Working with very large numbers.

Working with very large numbers.

[McDoobie]

Alright...I know about long_integers and long_long_integers and all that.

What I'm trying to figure out is how do I work with numbers in which the 
standard supplied types are just too small? Specifically, how do I allocate 
storage dynamically based upon the size of the integer entered?

I was thinking about using something along the lines of ...

type big_ass_num;
type biggie_ptr is access big_ass_num;

type big_ass_num is (s , (len)'value);

Big_Kahuna: biggie_ptr'(big_ass_num'Range(<>));
Little_Kahuna: biggie_ptr'(big_ass_num'Range( Big_Kahuna > ... (<>));

Or some crazy crap along those lines.

Anyways, as you can tell, I havent quite got the gist of it yet.

Any help would be appreciated.

Sounds like you want extended precision numbers. Look on the adapower
web site for a package enabling just such types.

I found the Unlimited Numbers package, but the link seems to be broken.

I'll keep poking around to see if I can come up with something.
