Java decimal precision problem

I have a problem. I have to print in long decimal places

Solution

In C or Java, you won't get so much decimal precision in IEEE754 binary floating point numbers Your best choice is to use BigDecimal and perform arithmetic with specific precision For example:

import java.math.*;

public class Test {
    public static void main(String[] args) throws Exception {
        MathContext context = new MathContext(30);
        BigDecimal result = BigDecimal.ONE.divide(new BigDecimal(3),context);
        System.out.println(result.toPlainString());
    }
}
