Gets the fraction as a double.

Usage

From source file:MainClass.java

public static void main(String[] args) {
    Fraction numer1 = Fraction.getFraction(3, 4);
    Fraction numer2 = Fraction.getFraction(51, 3509);

    Fraction numerator = numer1.multiplyBy(numer2);
    Fraction denominator = Fraction.getFraction(41, 59);

    Fraction result = numerator.divideBy(denominator);

    System.out.println("Expression as Fraction: " + result.reduce().toString());
    System.out.println("Expression as double: " + result.doubleValue());

    Fraction test1 = Fraction.getFraction(1, 2);
    Fraction test2 = Fraction.getFraction(2, 4);

    System.out.println("1/2 equals 2/4: " + test1.equals(test2));

    double value = Fraction.getFraction(10000, 100000).pow(6).doubleValue();
    double reduced = Fraction.getFraction(10000, 100000).reduce().pow(6).doubleValue();

    System.out.println("Fraction to pow 6 without reduction: " + value);
    System.out.println("Fraction to pow 6 with reduction: " + reduced);
}
