Not only does DreamCalc give you an intuitive and almost tactile experience, it is a fully featured graphing calculator that can graph functions and plot list data in an instant (no more setting up spreadsheets). In fact, it is a match for many dedicated graphing packages, but far easier to use.
DreamCalc offers a full range of scientific functions, statistics, complex numbers, base-n logic, unit conversions, numerical calculus and built-in constants and a powerful polynomial solver.
Select from Reverse Polish Notation or pre-fix or post-fix algebraic input, and with the optional ability to run in your Windows system tray, DreamCalc will always be there whenever you reach for a calculator.
DreamCalc is free for non-commercial use. Premium features, such as graphing, require a paid upgrade. Ten percent of sales go to charity.
