Problems with random numbers

I want to create a variable, xSpeed, which has an equal chance to be 10-10 or 0. Here's what I have so far:

xRandom = random (3);
If (xRandom < = 1) {}
xSpeed = 10;
} ElseIf (xRandom < = 2) {}
xSpeed = - 10;
} else {}
xSpeed = 0;
}


So, there should be an equal chance to put xSpeed as 10, -10, or 0 to right? Instead I think it's always 10 or - 10.

If I change to xRandom = random (3); for xRandom = random (4); then each value has an equal chance to be implemented. But this should be the case for the random (3) surely?!

Also, if I change to xRandom = random (3); for xRandom = Math.random (3); then xSpeed always seems to end up like 10. What is with that? What difference does add math do?

I must be missing something important about the functioning of random() because it isn't making any sense to me: (.)

Perfect. Thank you very much

  • I have a problem with the numbers. Help, please!

    I have a problem with the numbers. I am trying to create a formula that can add a cell only when another cell with a pop-up menu returns on a specific pop.  I can't ignore the cell if it is not on specific pop upward.

    assuming the cell with pop's cell A1

    and if the context menu contains items:

    YES

    NO.

    MAYBE

    and the value you want to add in cell A2

    You can add the value in cell A2 when the context menu is 'YES' like this

    = if(A1="YES", A2, "") +.

    where is the expression that adds other cells if you want

    could be another cell

    = If (A1 = "YES", A2, "") + B2

    or a range of cells

    = If (A1 = "YES", A2, "") + sum (B2, D2, G2:H5)

    The amdxhc.sys is dated January 3, 2012 and the usbfilter.sys is dated November 16, 2011.

    Two of these drivers should be updated to the latest version to ensure compatibility with the motherboard and between them.

    HP has an available Update for AMD USB 3.0 driver but I do not see an AMD USB filter driver available for your computer updated.

    I might suggest to try to get the package of motherboard chipset from AMD for versions newer and compatible to the two pilots.

    You can try the "AMD Chipset drivers' starting from the following link which should update the two drivers.

  • Another problem of random numbers

    I say 'Other' because there is an existing thread of random numbers on the first page of this forum, but it is unresponsive to my problem.

    I'm generates names for an array of objects. I have an array of words (strings) to the choice. I use Math.random () * 151 to select indices array of two words. I want to check that the two chosen integers are not the same before assigning the name to the object. Then, I want to check to make sure that none of the two objects have the same name. Simple, right? Here is the code:
        for(int i=0;i<numStars;i++){
            ok=true;
            do{
            int part1=(int)(Math.random()*151);//first index
            int part2=(int)(Math.random()*151);//second index
            if (part1==part2){//make sure they're not the same number
                ok=false;
                System.out.println(part1+" "+part2);
            }else{
                stars.name=new String(starName[part1]+" "+starName[part2]);
    for(int j=0;j<i;j++){
    if(stars[i].name.equals(stars[j].name)) {//make sure no two stars have the same name
    ok=false;
    System.out.println(stars[i].name+" "+stars[j].name);
    }
    }
    }
    }while( ok==false);
    )//end of for loop


    The problem is, if integers part1 and part2 are equal in one pass through the do loop, they remain identical in each subsequent pass. The number doesn't stay the same, but whatever part1 is, part2 is always the same thing. This is only true after matching up one time. It's possible for it to run without ever hitting a duplicate.

    I changed it to ensure that part1 and part2 weren't covering the same range of numbers, and the same error started happening in the lower for loop that compares one object's name to another. This second-level error doesn't occur when part1 and part2 both cover the full range.

    I don't think it's possible with the code you have posted.

    What will happen, however, given that you set never ok = true once part1 and part2 become unequal, is if they are equal in the first pass through the do / while loop, you will never get out of this loop.

    It is also unnecessary and bad form to use == or! = with the value true or false

    // bad
    x == true
    x != false
    
    // good
    x
    
    // bad
    x != true
    x == false

  • Problem with the numbers in the rows of cut and paste

    Hey,.

