I'm doing a simple code which converts an entered amount of degrees Fahrenheit to Celsius. I'm running sample test data and there appears to be a converting problem.

My first test data was 32 and it came out correctly with a conversion of 0 degrees Celsius. When I tried one (1), it gave me an output of zero (0) as with others numbers I have entered. Can you help me identify the problem?Code://This program will convert a temperature of Fahrenheit to Celsius #include <iostream> using namespace std; //Function Prototypes int Celsius(int); int main() { int F, // # of degrees Fahrenheit C; // # of degrees Celsius cout <<"This program will convert a temperature of Fahrenheit to Celsius." << endl; cout <<"Please enter the amount of degrees (integer) Fahrenheit." << endl; cin >> F; C = Celsius(F); cout << F << " degrees Fahrenheit converted to Celsius is " << C << endl; system("pause"); return 0; } //************************************************ //Definition of function Celsius. * //This function converts Fahrenheit to Celsius. * //************************************************ int Celsius(int F) { return ((5 / 9) * (F - 32)); // Formula used to convert Fahrenheit to Celsius }

Edit:

I know some answers will come out with a decimal, but I'm only concerned with "whole" numbers.
