## Class ContinuedFraction

• `public abstract class ContinuedFractionextends IterativeMethod`

This class provides the means to evaluate continued fractions (1). To create a continued fraction, authors subclass this class and provided concrete a and b coefficient methods.

For example, this is the continued fraction for the exponential function defined by (2):

` ContinuedFraction exponential = new ContinuedFraction() {     public double getA(int n, double x) {         if (n == 0) {             return 1.0;         } else if (n % 2 == 0) { // even             return 2.0;         } else { // odd             return n;         }     }         public double getB(int n, double x) {         if (n % 2 == 0) { // even             return x;         } else { // odd             return -x;         } } `
