Usage

From source file:Main.java

public static void main(String[] args) {
    MathContext mc = new MathContext(3); // 3 precision

    BigDecimal bg = new BigDecimal("1234E4", mc);

    System.out.println(bg.toString());
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int decimalPlaces = 2;
    BigDecimal bd = new BigDecimal("123456789.0123456890");

    bd = bd.setScale(decimalPlaces, BigDecimal.ROUND_DOWN);
    String string = bd.toString();
