Ceiling. With this method, a number is always increased if it has a fractional part. It does not matter how close to the lower number the number is—it is increased by ceil().
Java program that uses Math.ceil
import java.lang.Math;
public class Program {
public static void main(String[] args) {
// Compute ceilings of these values.
double value = Math.ceil(1.1);
double value2 = Math.ceil(-0.9);
System.out.println(value);
System.out.println(value2);
}
}
Output
2.0
-0.0
