The Advanced Sci/Eng Calculator offers 18 digit precision expression evaluation, over 100 functions, variable input, graphing capabilities, unit conversion, interpolation, polynomial regression, linear algebra, and optimization. It can solve systems of linear, nonlinear, and differential equations.

At its core, this software functions as a calculator and is capable of evaluating expressions with over 100 functions like trigonometric and inverse functions, logarithmic and exponential functions, statistical distributions, Euler functions, conditional statements, and user-defined functions. Expressions are entered using customary algebraic notation, allowing for easy modification or correction, and can be recomputed at will. In addition to traditional functions, the software also offers unit conversions, physical constants, computer math, and function graphs.
For advanced users, the software provides access to less trivial operations, including numerical integration and differentiation, interpolation using linear or cubic spline methods, statistics such as calculating mean and standard deviation, histograms, polynomial regression, and column operations on stat data. Additionally, users can solve polynomial roots, perform linear algebra with vector and matrix operations, and solve systems of linear equations.
Among its many advanced features, Kalkulator also includes hard-to-find capabilities like evaluating systems of non-linear and differential equations, multi-argument function extremum searches, and point or histogram fitting with arbitrary functions. Despite its extensive capabilities, Kalkulator is designed to allow the user to access only the features they need without being obstructed by those they don't. The software also includes disk save/restore, Help files, and other added features.
Finally, it's worth noting that Kalkulator has been evolving on various platforms for over 15 years, providing advanced and reliable performance for users. With an experienced author boasting over 25 years of active experience in numerical methods and software development, Kalkulator represents the pinnacle of what a scientific and engineering calculator should be.
