Description

The java.lang.Float.intBitsToFloat() method returns the float value corresponding to a given bit representation. The argument is considered to be a representation of a floating-point value according to the IEEE 754 floating-point "single format" bit layout.It includes the following important points:

  • If the argument is 0x7f800000, the result is positive infinity.
  • If the argument is 0xff800000, the result is negative infinity.
  • If the argument is any value in the range 0x7f800001 through 0x7fffffff or in the range 0xff800001 through 0xffffffff, the result is a NaN.

Declaration

Following is the declaration for java.lang.Float.intBitsToFloat() method

public static float intBitsToFloat(int bits)

Parameters

  • bits -- This is an integer.

Return Value

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

Exception

  • NA

Example

The following example shows the usage of java.lang.Float.intBitsToFloat() method.

package com.tutorialspoint;

import java.lang.*;

public class FloatDemo {

   public static void main(String[] args) {

     Float f = new Float("2.50f");
   
     /* returns the floating-point value with the same bit pattern */
     System.out.println(f.intBitsToFloat(123));
     System.out.println(f.intBitsToFloat(0x7f800000));  
     System.out.println(f.intBitsToFloat(0xff800000));  
   }
}   

Let us compile and run the above program, this will produce the following result:

1.72E-43
Infinity
-Infinity
