Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("16");
    BigDecimal bg2 = new BigDecimal("3");

    // divide bg1 with bg2 rounding up
    BigDecimal bg3 = bg1.divide(bg2, RoundingMode.UP);

    System.out.println(bg3);//from   w  ww .  j  a va2s . com
}

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("123456");
    BigDecimal bg2 = new BigDecimal("3");

    MathContext mc = new MathContext(2);

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

    System.out.println(bg3);/*from   www.  j  ava 2s  .c o  m*/
}

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("16");
    BigDecimal bg2 = new BigDecimal("3");

    // divide bg1 with bg2
    // 0 specifies BigDecimal.ROUND_UP
    BigDecimal bg3 = bg1.divide(bg2, BigDecimal.ROUND_UP);

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

From source file:Main.java
