I cannot find any pattern rounding off doubles in an array. I am trying to make a program that will input a double like grades,money etc., and round it off in a whole number.

Have you tried Math.round() ?

import java.lang.*;

 

public class MathDemo {

 

   public static void main(String[] args) {

 

      // get two float numbers

      float x = 1654.9874f;

      float y = -9765.134f;

 

      // find the closest int for these floats

      System.out.println("Math.round(" + x + ")=" + Math.round(x));

      System.out.println("Math.round(" + y + ")=" + Math.round(y));

 

   }

}
