In this tutorial, we are going to write a Java program to use double type value or variable data type in Java Programming with practical program code and step-by-step full complete explanation.

Java program using double variable


Java program using a double variable.

 
class Main
{
    public static void main(String args[])
    {
        double i = 34.32; //given number
        System.out.println("Small Integer not greater than the number : "+Math.ceil(i));
        System.out.println("Given Number : "+i);
        System.out.println("Largest Integer not greater than the number : "+Math.floor(i));
    }
}


Output

 
Small Integer not less than the number : 35.0
Given Number : 34.32
Largest Integer not greater than the number : 34.0
