Please anyone give your valuable thoughts about above

"NaN" stands for "Not a Number". "NaN" is produced if a floating point operation has some input parameters that cause the operation to produce some undefined result. For example, 0.0 divided by 0.0 is arithmetically undefined. Taking the square root of a negative number is also undefined.

0.0 / 0.0 -> NaN
Math.sqrt(-2.0) -> NaN


Refer The following example:

public class TestNaN {
/**
* To Test When NaN and Infinity is displayed from a Java Program
*/
public static void main(String[] args) {
System.out.println("The Value of 0.0 / 0.0 is : " + 0.0/0.0); //displays NaN
System.out.println("The Value of 1.0 / 0.0 is : " + 1.0 / 0.0);//displays Infinity
}
}
