Find floor value of a number using Math.floor

/*
Find floor value of a number using Math.floor
This java example shows how to find a floor value of a number using floor method
of Java Math class. floor method returns the largest interger which is not grater
than the value.
*/
public class FindFloorValueExample {
public static void main(String[] args) {
/*
* To find a floor value, use
* static double floor(double d) method of Math class.
*
* It returns a largest integer which is not grater than the argument value.
*/
//Returns the same value
System.out.println(Math.floor(70));
//returns largest integer which is not less than 30.1, i.e. 30
System.out.println(Math.floor(30.1));
//returns largest integer which is not less than 15.5, i.e. 15
System.out.println(Math.floor(15.5));
//in this case it would be -40
System.out.println(Math.floor(-40));
//it returns -43.
System.out.println(Math.floor(-42.4));
//returns 0
System.out.println(Math.floor(0));
}
}
/*
Output would be
70.0
30.0
15.0
-40.0
-43.0
0.0
