Algebrus is a sophisticated software for scientific and general purpose calculations. It provides user with numerous mathematical and analysis functions, and allows unlimited extension of its functionality by means of user-developed routines and libraries. Extendibility is based on a built-in simple to learn and yet powerful programming language XPascal. Algebrus can be used both as a simple "evaluate-while-typing" calculator and as a powerful mathematical analysis application, which includes graphic plots of functions and data, command line execution console, and a syntax-highlighted XPascal editor as a part of the integrated development environment. Algebrus has the following major features.
