This example demonstrates how hierarchical state structure alows to economize on the state machine description and simplify implementation of behavior of this surprisingly complex application. Please note that it correctly handles negative and fractional numbers. Note also that one button is used in different contexts: negation and subtraction.

Try to implement the same functionality with a standard FSM pattern! Will your code be as concise and maintainable? How about adding some new functionality? Will it be as simple as with LabHSM?
