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 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
