DNCalc

DNCalc This program resembles the calculator that is (or was) in the Dos Navigator program. It was written under the influence of a good impression left by using this calculator, after which I had the desire to write something similar for Windows. It supports basic arithmetic operations, brackets, trigonometric functions, and logical operations. Has two independent variables, X and Y. Outputs results in multiple number systems at once. Can be placed on top of all windows. Remembers the history of calculated expressions.
