think a way to solve, making periodically some synthesis or similar ?

Ioan



Hello Ioan,

I do not know how to do this right way, but during all these years I think this is inevitable. We are just forgetting things and rediscover them again, and there might be expected to be that way. Speaking for myself, it happens to me quite often (maybe because I am not getting any younger Wink ) . I agree that the volume of this Forum is quite large, lots of similar things are scattered all over the topics, and I really do not know how to put some order or synthesis of it, as you said.

Regards,
Radovan

Radovan !!!

You are number 1 +++ WebMaster. You can trust me from 10 years Mathsoft Collaboratory.
Their forum was not bad searching by: keyword, by date, by name. Since I joined, nothing
was left unattended or not doctored in one way or another. Real user needing help will
come back after re-thinking for a better targeted question.

Cheers, Jean

.... "i as an arguent in function" is simply not documented.
"i" is by defunition the imaginary. Naturally it can't be
used otherwise except within the core of a program as long
as there is no complex stuff in the work sheet.
Sierpinski from today "Uni" is all correct from educated
know how [Ah ! the learning curve ]. Albert Einstein
missed twice his entry to University. Why not some of us ?

When i is used inside functions, it disallows the function to correctly process complex numbers (without redefining i outside the function):

Quite right Mike, in numericals we have to learn few things
like learning alphabet. It made me shit bricks while working
the Laplace in closed control loops... i:=sqrt(-1)

Question related to using "i" as function's argument reviewed.
Now it is possible. New nightly build will be available soon.
