    BigDecimal bg1 = new BigDecimal("100.123");
    BigDecimal bg2 = new BigDecimal("50.56");

    // subtract bg1 with bg2 using mc and assign result to bg3
    BigDecimal bg3 = bg1.subtract(bg2, mc);

    String str = "The Result of Subtraction is " + bg3;

    // print bg3 value
    System.out.println(str);/*from w  w w.  j  ava  2s  . c  o m*/
