public int getNumerator() 

Source Link

Document

Gets the numerator part of the fraction.

This method may return a value greater than the denominator, an improper fraction, such as the seven in 7/4.

Usage

From source file:FractionExampleV1.java

public static void main(String args[]) {
    Fraction twoThirds = Fraction.TWO_THIRDS;
    Fraction fraction_whole = Fraction.getFraction(2, 2, 3);
    Fraction fraction = Fraction.getFraction(27, 98);
    Fraction fraction_double = Fraction.getFraction(4.56);
    Fraction fraction_string = Fraction.getFraction("2 1/3");

    System.err.println(twoThirds.doubleValue());
    System.err.println(fraction_string.getNumerator());
    System.err.println(fraction_whole.divideBy(fraction_double));
    System.err.println(fraction.divideBy(fraction));
