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. Its development started in early 1999.
