Random (number) Help

hi
can anybody help me
In the function random (number)
if for eg. number=56
then it generates any number between 0 and 56
but if want to generate numbers between 56 and 567
what should i do ?
please help me

function randomBetween(min:Number, max:Number):Number {
var randomNum:Number =
Math.round(Math.random()*(max-min)+min);

  • Need help with a JavaScript to generate random number

    Hi
    First things first. I don't know the J of JavaScript.
    When I was thinking of some readymade solution to generate a random number in Captivate, I found this on a LinkedIn forum.
    1) Add a user variable to your project called "randomNumber". It's value can be zero.
    2) Add a Text Caption with "$$randomNumber$$" in it, to check whether your script is working.
    3) Add a button to the slide. Give it an On Success Action of Execute JavaScript. Turn off it's "Continue Playing the Project" checkbox.
    4) Add the following text in the button's Script_Window:
    var objCP = document.Captivate;
    var rand = 1 + Math.floor(Math.random() * 10);
    function onButtonClick(){
    objCP.cpEISetValue('randomNumber', rand);
    onButtonClick();
    However, this is (as the poster in the forum warned) not working for Captivate 7. Can somebody please help?
    I am open for any other methods of getting the same result.
    Thanks in advance,
    Sreekanth

    Hi Sreekanth,
    When testing, make sure you are testing from a web server where the web address begins with http or https.  When setting the captivate variable "randomNumber" try this instead:
    objCP.cpEISetValue('m_VarHandle.randomNumber', rand);
    That will only work for SWF output.  If you want it to work for both HTML5 and SWF output, try this code:
    window.onButtonClick = function(){
              var rand = generateRandomNumber(1, 10);
              setCpVariable('randomNumber', rand);
    window.generateRandomNumber = function(min, max){
              var randomNum = 0;
              if(!isNaN(parseFloat(min)) && !isNaN(parseFloat(max))){
                        min = Number(min);
                        max = Number(max);
                  randomNum = Math.floor(Math.random() * (max - min + 1)) + min;
              return randomNum;
    window.setCpVariable = function (cpUserVariableName, variableValue) {
              /* Check for HTML5 vs. SWF output */
              if (typeof window.cp === 'undefined') {
                        /* We have SWF output, so Get the Captivate Object */
                        var objCp = document.getElementById('Captivate');
                        if (objCp && objCp.cpEISetValue) {
                                  /* Set the Captivate User variable with the JavaScript variable, variableValue */
                                  objCp.cpEISetValue('m_VarHandle.' + cpUserVariableName, variableValue);
              } else {
                        /* We have HTML5 output */
                        /*If variable does not exist off of the window object, then use the variables manager*/
                        if (typeof window[cpUserVariableName] === 'undefined') {
                                  if (cp.vm && cp.vm.setVariableValue) {
                                            cp.vm.setVariableValue(cpUserVariableName, variableValue);
                        } else {
                                  window[cpUserVariableName] = variableValue;
    window.onButtonClick();
    Be sure to test this from a web server or else local security will prevent the javascript from executing.
    Best,

  • Help: JSP Random Number Generator

    hello every one,
    Im trying to generate a random number using currentTimeMillis(), in Jsp, can you help me out and advice me how can this be done please.

    First you say you want a random number, then you say you want a unique one. Which is it?
    Random numbers do not normally guaruntee uniqueness.
    is there away i could use the currentTimeMillis(), What would you use it for? System.currentTimeMillis() is commonly used as a seed for a random number generator. The java.util.Random class uses it like that - take a look at that API link.
    Or if its a homework question state the exact requirement - I'm guessing here.

  • I need help with random number in GUI

    hello
    i have home work about the random number with gui. and i hope that you can help me doin this application. and thank you very much
    Q1)
    Write an application that generates random numbers. The application consists of one JFrame,
    with two text fields (see the figures) and a button. When the user clicks on the button, the
    program should generate a random number between the minimum and the maximum numbers
    entered in the text fields. The font of the number should be in red, size 100, bold and italic.
    Moreover, if the user clicks on the generated number (or around it), the color of the background
    should be changed to another random color. The possible colors are red, green blue , black ,cyan
    and gray.
    Notes:
    �&#61472;The JFrame size is 40 by 200
    �&#61472;The text fields size is 10
    this is a sample how should the programe look like.

  • Random NUMBER generator help..

    Hi all,
    i'm having issues with my random number generator i'm trying to fill my array with random numbers but i keep getting it filled with zeros.... can any one tell me what i'm doing wrong i can;t figure it out..
    for (int i =0; i < 100; i++){
                        int x=(int) (Math.random());
                        data[i] = x;
    }

    From the API "Returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0."
    So casting the value to int is always going to result in a zero value.
    You need to multiply by a value that is one larger than the value you want to be your maximum. For example:
    int x = (int)(Math.random() * 100);
    should create a random number from 0 to 99

  • How do I assign images to grid cells based on their random number value?

