Pressing this softkey empties the input line of the calculator.
After inputting a desired arithmetic statement in the input line of the calculator, pressing this key starts the
calculation. The result is displayed in the pocket calculator.
Selecting this softkey enters the result in the input field at the current cursor position and closes the
pocket calculator automatically.
Pressing this softkey aborts the calculation result (if any) and exits the pocket calculator.

To calculate auxiliary points on a contour, the pocket calculator offers the following functions:
● Calculating the tangential transition between a circle sector and a straight line
● Moving a point in the plane
● Converting polar coordinates to Cartesian coordinates
● Adding the second end point of a straight line/straight line contour section given from an angular relation
