The file INFINT.ZIP contains the following files :

- INFINT.DOC    This File
- INFINT.PAS    BP 7 Source of the TInfInt Object.
- PELL2.PAS     Demo program, that solves Pell's equation
                abs(x*x - n*y*y)=1
- BERNZAHL.PAS  Demo Program, that calculates Bernoulli-numbers.

The Problem
-----------

Sometimes it is necessary to do arithmetic with integer numbers
that are much bigger than the numbers a ordinary "integer" or
"longint" variable can hold, and one has to keep even the last
decimal, so using reals is not a solution. The "TInfint" object
soves this problem by defining an integer with a size that is
only limited by the available heap space.  (under DPMI this can
be a lot). I wrote the first version of this "library" in 1987 in
a work to get my diploma in mathematics in Turbo Pascal 3.0.  Now
I revised it to use the advantages of BP 7.
