Usage

From source file:Main.java

public static void main(String[] args) {

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

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

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

    System.out.println(bg3);/*from w ww  . j  av a2  s.co  m*/
