Yacas is a general-purpose computer algebra system
. The name is an acronym for Yet Another
Computer Algebra System.

YACAS is a program for symbolic manipulation of mathematical expressions. It uses its own programming language
designed for symbolic as well as arbitrary-precision
numerical computations. The system has a library of scripts that implement many of the symbolic algebra operations; new algorithms can be easily added to the library. YACAS comes with extensive documentation covering the scripting language, the functionality that is already implemented in the system, and the algorithms used.
Yacas handles input and output in plain ASCII
or in OpenMath
, either interactively or in batch mode.
Computer algebra system
A computer algebra system is a software program that facilitates symbolic mathematics. The core functionality of a CAS is manipulation of mathematical expressions in symbolic form.-Symbolic manipulations:...

Programming language
A programming language is an artificial language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely....

Arbitrary-precision arithmetic
In computer science, arbitrary-precision arithmetic indicates that calculations are performed on numbers whose digits of precision are limited only by the available memory of the host system. This contrasts with the faster fixed-precision arithmetic found in most ALU hardware, which typically...
