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
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.