    Hello everyone!
         I need a good point (or shove) in the correct direction.
    Background
         I've created (with previous help from this forum) a 12 x 9 random number grid which cycles through the numbers 1 to 9 a total of twelve times each. I've then created a button which shuffles the current grid's cells each time it is clicked. I now want to use 9 images that I have imported as individual symbols into the library (I have given them each their own class titled "skin1," "skin2," ... "skin9") as cell labels or the equivalent. I have also set the images up as individual movie clips (using the .Sprite class as the extended base class but keeping the actual image class names in line with their object name, i.e. the "skin1" image is the "skin1.as" class).
    Question
         How do I assign these images to the grid cells based on their respective values (ranging from 1 to 9) and have them populate the grid each time I click the "shuffle" button? So for example, in my grid the numbers 1 through 9 randomly appear 12 times each. Every time the number 4 appears in a cell, I want it to be assigned to the image "skin4" (which is just a graphic that looks like a button and has a fancy number "4" printed on it). Below is a chunk of the code I am using to draw the grid cells with:
    // Creates a grid cell when called by generateGrid().
    private funciton drawCell(_numeral:int):Sprite
              This is the code I am currently implementing to populate the grids with (although I
              don't want to use text labels as I want to fill each grid with an image according
              to its numerical value (1 to 9).
         var _label:TextField = new TextField();
         _label.multiline = _label.wordWrap = false;
         _label.autoSize = "center";
         _label.text = String(_numeral);
         // Add numerical label to cell array.
         cellLabels.push(_label);
         var _s:Sprite = new Sprite();
         _s.graphics.lineStyle(2, 0x019000);
         _s.graphics.drawRect(30, 0, cellW, CellH);
         _s.addChild(_label);
         return _s;
         While the following isn't working code, it will hopefully demonstrate what I want to achieve inside this function so I don't have to use the above snippet for text labels:
         //This will "hopefully" create an array of all 9 images by calling their classes.      var _imageArray:Array = [skin1, skin2, skin3, skin4, skin5 , skin6, skin7, skin8, skin9];      // This is what I want to happen for each cell using the above image array:      for (i = 0; i < cells; i++)      {           if (_numeral == 1)           {                // Insert skin1 image for each instance of #1 in the grid.           }           if (_numeral == 2)           {                // Insert skin2 image for each instance of #2 in the grid.           }           ...           if (_numeral == 9)           {                // Insert skin9 image for each instance of #9 in the grid.           }      } 
         Again, I don't want to use text labels. I have a custom skin graphic that I want to go over each number on the grid based on its numerical value (1 to 9). Any help with this is much appreciated!

    kglad,
         Thank you for your help with this one. Using the code below, I have successfully populated my grid cells with the desired corresponding graphics. I noticed one thing though regarding my use of the shuffle button with this particular implementation: even though the numerical values residing in each cell get shuffled, the original images remain in the grid rather than being replaced by new ones. The first code snippet below is the revised cell drawing function including your help; the second snippet shows you my simple shuffle button function (where the problem lies, I think).
    Snippet #1:
         // Creates a grid cell when called by generateGrid().
         private function drawCell(_numeral:int):Sprite
              var _label:TextField = new TextField();
              _label.multiline = _label.wordWrap = false;
              _label.autoSize = "center";
              // Creates a label that represents the numerical value of the cell.
              cellLabels.push(_label);
              var _s:Sprite = new Sprite();
              _s.graphics.lineStyle(2, 0x019000);
              _s.graphics.drawRect(30, 0, cellW, cellH);
              // Physically adds the labels to the grid.
              _s.addChild(_label);
              // Assigns a graphic class to a cell based on its numerical value.
              var _classRef:Class = Class(getDefinitionByName("skin" + _numeral));
              // Undefined variable for holding graphic classes.
              var _image:* = new _classRef();
              // Lines the images up with the grid cells.
              _image.x = 30;
              // Physically adds a graphic on top of a cell label.
              _s.addChild(_image);
              return _s;
         So far so good (although I question needing text labels at all if they are just going to remain invisible underneath the images, but enough about that for now). This next part is the reason that the images won't shuffle with the cell values, I think.
    Snippet #2:
         // When shuffleButton is clicked, this event shuffles
         // the number array and fills the cellLabels with the new values.
         private function onButtonShuffleClick(e:MouseEvent):void
              // Shuffles the number array.
              shuffle(numbers);
              // Verifies the array has been shuffled.
              trace("After shuffle:", numbers);
              // Loop replaces old cellLabels with new number array values.
              for (var i:int = 0; i < cells; i++)
                   cellLabels[i].text = String(numbers[i]);
         As you can see, it never replaces the original images that populate the grid. I tried using the _s.removeChild(image) function but that didn't work, nor would copying/pasting some of the code from snippet #1 directly into this function as it would cause another instance of the images to be placed over top of the existing ones rather than actually swapping them out. Any continued help here is greatly appreciated!
         PS Is there a quicker method for posting code into these forums without having to type it all out by hand again (i.e. copy/paste or drag/drop from my .fla or Notepad file directly into this thread)?

