Java Double isInfinite() Method with Examples

by Online Tutorials Library July 22, 2022

Java Double isInfinite() method

The isInfinite() method of Java Double class will return true if the magnitude of the argument specified is infinitely large, else it will return false.

Syntax

Parameters

1.NA

2.v- This is the double value which is tested.

Return value

The isInfnite() method returns true if the value of argument passed is positive/negative infinity, otherwise returns false.

Example 1

  public class Double_isInfiniteMethodExample1 {        public static void main(String[] args) {            double d1 = 578648.67f;            Double d2 = new Double(d1/0);               //isInfinite will return true for infinity values            System.out.println(d2+” value for isInfinite() method is : ” +Double.isInfinite(d2));               //isFinite method will return false as f1/0 is infinity            System.out.println(d2+” value for isFinite() method is   : “+Double.isInfinite(d2));             }        }  

Test it Now

Output:

Infinity value for isInfinite() method is : true  Infinity value for isFinite() method is   : false

Example 2

  public class Double_isInfiniteMethodExample2 {        public static void main(String[] args) {            // will return false            Double d1 = new Double(0X7f800000);            System.out.println(“1. “+d1+” value = ” + Double.isInfinite(d1));            //will return false            Double d2 = new Double(76E-43);            System.out.println(“2. “+d2+” value = ” + Double.isInfinite(d2));            //will return false for NaN            Double d3 = new Double(0.0/0.0);            System.out.println(“3. “+d3+” value = “+Double.isInfinite(d3));            //will return true for negative infinity            Double d4 = new Double(-3723.93/0.0);            System.out.println(“4. “+d4+” value = “+Double.isInfinite(d4));          }    }  

Test it Now

Output:

1. 2.13909504E9 value = false  2. 7.6E-42 value = false  3. NaN value = false  4. -Infinity value = true

Example 3

  public class Double_isInfiniteMethodExample3 {        public static void main(String[] args) {            Double d1 = new Double(76434763746.82468746746874827);            //static isInfinite() method            boolean b1=Double.isInfinite(d1);            System.out.println(“1. “+d1+” value = “+b1);            double d2 = 27.827;            //also be called inside println function            System.out.println(“2. “+d2+” value = “+Double.isInfinite(d2));                double d3= Double.POSITIVE_INFINITY;            System.out.println(“3. “+d3+ ” value = ” +Double.isInfinite(d3));                double d4= Double.NEGATIVE_INFINITY;            System.out.println(“4. “+d4+ ” value = ” +Double.isInfinite(d4));                double d5=Double.NaN;            System.out.println(“5. “+d5+ ” value = ” +Double.isInfinite(d5));        }    }  

Test it Now

Output:

1. 7.643476374682469E10 value = false  2. 27.827 value = false  3. Infinity value = true  4. -Infinity value = true  5. NaN value = false
