Thank you Rudy, I have been thinking of constructing the string myself too,
cheers for showing it to me.
In fact I wanted to know if it was possible to set a format, like in c
int num = 15;
printf("here is my 5 digits number : %5d !", num);

would output:
here is my 5 digits number : 00015 !

Well, at least that what I remember from my C courses even if I don't practise
the printf..

But your function is fine for outputting results as strings, thank you.

>         str = '0' + str;
>     return str;
> }
> // --></script>

Cordialement,
