Powertoy Calculator

Power Calculator is a graphical calculator application for Windows XP released as a PowerToy, which, unlike the built-in offering, does not evaluate every time an operator is entered. Rather, the entire expression must be entered for calculation. In the Numeric calculator mode, it presents a visual keypad, in all other modes the expression has to be typed in. A scrolling text area maintains a history of all calculations. The application also supports functions, of any arity, which can later be reused.

The advanced view also shows a graph of functions, along with a list of all the saved functions. A flyout window...
