Thread: Formatting this number.

i would like this tiny bit of help.

i built this little program that calculates stuff(unimportant what it calculates).

but sometimes when its dividing or multiplying big numbers, it displays it in the scientific notification.
like it should display: 10000000(10 million)
but it displays: 1.0E7.

how can i fix this? i dont want it to display it in the scientific notifitcation.

code:

if(e.getSource()==b1 && box.getSelectedItem()==fish[8]){
				String xp1 = txt1.getText();
				int xp2 = Integer.parseInt(xp1);
				String xp3 = txt2.getText();
				int xp4 = Integer.parseInt(xp3);
				double xpleft = xp4 - xp2 ;
				double fishleft = xpleft / 350;
				JOptionPane.showMessageDialog(null, "XP left: "+"\t"+xpleft+"\n"+box.getSelectedItem()+" left: "+"\t"+fishleft+"\n"+"\n"+"NOTE: always round these numbers."+"\n"+"example: fish left: 1,87 = fish left: 2.", "Fishing Calculator", JOptionPane.INFORMATION_MESSAGE);

Format the string. There is a format() method for this. The options available in the format string are described in the Formatter class.

public class FormatEg {
    public static void main(String[] args) {
        double big = 12345678.9;
        String toDisplay = String.format("A big number: %.0f", big);
        System.out.println(toDisplay);
    }
}

Also at j-f.org: i just can't fix this

Please try BigDecimal as well:
double big = 123456789.6;
System.out.println((new BigDecimal(Double.toString(big))).toPlainString()) ;
//output:
//123456789.6
