Java Number floatValue() Method

The floatValue() is a method of Java Number class which returns the float equivalent value of the specified Number object. It may also involve in rounding or truncation of the specified Number value.

Syntax:

Following is the declaration of floatValue() method:

Parameter:

DataType	Parameter	Description
NA	NA	It does not accept any parameter.

Returns:

The floatValue() method will return the numeric value represented by this object after conversion to type float.

Exceptions:

Compatibility Version:

Java 1.0 and above

Example 1

public class NumberFloatValueExample1 {
	public static void main(String[] args) {		
		//Input Number with Integer DataType and Double DataType
            Integer a = 2454;
            Double b = 86549.9875690;
            //Print the Number values as float
            System.out.println("Value : "+a.floatValue());       
            System.out.println("Value : "+b.floatValue());        
		}
}

Output:

Value : 2454.0
Value : 86549.984

Example 2

import java.util.Scanner;
public class NumberFloatValueExample2 {
	public static void main(String[] args) {		
		Scanner readInput = new Scanner(System.in);
		System.out.print("Enter The Desired Input Value: ");		
		//Input Number
            Integer i = readInput.nextInt();            
            //Print the value as float
            System.out.println("The Float Value is: "+i.floatValue()); 
            readInput.close();
		}
}

Output:

Enter The Desired Input Value: 123ABCD
