Java - Float Class floatToIntBits() Method

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

Float class floatToIntBits() method

floatToIntBits() method is available in java.lang package.
floatToIntBits() method follows IEEE 754 floating-point standards and according to standards, it returns the bits representation that denotes floating-point value.
floatToIntBits() 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.
floatToIntBits() method does not throw an exception at the time of representing bits.

Syntax

public static int floatToIntBits(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 value "0x7fc00000".

Example

// Java program to demonstrate the example 
// of floatToIntBits (float value)
// method of Float class

public class FloatToIntBitsOfFloatClass {
    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.floatToIntBits(value1)
        int result1 = Float.floatToIntBits(value1);

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

        // Display result1,result2 values
        System.out.println("Float.floatToIntBits(value1): " + result1);
        System.out.println("Float.floatToIntBits(value2): " + result2);
    }
}

Output

value1: 18.2
value2: 19.2
Float.floatToIntBits(value1): 1100061082
Float.floatToIntBits(value2): 1100585370