  • What algorithm does Excel 2010 use for Pseudo Random Number Generation (MT19937?)

    Does Excel 2010+ use the Mersenne Twister (MT19937) algorithm for Pseudo Random Number Generation (PRNG), implemented by the RAND() function?
    This has been a nagging question for some time now, with "hints" that it indeed does.  However, a relatively thorough search turns up no definitive documentation.  The most direct indication is perhaps given by Guy Melard [Ref 9] where
    he tests Excel 2010's RAND() function using the Crush battery of tests in TestU01 by L'Ecuyer & Simard.  Melard references a "semi-official" indication that Microsoft did indeed implement MT19937 for the RAND() function in
    Excel 2010, but this reference no longer seems to be available. http://office.microsoft.com/enus/excel-help/about-solver-HP005198368.aspx?pid=CH010004571033.
    The other references below [Ref 1-10] document the history of the statistical suitability of the PRNG and probability distributions in various versions of Excel.  This includes the Wichmann-Hill PRNG implementations supposedly (arguably) used in
    Excel 2003 & 2007 for random number generation.  But still, we have no answer as to which PRNG algorithm is used in
    Excel 2010 (and 2013 for that matter).
    Microsoft indicates that RAND() has been improved in Excel 2010; Microsoft states, "...and the RAND function now uses a new random number algorithm." (see https://support.office.com/en-ca/article/Whats-New-Changes-made-to-Excel-functions-355d08c8-8358-4ecb-b6eb-e2e443e98aac). 
    But no details are given on the actual algorithm.  This is critical for Monte Carlo methods and many other applications.
    Any help would be much appreciated. Thanks.

    I found the same KB article:
    https://support.microsoft.com/en-us/kb/828795
    This was introduced (according to the article) in Excel 2003. Perhaps the references in notes 2 and 3 might help.
    The article describes combining the results of 3 generators, each similar to a Multiply With Carry (MWC) generator, but with zero carry. MWC generators do very well on the Diehard battery of randomness tests (mentioned in your references), and have
    very long periods. But using zero carry makes no sense to me.
    Combining the three generators only helps if the periods of the 3 are relatively prime (despite what the article implies). Then the period of the result will be the product of the 3 periods. But without knowing the theory behind these generators, I have
    no idea what the periods would be. The formulas for MWC generators fail here.

  • How to generate a unique random number in a MySQL db

    I'm creating a volunteer and also a separate vendor application form for an airshow. The volunteer and vendor info is stored in separate tables in a MySQL db, one row per volunteer or vendor. There will be about 100 volunteers and 50 vendors. When the application is submitted it should immediately be printed by the applicant, then signed and mailed in. This past year we had problems with some people who didn't immediately print their application so I'd like to still give them the option to immediately print but also send them an e-mail with a link to their specific row in the MySQL db. I have an autoincrement field as the primary key for each table, but I think sending this key to the applicant in an e-mail would be too easy for them to guess another id and access other people's info.
    I'm thinking I should add a column to each table which would contain a unique random number and I would then send this key in the e-mail to the applicant. So, can anyone suggest a simple way to do this or suggest a better way of giving the applicant a way to access their own application and no-one elses after they have submitted their form?
    Thanks all.

    Thanks so much, that was very helpful. I added the code you suggested to create and display the random number - I called it "vollink" and that worked fine. Then I added the hidden field toward the bottom of the form - it shows at line 311 when I do a "View Source in Int Explorer and then tried adding the code to add it to the table and when I tested it failed with "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1" . The test version of the page is here www.hollisterairshow.com/volunteerapp2.php . The changes I made to add it to the table is shown below , I must be missing something blindingly obvious, if you could suggest a fix I'd really appreciate it. I did add the field to the MySQL table also.
    Thanks again

  • How to fill array with random number?

    I need to fill a 3-dimensional array that has user-controlled dimension sizes with random numbers (1-10). I'm unsure of how to do this. I feel like I have to use the initialize array and maybe the build array functions somehow but I'm not entirely sure. Any help would be appreciated. Thanks.

  • Generate a random number and make it STAY after "save"

    I searched around this forum and found that I can use this code to generate a random number:
    //this.rawValue = Math.round(Math.random() * 1000000);
    Works great. only problem is, once I practice on the "real" form and save, close, and reopen - it changes the random number every time. I need to figure out a way to make it save the 1st number it generates when someone opens the form and types info in it....then they save and close, etc.
    Can anyone help me? Thanks!!

    Example steps:
    1. Add a hidden field to the same subform with name 'hiddenField'.
    2. First time you open 'hiddenField' rawValue will be null.
    3. where ever you run the code to generate random number use scenario like this.
    if (hiddenField.isNull) {
    this.rawValue = Math.round(Math.random() * 1000000);
    }else {
    this.rawValue = hiddenField.rawValue;
    Hope this thelps.
