I would like to know if there are any public domain software packages
in either executable or source code which do either of the following
- perform arbitrary precision arithmetic.
- factorise large numbers.
- test for primality.
I know that the first of these was asked for before in sci.crypt, but I have
lost that particular list. I am particularly (but not exclusively) interested
in packages which run on IBM compatibles. If they are source code, please
say what language they are written in.

This library contains C sources and assembler sources for VAX/ULTRIX, VAX/VMS, MIPS, 68020, NS and Pyramid machine. Note the next version will contain a C++ interface. To obtain this package, and/or the PRL report #2 "Bignum: a portable and efficient package for arbitrary precision arithmetic", send your request to: librarian@decprl.dec.com or Digital-PRL Attn librarian 85 Av Victor Hugo 92500 Rueil-Malmaison, FRANCE The package is sent by electronic mail. --- Jean-Claude Herve.
