Wanted: arbitrary precision integer arithmetic

[Edward R Scheinerman]

I am looking for subroutines that do basic arithmetic
(plus, minus, times, divide, modulus, input and output) with
very high (or even arbitrary) precision integers (up to about
200 digits). My preference is for C code (that will run under
UNIX System V), but FORTRAN is an acceptible alternative.

If you have such public domain source code, please send it
to me by e-mail at:

Thank you!
