Hello,

First of all some background. My friend and I are having a bit of a competition over theoretically infinite number storage. We have agreed that the first person with a working arbitrary precision integer library with the theoretical ability to store an infinitely large number (IE: if the hard drive was big enough it would fill it up with the number) shall win. My plan has been to use .int files with the following format:

1-bit : Sign (1=positive, 0=negative)

31-bits : data (0=END)

data-bits : base 256 little endian number info

max FNAME_MAX-bits : next File (to be multiplied by 256^31 and added to this number)

I have it working, but only as a recursive function and I realized that this violates the theoretical infinity idea by relying on having enough space on the stack for all my recursive calls, which will be bounded by RAM and/or the system. Unfortunately some of my recursive functions (like my multiply function) are rather complicated, with multiple points of recursion, in multiple directions. I have been trying to convert them to iterative formats, to no avail. I am wondering if there is a general way to convent a recursive function into an iterative one? If not does anybody have a more iterative solution to my infinite storage problem?
