Thread: no ending after decimal point.

How do i get my program to keep going until the end is reach of a number? For example 22/7 = pie. How do i get the program to keep giving numbers after pie instead of stoping after 9 or 10 decimal places?

This is what i have so far:

 System.out.println((big.setScale(BigDecimal.ROUND_CEILING)));

Problem is when i run it i get this error:

Exception in thread "main" java.lang.ArithmeticException: Rounding necessary
	at java.math.BigDecimal.divideAndRound(BigDecimal.java:1452)
	at java.math.BigDecimal.setScale(BigDecimal.java:2406)
	at java.math.BigDecimal.setScale(BigDecimal.java:2449)
	at pie.Pie.main(Pie.java:27)
Java Result: 1

I thought ROUND_CEILING was supposed to get rid of needing to round?

import java.lang.Math;
 import java.math.BigDecimal;
 import java.text.NumberFormat;
 import java.util.*;
/**
 *
 * 
 */
public class Pie {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
    double num = 22;
    double num2 = 7;
   double total = num/num2;
   BigDecimal big = new BigDecimal(total);
 
 
 
        System.out.println((big.setScale(BigDecimal.ROUND_CEILING)));    // TODO code application logic here
    }
}

thats what i have that is giving the error

I dont want it to round. I want the pie to continue forever until i shut down the program.

I thought big.setscale(BigDecimal.ROUND_CIELING) would continue to count after the decimals with no set length.

the output = 2

It enters a lot of 0's. It does not continue answering the equation tho. Why is that?
