Fraction

This class represents a fraction as a numerator and denominator. It provides the double equivalent of the fraction's value as well as a string representation that uses the numerator and denominator. It demonstrates type casting and the integer division issue.

Problem Statement

Write the code for the Fraction class. The solution must meet the following requirements:

• Should get the string representation of the fraction, as "numerator/denominator"
• Should get the numeric value of the fraction (as a real number)
• Should get the reciprocal of the fraction

Use the following class diagram when creating your solution.

public class Fraction
{
    public int Numerator { get; private set; }

    public int Denominator { get; private set; }

    public Fraction(int numerator, int denominator)
    {
        Numerator = numerator;
        Denominator = denominator;
    }

    public Fraction Reciprocal
    {
        get { return new Fraction(Denominator, Numerator); }
    }

    public override string ToString()
    {
        string stringValue = "";
        stringValue += Numerator + "/" + Denominator;
        return stringValue;
    }

    public double ToDouble()
    {
        // The casting of numerator to a double helps
        // ensure that we don't lose any fractional
        // portion due to integer division.
        double value = (double)(Numerator) / Denominator;
        return value;
    }
}
