simple calculation of division

Hello,

I am writing a simple C program using Visual studio 2008.

And when I divide 5 / 9. I always get an zero. However, the correct value should be 0.5555.

Can anyone explain this?

Many thanks

Code:

---

//Calculate the temperature in celsius
int CalculateCelsius(int fahrenheit)
{
        float valueA = 0;
        int valueB = 0;
        float celsius = 0;
       
        valueA = 5 / 9; //Always displays zero
        valueB = fahrenheit - 32;
        celsius = valueA * valueB;

        return (int) celsius;
}

Because 5/9 is 0 (remainder 5, but you didn't ask for that). Now, 5.0/9.0 is 0.555555, or as near as the computer can get to that number in 32 bits.

Why do you return an int from your function, when you are attempting to generate a float or double? Even if you fix your division, as tabstop indicated, your calling function will never see that float.
