If you want to support values bigger than that, I seem to remember seeing a Big Integer class for Arduino. You can support up to 64-bit values using the long long int type. I suggesting storing your values using fixed point integers. The built-in float/double classes only use 32-bits and I think you would need more resolution than that for a calculator to be useful.
You will need to guard against invalid entries such as multiple decimal points, and also constrain the range of values that can be entered (for example by limiting the number of digits). For the latter, I'd use a finite state machine to deal with the decimal point, although perhaps somebody will think of a way to do it without that. You could achieve that by storing the digits and '.' characters as a string, or by updating a numeric value directly as each character is received. I think the basic idea would be that you have a variable holding the current total, and a variable holding the current operator, and a variable holding the value being entered.Įach time a new operator is entered, apply the previous operator to the total and the entered value, save that as the new total, clear the entered value and save the new operator.Įach time a digit is entered, add it to the value being entered. I have and when i find something it is to complex or they don’t how code or they use and lcd screen. I’m really new to this but think i can solve it if i atleast can get an exemple of how it would work with addition.Īnd to thoose i think goggle it.
code so i can press c to begin on a new rowĭid read something about using FunctionDeclaration but don’t get how to use it with keypad.lib.code so i can take the two diffrent numbers i have put in diffrent variables with the Keypad(eg.code for assigning variables so that i can have use bigger numbers then 9( eg.342 = num1) like store them or something.
The thing is that i i do not know how i shall shall continue. Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS ) I need some help on how i shall beging the code for an easy calculator that can do +, -, *, /.īyte rowPins = //connect to the column pinouts of the keypad
