CCCalc 1.9

Free calculator for Windows with an editable "tape" instead of one-line screen, which makes everyday calculations very convenient. Performs plus, minus, multiply, divide, square root, and percent calculations. Implies no limitations on precision and provides controllable rounding-up. Remembers everything forever and allows one to browse through full calculation history as if it were a text and reuse numbers or correct any misprints at any moment.
