Java Float toHexString() Method

The toHexString() method of Java Float class returns a hexadecimal string corresponding to the argument passed(float argument).

The result is:

String “NaN”, if the argument passed is NaN.
String representing sign and absolute value (magnitude) of the float parameter.

Syntax:

Parameters:

f – This is the float argument to be converted.

Return Value:

The toHexString() method returns a hex string illustration of the float argument.

Example 1

  public class FloatToHexStringExample1 {       public static void main(String[] args) {           Float f1 =7823764.8374f;          String f2 = Float.toHexString(f1);          System.out.println(“1. Hex String = “+f2);          //passing negative numbers          Float f3 = -6789564f;          System.out.println(“2. Hex String = “+Float.toHexString(f3));          Float f4= 0.98822f;          System.out.println(“3. Hex String = “+Float.toHexString(f4));        }  }

Output:

1. Hex String = 0x1.dd8654p22  2. Hex String = -0x1.9e66fp22  3. Hex String = 0x1.f9f7f8p-1

Example 2

  public class FloatToHexStringExample2 {        public static void main(String[] args) {            Float f1 = Float.MIN_VALUE;            String f2 = Float.toHexString(f1);            System.out.println(“1. “+f1+” converted to HexString = “+f2);              Float f3 = Float.MAX_VALUE;            String f4 = Float.toHexString(f3);            System.out.println(“2. “+f3+” converted to HexString = “+f4);              Float f5 = Float.NaN;            String f6 = Float.toHexString(f5);            System.out.println(“3. “+f5+” converted to HexString = “+f6);              Float f7 = Float.POSITIVE_INFINITY;            String f8 = Float.toHexString(f7);            System.out.println(“4. “+f7+” converted to HexString = “+f8);              Float f9 = Float.NEGATIVE_INFINITY;            String f10 = Float.toHexString(f9);            System.out.println(“5. “+f9+” converted to HexString = “+f10);        }  }  

Test it Now

Output:

1. 1.4E-45 converted to HexString = 0x0.000002p-126  2. 3.4028235E38 converted to HexString = 0x1.fffffep127  3. NaN converted to HexString = NaN  4. Infinity converted to HexString = Infinity  5. -Infinity converted to HexString = -Infinity

Example 3

  public class FloatToHexStringExample3 {        public static void main(String[] args) {            float f1 = 897.8f;            Float f2 = new Float(f1);            Float f3 = Float.toHexString(f2);            System.out.println(“Hex String = “+f3);        }    }
