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

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