Java - Float Class toHexString() Method

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

Float class toHexString() method

toHexString() method is available in java.lang package.
toHexString() method is used to represent a hexadecimal string of the given parameter [value] of single-precision floating-point type.
toHexString() 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.
toHexString() method does not throw an exception at the time of conversion from float to Hexadecimal string.

Syntax

public static String toHexString (float value);

Parameters

float value – represents the float value to be converted.

Return Value

The return type of this method is String, it returns the hexadecimal string of the given parameter that represent the float value.

Example

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

public class ToHexStringOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        float f1 = 10.0f;
        float f2 = 20.0f;
        float f3 = 30.0f;
        float f4 = Float.MAX_VALUE;
        float f5 = Float.MIN_VALUE;

        // Float instance creation
        Float value = new Float(f1);

        // It represents hexadecimal string of the given
        // float type f2 argument
        String s = value.toHexString(f2);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(f2): " + s);

        // It represents hexadecimal string of the given
        // float type f3 argument
        s = value.toHexString(f3);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(f3): " + s);

        // It represents hexadecimal string of the given
        // float type f4 argument
        s = value.toHexString(f4);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(f4): " + s);

        // It represents hexadecimal string of the given
        // float type f5 argument
        s = value.toHexString(f5);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(f5): " + s);
    }
}

Output

value.toHexString(f2): 0x1.4p4
value.toHexString(f3): 0x1.ep4
value.toHexString(f4): 0x1.fffffep127
value.toHexString(f5): 0x0.000002p-126
