Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("1.230");
    BigDecimal bg2 = new BigDecimal("4.560");

    BigDecimal bg3 = bg1.multiply(bg2);

    System.out.println(bg3);//w ww. j  a va 2s  . c om
}

From source file:BigDec.java

public static void main(String args[]) {

    System.out.println("Annual rate : " + rate);
    System.out.println("Monthly rate: " + monthlyRate);
    BigDecimal balance = new BigDecimal("10000.0000");
    for (int i = 0; i < 12; i++) {
        BigDecimal interest = balance.multiply(monthlyRate);
        balance = balance.add(interest);
        System.out.println("Balance: " + balance);
