Arduino Calculator functions.

[mowcius]

add x and y;
divide ANS by 2;
etc etc

Or do you want to be able to parse
(x + y) / 2

At first, I just want to implement single calculations (x+y etc.) and then I would like to implement the other stuff later.

That CORDIC stuff looks cool. I will read through it and see what I can work out.

Thanks,
Mowcius
