Java - Float Class floatToRawIntBits() Method

Float class floatToRawIntBits() method: Here, we are going to learn about the floatToRawIntBits() method of Float class with its syntax and example. By Preeti Jain Last updated : March 21, 2024

Float class floatToRawIntBits() method

floatToRawIntBits() method is available in java.lang package.
floatToRawIntBits() method follows IEEE 754 single-precision floating-point standards and according to standards, it returns the bits that denote floating-point value along with preserving NaN value.
floatToRawIntBits() method is a static method, it is accessible with the class name too and, if we try to access the method with the class object then also we will not get an error.
floatToRawIntBits() method does not throw an exception at the time of representing bits along with preserving NaN (Not a Number).

Syntax

public static int floatToRawIntBits(float f);

Parameters

float f – represents the single precision floating point value.

Return Value

The return type of this method is float, it returns the bits that represent the single precision floating-point value.

If we pass "positive infinity", it returns the value "0x7f800000".
If we pass "negative infinity", it returns the value "0xff800000".
If we pass "NaN", it returns the actual NaN values (i.e. it does not collapse all the bit encoding a NaN to a "basic" NaN value).

Example

// Java program to demonstrate the example 
// of floatToRawIntBits (float f)
// method of Float class

public class FloatToRawIntBits {
    public static void main(String[] args) {
        // Variables initialization
        float value1 = 18.20f;
        float value2 = 19.20f;

        // Display value1,value2 values
        System.out.println("value1: " + value1);
        System.out.println("value2: " + value2);


        // It returns the bits denoted by the single precision 
        // floating point argument by calling 
        // Float.floatToRawIntBits(value1)
        int result1 = Float.floatToRawIntBits(value1);

        // It returns the bits denoted by the single precision 
        // floating point argument by calling 
        // Float.floatToRawIntBits(value2)
        int result2 = Float.floatToRawIntBits(value2);

        // Display result1,result2 values
        System.out.println("Float.floatToRawIntBits(value1): " + result1);
        System.out.println("Float.floatToRawIntBits(value2): " + result2);
        System.out.print("Float.floatToRawIntBits(NaN): ");
        System.out.println(Float.floatToRawIntBits(5.0f % 0f));
    }
}

Output

value1: 18.2
value2: 19.2
Float.floatToRawIntBits(value1): 1100061082
Float.floatToRawIntBits(value2): 1100585370
Float.floatToRawIntBits(NaN): 2143289344
