## ARIBAS

**Version 1.64, January 2010**

ARIBAS is an interactive interpreter for big integer arithmetic
and multi-precision floating point arithmetic with a Pascal/Modula
like syntax. It has several builtin functions for algorithmic number
theory like gcd, Jacobi symbol, Rabin probabilistic prime test,
factorization algorithms (Pollard rho, elliptic curve, continued fraction,
quadratic sieve), etc.

ARIBAS is used for the examples of number theoretic algorithms in the book
Algorithmische Zahlentheorie
by O. Forster.

**Recently added features**
(see also file
CHANGES164.txt)

There are versions of ARIBAS for

- UNIX workstations
- LINUX (80386-family)
- MacOS X
- MS Windows 95/98/XP or higher
- MS-DOS
- ATARI-ST.

ARIBAS is a compact system, written in C, and easy to install.
The UNIX (and LINUX) version has a GNU-Emacs interface, the
versions for MS-DOS and ATARI have a builtin Mini-Editor,
and the version for Windows 95/98/XP/.. comes with the usual
Windows GUI (view screenshots)
For the versions running on Intel's 80X86 processors,
some critical routines were written in Assembler,
so ARIBAS runs especially fast under LINUX or
Windows 95/98/XP/.. on a Pentium Computer.
