parseDouble question

[Melinda Savoy]

I could not find the answer to my question in the SEARCH feature so I thought I'd post here.

Here is my code:

String t = ("17514000.00");

double dblTest = Double.parseDouble(t);
System.out.println(dblTest);

The output comes out as = 1.7514E7

I need it come out as = 17514000.00

I guess I thought the parseDouble method would help me with this. Any suggestions or direction would be appreciated.

Thanks.

You might check out DecimalFormat

You could also try the BigDecimal class.

import java.math.BigDecimal;
public class BigDecimalTest
{
   public static void main(String[] args)
   {
      String t = "17514000.00";      
      BigDecimal number = new BigDecimal(t);
 
      System.out.println(number.toString());
   }
}

You need to be aware of this: A double is just a number. It doesn't have any inherent format.

When you want to print a number to the screen, it has to be converted to text (digits, '1', '7', '5', etc.). When you convert a number to text, you do this using a specified format.

The method parseDouble in class Double does the opposite: it parses text and converts it to a number. As I said above, once the text is converted to a number, it's just a number, and it doesn't have a format.

If you use println to print a double, you don't specify the format which is to be used to convert the number back to text, so println uses a default format, and your number comes out as "1.7514E7".

If you want to explicitly specify how the number should be formatted, you should use a class like java.text.DecimalFormat. For example:

double d = 17514000.0;
DecimalFormat df = new DecimalFormat("########.00");
System.out.println(df.format(d));