    I'm new to MAC and now have problems with the help of figures, I brought my windows Excel worksheets. On windows, I could cut a line and paste anywhere on this page and by practice that Excel would fill the void rank where I cut the content. but here on MAC it does not work, why?

    anyway I tried to live with it by cutting a line and for the collage, I used Insert > copied lines for paste swath and add a line for her. but last night I updated the numbers and now by the practice precedes the Windrow is stuck this time with a resized form, the line is resized to a big line.

    Why is this happening? If it can't be fixed, I can go back to a previous version of a number? This update of hate.

    Numbers is excellent NO then you should consider to guide your expectations.

    Cut number refers only to the content NOT the line, or cells.  Select when a row, and then use the cut command that you cut the contents of the cells.

    If you try to move a line from one place to another, you should try this method (which can work for you)...

    Select the line, then click and hold on the header line (up to the line "lift" on the table), the operation slide the line to the destination.

    Now drag the line:

  • Calculation of tabular form, problem with decimal numbers

    Hello

    I wrote a simple java script function that is responsible for calculating the price * quantity and store that value to total_price.

    Hi John,.

    before the multiplication, you analyze your values as an integer, so 'cut' the decimals.
    Replace "parseInt" by "parseFloat" should do the trick.

    function CalcTotalPrice(pThis)
    {
    var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
    html_GetElement('f07_'+vRow).value = parseFloat(html_GetElement('f06_'+vRow).value, 10) * parseFloat(html_GetElement('f05_'+vRow).value, 10);
    }
    

    Please let me know if this worked for you.

  • Problem with creating numbered lists the paragraph style...

    I have a numbered list, using "bullets and numbers" paragraph style But I don't know how to get the numbering to work properly.

    If I set the "mode" to "continue from previous" mode, whenever I use this paragraph style continuous numbering since the last issue of the previous list using this style.

    If I put the 'mode' for ' start in ' a number, say '1', then all numbers in the list are this number.

    I want that each list is independent of the final list. The only thing I can understand is to create a new paragraph for each list style, but which does not seem a good way to go.

    I have been exploring for some time but have not been able to understand this.

    Place the cursor inside your paragraph of the list where you want than to restart numbering.

    Choose from the menu:

    Type > bulleted & numbered lists > restart page numbering.

  • How the random numbers will be generated

    The "dice" in LabVIEW function is ised to generate random numbers between 0 and 1. If I create a [100000] array with random numbers between 0 and 100, the appearance of 1 to 100 is the same (about 1000 times each), but the appearance of the 0 is only 500.

    So my question is, on the basis of which will be generated random numbers?

    Mitu salvation,

    It is not a problem of the RNG, it's a problem of your function rounded!

    "To U8" allows you to convert the entire random DBL. ToU8 rounds up to the next integer. So all the number of 0-0.5 will get rounded to 0, but all the numbers from 0.5 to 1.5 will get rounded to 1. If you have twice the range of a number rounded to 1 at the beach of rounding to zero - the same goes for your "end of range" with rounding to 100. 100 should be also less likelihood (in your VI) to appear...

    To get the same probability, you should (explicitly) roundpupils before converting in U8!

    BTW. You can also search the forum to get the same answer by searching for "random"...

  • Problem with tables

    Hi all!

    I was doing a simple practic, it is a random 3D Board and the problem is that I can't properly use the index in real time with random numbers.

    Here you have two VI, the first is simple, it is a 3D picture, but if you want, you can change the rows or columns and you will see the element changing to the same table 3D.

    But in the second is the problem, here's another 3D painting, but it is filled with random numbers, and when filling it finished start more and, instead, I see all the loose of the original 3D array.

    How could I do that the picture of random origin remains until I want to generate the following, and before that I then generates the one that I can get all the digital changig loose control (pages, rows and coulmns)?

    Your VI is run once and then stop. If you want to update you choose index different values then you must encapsulate this part in a while loop with a stop condition.

    When you want to generate a different set of random numbers click the stop button, and then rerun the VI.

    I suggest you only start by reading some tutorials online on LabVIEW programming. They should teach you the basics.

