    public static void main(String[] args) {

        // create 3 BigDecimal objects
        BigDecimal bg1, bg2, bg3;

	MathContext mc = new MathContext(4); // 4 precision

        bg1 = new BigDecimal("2.310");
        bg2 = new BigDecimal("4.620");

        // multiply bg1 with bg2 using mc
	bg3 = bg1.multiply(bg2, mc);
