Hey all (again, sorry for all the questions ^^;; )

I'm just wondering if there's a data type or if one can be made for storing very long numbers, but being able to perform mathmatical calculations on them? (i.e. not a string).

I want to use the Rnd function to generate a 20-digit number, e.g. 40229603967719402863. I can't store it int/long/etc as it's too long, I can store it in Double but then it makes it a floating point number.

Soo.. Any way to generate a number of this size and have it display the full value? I'm trying to generate a unique ID, you see
