Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("-333.3454");

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

    // perform plus on bg1 using mc
    BigDecimal bg2 = bg1.plus(mc);

    System.out.println(bg2);/*from   w  w  w .  j a v  a  2s .  com*/
}

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("99.8");

    MathContext mc = new MathContext(2);

    BigDecimal bg3 = bg1.divideToIntegralValue(bg2, mc);

    System.out.println(bg3);/* w ww . j  a  v a  2  s  . co  m*/
}

From source file:Main.java

public static void main(String[] args) throws Exception {
