How do I convert '2.0E8' to regular number?

I would like to convert from and scentific number
2.0E8 ---> 200000000.0
Is there any classes that I can use to detect scientific number and then convert it to
a real number?
Thank you.

I think java.text.DecimalFormat is what you are looking for.

  • How can i convert the HTML information in XML form to a PDF?

    Hi does any body know how can i convert the content of an HTML field in a XML Form in a regular text to include in a PDF in a Java program?

    Hi ,
    On the tool bar you have an option "Browser" which is next to "HTML Editor" .
    You know that for using these elements wo have to map them with Data Schema.
    Step by step
    1. In data Model Under Data Schema Add a child and name it Read_More.
    2. In the left hand corner ,click on tab Type and from the drop down select "rid"
    3.Click on the "Browser" from the toolbar (as told earlier) and drag and drop it on the form.
    4. Drag the Data schema which u have made(Read_more) and drop it on the browser on form. On right hand side u will se the mapping done.
    5.Click on the "Browser" which is there in the form and on the right hand side of the form u will see the property window.
    6.In property window change the value of action property to "Item Entry point"
    7. Repeat step 3 and 4 in Render and show form but using "label" nad not browser.
    Do not forget to add Save button in Edit Form.
    This will solve your problem.
    PS:Rewards Point Please.

  • How do I Convert PDF file in browser to something else?

    Hi All
      How can I convert a PDF file coming up in browser to something else so I can print it on my epson printer. I looked in other forums and found something I tried, where you downloaded a converter, and I converted in to Jpeg among some other options it had, and printer would still not work, printer works on regular websites or on my notepad etc. but won't do the PDF file or would not print once I converted it to other things, can anyone help me. Thank you

    I don't understand why you cannot print that PDF document.
    What happens when you click on the Print icon on the upper-left side of the Adobe Reader browser plugin

  • How can I convert my existing tunes to work on an MP3 player?

    I have purchased a CBC radio show from Itunes and want to put it on an MP3 player. It appears the file format is not compatable. How can I convert the existing files to MP3 format??
    Thanks.

    If it has Apple FairPlay DRM on it, you can't simply "convert it" to MP3. You must first burn it to a CD, then import it again into iTunes. Make sure your import settings have MP3, and match the native bit-rate of the original track.
    If it's a regular AAC audio file, then simply change your import settings to MP3, then right-click the file and choose "Create MP3 Version."

  • How do I Convert Music Files to .Was or AIFF?

    I want to burn a CD that will play on an regular CD player. How can I convert the file format of songs in my iTunes to a format that will work on such a CD player?

    This is how you create audio CDs. If it's not working then there can be a few reasons why it's not.
    burned the disk choosing "Audio CD" and the resulting CD would not play in a "regular" CD player.
    Does this "regular CD player" play CD-R? Have you played other burned CDs in it?
    Have you tried this burned CD in a different CD player? Pop it in a DVD player and see if it works.
    Does this CD play in iTunes?
    Are there any other suggestions?
    Try to burn at a slower speed.
    Try different discs.

  • I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?

    I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?

    The application Acrobat provides no language translation capability.
    If you localize the language for OS, MS Office applications, Acrobat, etc to the desired language try again.
    Alternative: transfer a copy of content into a web based translation service (Bing or Google provides a free service).
    Transfer the output into a word processing program that is localized to the appropriate language.
    Do cleanup.
    Be well...

  • How can I convert an InputStream to a FileInputStream ???

    How can I convert an InputStream to a FileInputStream ???

    Thanks for you reply, however, I am still stuck.
    I am trying to convert my application (which runs smoothly) to a signed applet. The following is the original (application) code:
    private void loadConfig() {
    String fileName = "resources/groupconfig";
    File name = new File(fileName);
    if(name.isFile()) {
    try {
         ObjectInputStream in = new ObjectInputStream(new FileInputStream(fileName));
         pAndGConfig = (PAGroupsConfig)in.readObject();
         in.close();
         return;
    } catch(ClassNotFoundException e) {
         System.err.println("++ERROR: "+e);
    } catch(IOException e) {
         System.err.println("++ERROR: "+e);
    System.out.println("Can't find file: " + fileName);
    Because all code and resources now reside in a Jar file (for the signed applet), I must use the following line to access the resources:
    InputStream is = this.getClass().getResourceAsStream(fileName);
    I then need to convert the 'InputStream' to 'ObjectInputStream' or 'FileInputStream' so that I can work with it.
    I would be very grateful if you could help shed some light on the matter - Cobram

  • I changed from i iphone 5 back to a iphone 4.. now my itunes does not recognise that i have a iphone 4! how do i convert my last back up (on iphone 5) to my new iphone 4?

    i changed from i iphone 5 back to a iphone 4.. now my itunes does not recognise that i have a iphone 4! how do i convert my last back up (on iphone 5) to my new iphone 4?

    In your case you can only restore from a backup that has been created with the same iOS version. An iPhone 4 can only run 7.1.2, and, unless your iPhone 5 did not run the same version, you can't use a newer iOS backup of the 5 on the iPhone 4
