Like returning lists/matrices ?

yes... something that says: "module=2" "angle=2*pi" in different lines...

These are crafted string of yours, in which you can actually write your function's name, but it's a piece of work you have to do by yourself, not what I was talking about earlier (the CAS engine figuring out by itself how to use your user-defined functions

)

Anyway, good luck ^^
Try Disp it will make new lines.
And in a matrix form, you can put mat[0]:=xxx, mat[1]:=yyy or something.

after some tries i reached a program that is more or less what I wanted. On the CAS oS works fine. On the non-CAS it doesn't work at all. The only problem when I use the CAS oS is that if i have the Cis() defined before the program will return the entered number

Code: Select all: Define LibPub trigo(x)= Prgm Disp "módulo="abs(x) Disp "ângulo="angle(x) Disp abs(x)*cis(angle(x)) EndPrgm

But what is the definition of cis ?
If it is a "symbol" then yes, it is a primitive for the CAS. On non CAS, cis is a symbol and has to be defined in order to reduce to numbers.

cis(x)=cos(x)+i*sin(x)

Is that "i" the complex "i" or the letter "i" ?
Because on non CAS it makes a lot of differences.

the number complex "i" of course...

Why don't you use the function already available on calc : >Polar (with plain triangle) ?

humm, as i can see that expressionis the one used on your country... but on portugal we use p*cis(x)... what is the same thing but i want that on our default form...
