Summary: Free packages via FTP
X-Newsreader: TIN [version 1.2 PL1]
This is the file BIGNUMS.TXT from ripem.msu.edu, last updated January 1994.
In response to Email requests, I have assembled this list of
large-integer arithmetic packages of which I have heard.
Most of these are C function libraries, available in source form.
A few also deal with floating point numbers.
For your convenience, I have placed copies of
some of these on ripem.msu.edu (35.8.1.178). They are
available for anonymous FTP in the directory "pub/bignum".
However, what I have may not be the most current version in all cases.
Here they are, in no particular order:
mp
Multiple Precision package that comes with some Unixes
Multiple precision package accessed via -lmp flag on your
compiler. Provides +, -, *, /, gcd, exponentiation,
sqrt. Comes with SunOS, NeXT Mach, BBN Mach 1000,
and probably a few others. See "man 3 mp".
Object code only, of course.
PARI
Henri Cohen, et al., Universite Bordeaux I, Paris, FRANCE
Multiple precision desk calculator and library routines.
Contains optimized assembly code for Motorola 68020,
semi-optimized code for SPARC, and apparently rather slow
generic C version. Does both integers and reals.
Does vectors and matrices as well as scalars.
Contains a number of advanced functions, some of which I've
never heard of. ("Weber's function"?)
Has a factorization function, primality test, & other related stuff.
Plenty of TEX documentation.
Public domain, but you can't distribute modified versions.
Available via anonymous FTP from ftp.inria.fr:lang/ and
math.ucla.edu. The ucla site has Mac, MSDOS, OS/2, and
NeXT-specific versions there in addition to:
Filename: pari-1.37.tar.Z (There are now more recent versions)
Arithmetic in Global Fields (Arith)
Kevin R. Coombes, David R. Grant
Package of routines for arbitrary precision integers or
polynomials over finite fields. Includes basic +, -, *, /
and a few others like gcd. Source code in C.
Distributed under the terms of the GNU public license.
Includes man pages and TEX documentation.
Filename: arith.tar.Z
Arbitrary Precision Math Library
Lloyd Zusman Los Gatos, CA
C package which supports basic +, -, *, /. Provides for radix
points (i.e., non-integers). Not as polished as the others here.
Posted to comp.sources.misc in October 1988.
Filename: apml.tar.Z
BigNum
J. Vuillemin, INRIA, FRANCE, and others.
Distributed by Digital Equipment Paris Research Lab (DECPRL)
A "portable and efficient arbitrary-precision integer" package.
C code, with generic C "kernel", plus assembly "kernels" for
MC680x0, Intel i960, MIPS, NS32032, Pyramid, and of course VAX.
This is probably one of the better-known packages of this type.
Implements +, -, *, /, mod, plus logical operations OR, AND, XOR.
Both signed and unsigned arithmetic available.
Available via email from librarian@decprl.dec.com.
You will receive 5 shell archives. Give your postal address
and you will also receive printed documentation from France.
Package includes TEX documentation.
Publicly available for non-commercial use.
I removed this from my archive when I heard a rumor that PRL
doesn't like others to distribute it. However, BIGNUM *is*
distributed as part of ecpp (see below).
Lenstra's LIP package
Arjen Lenstra Bellcore
Portable unsigned integer package written entirely in C.
Includes +, -, *, /, exponentiation, mod, primality testing,
sqrt, random number generator, and a few others.
An earlier version of this package is the only of these packages
I have actually used. It works well and is very portable.
I haven't done any benchmarks against the others, but the code
looks clever & Lenstra is an accomplished number theorist.
LIP replaces lenstra-3.1.c. The package now includes encrypted
source code; to obtain the decryption key, you must send a
signed license agreement to Bellcore. See the documentation.
Filename: lenstra-LIP-package.tar This is a collection of
all the files in flash.bellcore.com:/pub/lenstra
bmp (Brent's Multiple Precision?)
R. P. Brent
1981 vintage FORTRAN code to do extended precision floating &
fixed point arithmetic. Includes most of the mathematical
functions you'd find in a FORTRAN run-time library.
This code is an ACM algorithm, number 524.
To obtain, send a mail message to netlib@ornl.gov
containing the line "send mp.f from bmp" or better yet, perhaps
just start with "help".
SPX
Kannan Alagappan & Joseph Tardo, DEC
This is a huge prototype public key authentication system
based on RSA. I mention it here because those who have heard
of SPX have probably correctly guessed that it contains a large
integer package and I want to inform you that the large integer
package it contains is indeed DEC's BigNum from France.
You can get a beta test copy of SPX from crl.dec.com (192.58.206.2).
Use it only for testing, as it "may" expire on a certain date.
(I don't know whether this has expired yet.)
amp (Antti's Multiple Precision?)
Antti Louko alo@kampi.hut.fi
Multiple precision integer package in C. Includes +, -, *, /, %,
pow, mod, 1/x mod y, random, sqrt, gcd. Available for non-commercial
use. The package includes "share-secret", a public key system based
on the Diffie-Hellman algorithm.
This is normally part of the well-known "des-dist.tar.Z",
but I have removed the DES part to avoid having to deal with
cryptographic export laws, and have named the result:
Filename: amp.tar.Z
gennum
Per Bothner U of Wisconsin-Madison
C++ routines and classes to do generic arithmetic, both
integer and rational. Part of the "Q" programming system.
Distributed under the terms of the GNU public license.
Obtained from cygnus.com.
Filename: gennum.tar.Z
MIRACL

UBASIC
Prof. Yuji Kida, Rikkyo University, Nishi-Ikebukuro 3, Tokyo 171, Japan
kida@rkmath.rikkyo.ac.jp
Multiple-precision version of the BASIC programming language,
for MS-DOS. Includes floating point. Said (by Keith Briggs)
to be pretty fast. Object only, I think. ervin@morekypr.bitnet
says: "This is the best package that I know of for
fast arithmetic. Has a version optimized for 386 machines. Includes
routines to do MPQS, the fastest currently known general factoring
algorithm. An additional file is at both sites to allow MPQS to use
hard drives so that it can factor up to 80 digits. Many number
theoretical functions are included in UBASIC. It allows over 2500
digits of precision."
Available via anonymous FTP from shape.mps.ohio-state.edu,
or simtel20.army.mil, or wuarchive.wustl.edu.
calc_v22
Unknown
MS-DOS C-like language that allows "infinite" precision.

GNU bc
Author: Philip A. Nelson (phil@cs.wwu.edu)
GNU bc is an interactive algebraic language with arbitrary precision.
GNU bc is almost the same as bc & dc in some Unixes.
Filename: bc-1.02.tar.z (for example, in GNU prep.ai.mit.edu:pub/gnu/)
bc & dc
bc is an interactive processor for an arbitrary precision arithmetic
language or just compiler/preprocessor for dc calculator with arbitrary
precision; they comes with some Unixes.
Built-in support in other languages
Various
Multiple precision arithmetic is available in a number of
programming languages, such as Lisp and ABC (cf. mcsun.eu.net).
Version 8 of the programming language Icon (Griswold's successor
to SNOBOL4 available from cs.arizona.edu) has large integers.
Perl (by Larry Wall, available from devvax.jpl.nasa.gov)
includes source, in Perl, for such a package, but it's probably
not suitable for serious use.
For some of these, source code may be available. This list is
long enough, so I'm not going to pursue it aggressively.
Thanks to Keith Briggs and several others who contributed to this list.
