Usage

From source file:Main.java

public static void main(String[] args) {

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

    // assign value to bg1
    BigDecimal bg1 = new BigDecimal("123.1234");

    // assign negate value of bg1 to bg2 using mc
    BigDecimal bg2 = bg1.negate(mc);

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

From source file:Main.java

public static void main(String[] args) {

    MathContext mc = new MathContext(2); // 2 precision

    BigDecimal bg1 = new BigDecimal("100.123");
    BigDecimal bg2 = new BigDecimal("50.56");

    // subtract bg1 with bg2 using mc and assign result to bg3
    BigDecimal bg3 = bg1.subtract(bg2, mc);

    String str = "The Result of Subtraction is " + bg3;

    // print bg3 value
    System.out.println(str);//from w w w. j a v a 2s  .  c o m
}

From source file:Main.java

    BigDecimal bg1 = new BigDecimal("123.1234");

    // assign absolute value of bg1 to bg2 rounded to 2 precision using mc
    BigDecimal bg2 = bg1.abs(mc);

    // assign absolute value of bg1 to bg3 rounded to 4 precision using mc1
    BigDecimal bg3 = bg1.abs(mc1);
