Find ceiling value of a number using Math.ceil
This java example shows how to find a ceiling value of a number using ceil method
of Java Math class. ceil method returns the smallest interger which is not
less than the value.
*/
public class FindCeilingExample {
public static void main(String[] args) {
/*
* To find a ceiling value, use
* static double ceil(double d) method of Math class.
*
* It returns a smallest integer which is not less than the argument value.
*/
//Returns the same value
System.out.println(Math.ceil(10));
//returns a smallest integer which is not less than 10.1, i.e. 11
System.out.println(Math.ceil(10.1));
//returns a smallest integer which is not less than 5.5, i.e. 6
System.out.println(Math.ceil(5.5));
//in this case it would be -20
System.out.println(Math.ceil(-20));
//it returns -42 not -43. (-42 is grater than 42.4 :) )
System.out.println(Math.ceil(-42.4));
//returns 0
System.out.println(Math.ceil(0));
}
}
/*
Output would be
10.0
11.0
6.0
-20.0
-42.0
0.0
