import java.text.DecimalFormat;

public class NoCommaNumber {
    public static void main(String[] args) {
        double number = 1234567.89;
        DecimalFormat formatter = new DecimalFormat("#");
        String formattedNumber = formatter.format(number);
        System.out.println(formattedNumber); // 输出: 1234567.89
    }
}

public class NoCommaNumber {
    public static void main(String[] args) {
        double number = 1234567.89;
        String strNumber = String.valueOf(number);
        System.out.println(strNumber); // 输出: 1234567.89
    }
}
