J'aimerais enregistrer une variable (A par exemple) dans une chaine (Str1 par exemple). Mais je ne connais que la fonction expr( qui fait l'inverse :( . Je ne sais pas si c'est possible mais je me rappelle avoir fait ceci...

Si tu veux declarer une chaine fais comme ça:

Code: [Select]

"Salut, monde!" (STO->) str1

----------------------------OU----------------------

Input "", str2
Disp str2
Mais je ne comprehends pas ce que tu dis trés bien :S

Oh ok. ;D
Je crois que je ne me suis pas très bien exprimé...
Bon j'ai ceci comme code:

Code: [Select]

Input A
...
//Et là je voudrais faire une chose comme A->Str0 mais ERR:DATA TYPE...
Oh ok. ;D
I think I am not very well expressed...
So here is the program:

Code: [Select]

Input A
...
//Here, I would like to do something like A->Str0 but ERR:DATA TYPE...

I would like to change a number into a string.
I know the input fonction. The code:

Code: [Select]

Input "NUMERATEUR:",A
Input "DENOMINATEUR:",B
Output(5,1,"CALCUL
lcm(A,B->C
//Here, I want to change the variable A into Str0
//The same with B and CI am French so my English it a bit bad. ;D

oooh, transformer un numero pour une chaine:

Code: [Select]

:{0,1→L₁
:{0,N→L₂
:LinReg(ax+b) Y₁
:Equ►String(Y₁,Str1
:sub(Str1,1,length(Str1)-3→Str1

Are you sure? The calculator say ERR:DIM MISMATCH on "linReg(ax+b) Y1"... :(

This is indeed the way to convert a number into a string, and this code should work. Are you sure you entered it correctly?
