Wednesday, 02 August 2006 Algebrus is a "must have" software for everybody who needs to do either scientific analysis or just doing school homework. It provides user with numerous mathematical and analysis functions as well as allows unlimited extension of its functionality by means of user-defined types, constants, operators, routines, and libraries. Its extensibility 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 2D and 3D graphic plots of functions and data, command line execution console, and a syntax-highlighted XPascal editor as a part of the integrated development environment (IDE).
