Java - Float intBitsToFloat(int) method



Description

The Java 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 1

The following example shows the usage of Float intBitsToFloat() method to get a float value from a given bit representation. We've printed three float values based on given bit representations.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {
  
      /* returns the float value corresponding to a given bit representation */
      System.out.println(Float.intBitsToFloat(6757689));
      System.out.println(Float.intBitsToFloat(0x7f800000));  
      System.out.println(Float.intBitsToFloat(0xff800000));  
   }
} 

Output

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

9.469539E-39
Infinity
-Infinity

Example 2

The following example shows another usage of Float intBitsToFloat() method to get a float value from a given bit representation. We've printed a float value based on given bit representation.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {
  
      /* returns the float value corresponding to a given bit representation */
      System.out.println(Float.intBitsToFloat(1098173645)); 
   }
} 

Output

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

15.3

Example 3

The following example shows the usage of Float intBitsToFloat() method to get a float value from a given bit representation. We've printed a float value based on given bit representations.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {
  
      /* returns the float value corresponding to a given bit representation */
      System.out.println(Float.intBitsToFloat(-1049310003)); 
   }
} 

Output

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

-15.3
