Here's a simple calculator implemented using FSM logic. Although the system (implmeneted in Calc.js) may look complicated, the logic with using it is very simple. Initialize a new instance of the calculator with:

let calc = new Calc();

Use is as follow:

Give one input to the calculator with

calc.receiveInput(input);

An input can be:

• a number, one of [0,1,2,3,4,5,6,7,8,9,'.'] (the dot is considered a number)
• an operation, one of Calc.OP.PLUS, Calc.OP.MINUS, Calc.OP.MULT, Calc.OP.DIV
• an equal operation using Calc.OP_EQ
• a reset operation (i.e. clear or clear all) using Calc.OP_RES

To get the current display on the calculator, use:

calc.getDisplayedNumber();

That's it!
