Question

There are still some questions unanswered. Write a program that tests these occurances to learn more about formatting. Submit the code and your answers.

What happens when:

You have more digits than your format describes.
(ie. 438.978 and "##.##")

You have fewer digits than your format describes

You remove decimal places, does the formatter round the number?

You use a string instead of a literal value to represent the format description (String format = "##.#"; DecimalFormat(format);)

Please use the java language. Thanks!!!

Explanation / Answer

Hi, Please find my answer for all questions.

Please let me know in case of any issue.

import java.text.DecimalFormat;

public class DecimalF {

   public static void main(String[] args) {

       String format = "##";

       DecimalFormat df = new DecimalFormat(format);

       double d = 438.478;

       System.out.println(df.format(d));

   }

}

/*

1. You have more digits than your format describes. (ie. 438.978 and "##.##")

Answer: it round up to specified number decimal point

for => 438.978 and "##.##" => 438. 98

2. You have fewer digits than your format describes

   Answer: It print the number itself

   for => 438.978 and "##.#######" => 438. 978

3. You remove decimal places, does the formatter round the number?

   It print the number

   for => 438 and "##.##" => 438

   If you remove decimal place from formatter then it rounds up decimal point to whole number

   for for => 438.978 and "##" => 439

   for for => 438.478 and "##" => 438

   for for => 438.778 and "##" => 439
