Hallo Luka, I am a newbie as well, but still here is my view of the probl=
em.
I do not know what you are trying to do exactly, but
if you know the max. number you are going ot get,  then you know
how many zeros you are going to have to add in the back conversion to string.
if max is. 99999 then every other number would have to have that many zer
as to conatin 5 chars.
00009
00099
00999 etc.
So you can simply add as many zeros as you need in the back conversion.

Regards:
Ivan
