Number Class floatValue() method

  • floatValue() method is available in java.lang package.
  • floatValue() method is used to return the value denoted by this Number object converted to type float (by casting) and it may involve in rounding or truncation.
  • floatValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • floatValue() method does not throw an exception at the time of conversion from Number to float.

Syntax:

    public abstract float floatValue();

Parameter(s):

  • It does not accept any parameter.

Return value:

The return type of this method is float, it returns a converted (from type Number to float) value represented by this Number object.

Example:

// Java program to demonstrate the example 
// of floatValue() method of Number class

public class FloatValueOfNumberClass {
    public static void main(String[] args) {
        // Variables initialization
        int i1 = 10;
        double d1 = 20.62;

        // It returns float value denoted by this object
        // and converted to a float by calling i.floatValue()
        Integer i = new Integer(i1);

        // Display i result
        System.out.println("i.floatValue(): " + i.floatValue());

        // It returns float value denoted by this object
        // and converted to a float by calling d.floatValue()
        Double d = new Double(d1);

        // Display d result
        System.out.println("d.floatValue(): " + d.floatValue());
    }
}

Output

i.floatValue(): 10.0
d.floatValue(): 20.62