  • HP ENVY notebook - m7-n011dx: problem with keyboard

    The situation began early September, I noticed something was wrong. Whenever I tried to use one of the symbols by pressing SHIFT and the number, it does not meet my contact. Evenutally 30 seconds to a minute, after pressing the button several times and pressing him hard, he evenutally works.

    During this time, I'm just having the problem with the numbers of typing on the letter keys. Even by pressing the SHIFT key, both of them, would be about a minute for three minutes. As we speak now, I'm having a problem just get the numbers to type.

    I fear that it is perhaps a material thing, because my missed warranty back to the month of August and the money is a problem for me at the moment. For the fact that it is a problem to connect to my computer or by using password with numbers and even trials of typiing, I found this irratiable to do any work. I was thinking of doing a new keyboard, but I still don't like the fact this computer is just a year old, but I'll have to buy a keyboard for this. I want to say that it can only be a softare related question because if it was the key, I think the backlight would be as well, but I think it's a keyboard related question, a related software or I'm not cleaning the keyboard properly. Can I apply for aid because it frightens me that several issues came into play.  Other than the keyboard related question, it's the only thing that is wrong with this computer. I'm ashamed that I'm a major TI and I don't know what may be the issue.

    Hi@SoZo-TEKI,

    Thank you for the answer.

    Try the following steps to change the region of the keyboard settings and check to see if that solves the problem.

    • Click on the Start Menu. ...
    • Click settings.
    • Click time and language.
    • Click on the region & language.
    • Click the language that you want to add a keyboard layout to.
    • Click on Options.
    • Click on add a keyboard.
    • Click on the keyboard you want to add. (Ideally, it should be (English - U.S.).

    It will be useful.

  • problem with the data record

    Hi, I'm new to LabView so I know that the thing I'm doing is relatively easy, however, I'm stuck.

    I made a small program that gets 5 steps (for now replaced with random numbers) and as well as the date and time data in the text file. I intend to run the program for long periods of time, so I want to increment the file name/path every hour, but after the addition of this part of the program does not create any file, although the program runs without error.

    Block diagram is attached, could someone point out to me what is wrong and what I should do to reach my goal?

    Thanks in advance!

    Hi marcis,.

    Acually, the logic of the program was completely wrong.

    1. your comments the file path will never help you. Because after leaving of while loop, the structure of matter will run once and LV will stops running.

    2. open and close the datalog only once file. Try to make all your manipulations between opening and closing your file datalog. Otherwise, it will be difficult to manage when you develop your code.

    3 case construction outside the loop is meaning less. If you want to run the program permanently, place all functions inside the while loop you want to run. While the loop will run continuously until you get satisfied.

    4. incorrect data streams. All programmers need well with the data stream.

    Just go into the basics of labview here and try to realize your logic again

  • Problems with AE CC15 tasks performed on a Render Farm

    Hello

    We use Thinkbox date limit to submit work to our 30 node makes firm and have problems with random nodes (nodes each time) never solve their tasks. We must then manually stop the task and submit again to make it start happening. Sometimes it hang on 0% for several minutes but suddenly to 100 percent and show the work as complete. However, when we check the folder, there are several missing frames. I spent a whole day with Thinkbox support on this issue and they have come to the conclusion that it is a matter outside the deadline; then told me that I would like to contact Adobe support. I have several screenshots, of employment and newspapers of the slave, as well as the thread of emails and messages from command line with strange of Thinkbox for reference results if these will help.

    I saw this problem too.   I found that this does not happen if I keep the deadline for a task by machine.  But who does not profit from our hearts very well.  I also found that the nodes have tried automatic backup of the AE file at the same time, causing conflicts.  I ended up going in each launch of AE node and disable the AutoSave every minute 20 and "save when the queue starts.   I also disabled the preference of cache disk rendering nodes because I think it does a thorough check of all resources related to the AE file which was very demanding on our network and NAS all nodes of marketing.  I think that some nodes are time and only covers do not update the cache and I did not want to used the cached data anyway.
