Java Float floatToRawIntBits() method

The floatToRawIntBits() method of Java Float class returns the specified floating-point value according to the IEEE 754 floating-point 'single format' bit layout.

Syntax:

Parameters:

A float type parameter (value) is passed. Here value is a floating-point number.

Return Value:

The floatToRawIntBits(float value) method of Float class returns the bits of the given floating-point number.

If positive infinity is passed as an argument, it will return 0x7f800000.
If negative infinity is passed as an argument, it will return 0xff800000.
If NaN is passed as an argument, it will return the actual integer of NaN value. It is different from floatIntBits() method as this method does not collapse all the bits patterns encoding a NaN to a single canonical Nan value.

Example 1

public class Float_floatToRawIntBitsMethod_Example1 {

    public static void main(String[] args){

             //returns the bits that represent the floating-point number
                Float obj=9.8f;
        System.out.println(obj +" value in  Raw int bits = " + Float.floatToRawIntBits(obj));


             //0/0 argument is NaN,
                Float obj1 = 0.0f/0.0f;
        System.out.println(obj1 + " value in Raw int bits = " + Float.floatToRawIntBits(obj1));



            // positive integer divided by zero gives infinity
                Float obj2 = obj/0;
        System.out.println(obj2 + " value in Raw int bits = " + Float.floatToRawIntBits(obj2));

            // negative integer divided by zero gives negative infinity
                Float obj3 = -obj/0.0f;
        System.out.println(obj3 + " value in Raw int bits = " + Float.floatToRawIntBits(obj3));



            }
        }

Output:

9.8 value in  Raw int bits = 1092406477
NaN value in Raw int bits = 2143289344
Infinity value in Raw int bits = 2139095040
-Infinity value in Raw int bits = -8388608

Example 2

public class Float_floatToRawIntBitsMethod_Example2 {

    public static void main(String[] args) {

       //passing negative value
        float f1=-658756.5756756f;

        Float f2= new Float(-6547.65776f);

        //either call floatToRawIntBits() method this way
        int f3=Float.floatToRawIntBits(f1);
        System.out.println(f1+"value in Raw Int bits = "+f3);

        //either call it directly inside println
        System.out.println(f2+" value in Raw Int bits = "+Float.floatToIntBits(f2));
    }
}

Test it Now

Output:

-658756.56value in Raw long bits = -920595383
-6547.6577 value in Raw long bits = -976446141

Example 3

public class Float_floatToRawIntBitsMethod_Example3 {


    public static void main(String[] args) {

        //passing negative value
        float f1=-656.67756f;
        Float_floatToRawIntBitsMethod_Example3  obj = new Float_floatToRawIntBitsMethod_Example3();


        //Converting negative float to Raw Int Bits
        Float f2= Float.floatToRawIntBits(f1);
        System.out.println(f1+" value in long bits = "+f2);
    }
}

Test it Now

Output:

Error:(14, 42) java: incompatible types: int cannot be converted to java.lang.Float

Here, we are converting it into int bits and then putting it into float without an explicit cast. Either we should type cast it or should directly call this method in println function otherwise we will get an error.
