Question

So I have a method in a class called Rational that passes in two ints, and I want to return a float, however this method is returning 0, and I have no idea why!

public static float DisplayFloat(int numer, int denom)
        {
            float result = numer / denom;
            return result;

        }

it is getting called like this in my main:

Console.WriteLine(Rational.DisplayFloat(12, 36));

Any ideas? I have no errors showing up in Visual Studio so I’m dumbfounded.

Answer 1

numer and denom are both ints, so when you divide one by the other the result is an int ; the result is then converted to a float, but it’s too late because you already lost the fractional part. If you want a float result, cast one of the operands before doing the division:

float result = (float)numer / denom;
