Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("123.123456");

    // set scale of bg1 to 6 in bg2
    BigDecimal bg2 = bg1.setScale(6);

    String str = "The value of " + bg1 + " after changing the scale to 6 is " + bg2;

    System.out.println(str);//w  w w . ja va 2  s  .c  om
}

From source file:Main.java

public static String MybigdecimalToString(BigDecimal myBigD) {
    myBigD = myBigD.setScale(2);
    DecimalFormat df = new DecimalFormat();
    df.setMaximumFractionDigits(2);//  w  ww.  ja v  a2  s .com
    df.setMinimumFractionDigits(0);
    return df.format(myBigD);
}
