Java Float intBitsToFloat() method

The intBitsToFloat() method of Java Float class returns the float value in respect to a given bit representation. The argument which passed is considered to be a representation of a floating-point value according to the IEEE 754 floating-point ‘single format’ bit layout.

Syntax:

Parameters:

In this method, bits parameter is passed which is an integer value.

Return Value:

This method returns the floating-point value with the same bit pattern.

The result returned is positive infinity, if the argument passed is 0X7f800000.
The result returned is negative infinity, if the argument passed is 0Xff800000.
The result returned is Nan, if the argument passed is in the range between 0x7f800001 to 0x7fffffff or in the range between 0xff800001 to 0xffffffff.

Example 1

  public class FloatIntBitsToFloatExample1 {        public static void main(String[] args) {                 int value1=76;                 Float f2=Float.intBitsToFloat(value1);               System.out.println(“Float value after conversion = “+f2);                 int value2=4866;               //method can be called directly in println function               System.out.println(“Float value after conversion = “+Float.intBitsToFloat(value2));                 //passing negative integer               int value3=-4756;          System.out.println(“Float value after conversion = “+Float.intBitsToFloat(value3));        }  }  

Test it Now

Output:

Float value after conversion = 1.06E-43  Float value after conversion = 6.819E-42  Float value after conversion = NaN

Example 2

  public class FloatIntBitsToFloatExample2 {        public static void main(String[] args) {                  //result returned is positive infinity         int value1=  0X7f800000;          System.out.println(value1+ ” value = “+Float.intBitsToFloat(value1));          // result returned is negative infinity          int value2=0Xff800000;          System.out.println(value1+ ” value = “+Float.intBitsToFloat(value2));  }  }  

Test it Now

Output:

2139095040 value = Infinity  2139095040 value = -Infinity

Example 3

  import java.util.Scanner;    public class FloatIntBitsToFloatExample3 {      public static void main(String[] args) {            Scanner scanner = new Scanner(System.in);          System.out.println(“Enter first integer”);          int value1=scanner.nextInt();          System.out.println(“1. Float value = “+Float.intBitsToFloat(value1));            System.out.println(“Enter Second integer”);          int value2=scanner.nextInt();          System.out.println(“2. Float value = “+Float.intBitsToFloat(value2));        }  }  

Test it Now

Output:

Enter first integer  567  1. Float value = 7.95E-43    Enter Second integer  67  2. Float value = 9.4E-44
