    double r = 3.1234567;
    int decimalPlace = 2;
    BigDecimal bd = new BigDecimal(r);
    bd = bd.setScale(decimalPlace, BigDecimal.ROUND_UP);
    r = bd.doubleValue();

}

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg = new BigDecimal("1234");

    // assign the converted value of bg to d
