Howdy! I need to use numbers beyond the range of unsigned int variables... The numbers I''m working with will all be positive but will be in the area of 5 to 10 times the max value of an unsigned int. How do I go about messing with values that high? Thanks, Gorf

do a google search for "big integers"--that''s the technical term.

How appropriate. You fight like a cow.

You could use Lisp. Lisp handles big numbers transparently and elegantly, by switching representation when the number would overflow.

You could also use java, which has a BigInteger class.

Finally, I believe there is a Gnu numerics library(or something similar to that) which has big integers for c(or maybe c++, never used it).

Just out of curiosity... why do you need such high value numbers?

Could you not use some sort of scaling so that your numbers fall into a more ''friendly'' and generic data type?

I did something similar to what your talking about in VB6. I had created my own data type made up of 5 doubles and then made a bunch of functions to make it so that I could use those 5 doubles as one number. I forget the exact range I achieved. It was for a final project.
