Kalkulator liczb rzeczywistych

0

Witam. Czy jest tu ktoś kto ogarnia wxWidgets? Napisałem program, który wyświetla w oknie kalkulator z przyciskami natomiast wynik wyświetlany jest tylko jako liczby całkowite, bez przecinków. Czy ktoś wie, co muszę zmienić w kodzie?

Podaj przykład działania, które wykonujesz, a nie tylko sam wynik, który wynosi 0.
Jeśli wykonujesz np. 1.2 + 2.3, to wynik będzie całkowity, ponieważ przed wykonaniem działania wywołujesz wxAtoi() na tych wartościach.
Spróbuj wykonać 1 / 2.

1

wxAtoi odnosi się do wartości INT. Spróbuj wxAtof

3

W jego kodzie jest

int Operand1, Operand2, Operators;

Zmiennoprzecinkowych używa tylko przy wyniku końcowym.
Ergo najpierw powinien ogarnąć ten problem.

Kalkulator liczb rzeczywistych
