How can I divide properly using BigDecimal

Question

My code sample:

import java.math.*; 

public class x
{
  public static void main(String[] args)
  {
    BigDecimal a = new BigDecimal("1");
    BigDecimal b = new BigDecimal("3");
    BigDecimal c = a.divide(b, BigDecimal.ROUND_HALF_UP);
    System.out.println(a+"/"+b+" = "+c);
  }
}

The result is: 1/3 = 0

What am I doing wrong?

Answer 1

You havent specified a scale for the result. Please try this

import java.math.*; 

    public class x
    {
      public static void main(String[] args)
      {
        BigDecimal a = new BigDecimal("1");
        BigDecimal b = new BigDecimal("3");
        BigDecimal c = a.divide(b,2, BigDecimal.ROUND_HALF_UP);
        System.out.println(a+"/"+b+" = "+c);
      }
    }

this will give the result as 0.33. Please read the API
