Re: Generating a random number between 1-10;
How do I generate a number between 1-20? I saw how to on this forum once, but I can't find it, and I don't have much time to look. Sorry for any inconvinience. What I want to do is assign to the variable x the random number.
Thanks.
Virum
Random rnd = new Random();
int x = rnd.nextInt(20)+1;

Build a VI that generates a random number between 1 and 80
Divides the random number by a number specified in the front panel.
If the inputted number is zero, the VI program should turn on a LED in the front-panel to indicate a divide by zero error.
Solved!

How can you generate a random number?
Say I have a timer, and I need it to choose a random number between 100 and 1000. How would I do that?
timer.delay(***RANDOM***);Thanks!I have this, and it's working for me:
int j = rand.nextInt(500);
But I actually want it to generate a random number between 100 and 500, not 0 and 500. How could I do this?

Random Number between 10 and 30
I'm just curious how to generate a random number between 10 and 30. I know I use the Math.Random function, but I'm not certain how to do it when the starting number is >1 (i.e. 1 to 30). Thanks.
Random Number in an Interval:
((int) (randomGeneratedNumber * difference)) + startIndex + 1
* randomGeneratedNumber - Number >= 0 and <1
* difference: To generate between 10 and 30, (30 -10 = 20)
* startIndex: In this example, 10
* +1: Neccesary adjustment.
Example:
((int)(randomGeneratedNumber * 20)) + 10 + 1
PD. Int cast it's to generate int numbers, so it's optional. -
Get a random number between 2 numbers?
Are their any classes which can produce a random number within a set of numbers i specify?
If their are no predefined java classes then it doesnt matter.
ThanksNo as far as I know, but its easy to create one:
double low_Limit, super_Limit;
double interval = super_Limit - low_Limit;
//Generate a random number between 0 and 1, with a Java satandard class
double random_number = Math.random();
//Now we generate a random numbre between 0 and intervalo:
random_number = random_number * intervalo;
// now we generate a random number between low_Limit super_Limit:
random_number = random_number + low_Limit;
//done :)

How to generate n random dates between 2 time periods
Hi,
I'm trying to write a method that generates n random dates between 2
time periods. For example, lets say I want to generate n random dates
between Jan 1 2003 and Jan 15 2003. I'm not sure how to go about
doing the random date generation. Can someone provide some direction
on how to do this?
The method signature should look like this.
public String[] generateRandomDates(String date1,String date2,int n){
// date1 and date2 come in the format of mmddyyyyhh24miss.
// n is the number of random dates to generate.
return dateArray;
Thanks.
Peterfirst take a look at the API concerning a source of randomness (Random might be a good guess), then take a look at stuff concerning dates (Date might be cool, maybe you will find some links from there).

How do you generate a random number?
You can also check out Math.random() which returns a
double value between [0..1)You could, depending on your needs, but if you do want ints then you're better off using nextInt from java.util.Random, as outlined by the author here:
http://java.sun.com/docs/books/effective/excursion-random.html
(and what was wrong with 125?! I thought that was a perfectly fine random number...) -
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.

How to generate a random number with at least 6 digits?
Hi all,
All is in the question. :-)
I would like to generate a random number but the function "random
number" in Labview isn't accurate enough.
Do you know an algorithm to generate a random number of 6 or more
digit?
Thanks,
PFHi PF,
It's simple. Use 2 random number functions in the same process. Now you
should have 2 distinct random numbers that have the same accuracy. Let's say
LV gives accuracy up to the thousandth (0.XXX), now if you divide one number
by 1000 and then add to the other number you should then have something like
0.XXXXXX. Actually, LV random number function can give up to about 17 digits
(decimal). If you are looking for more digits (>17 digits), the idea above
may not work, then the last thing you may want try is to generate two or
three random numbers then convert all these decimal numbers to fractional
strings chop off the 0 and dot then concatinate them together. After all
it's still a random number. How many digits do you want to get? Make sure
the indicators acce
pt that many digits?
Good luck
Louis.

Random number between 1 & 16?
Hello all. I need to create a variable that holds a random number between 1 & 16. Any idea how I can do this? This is the way the variable looks right now:
var randomTurkey:Number = Math.floor(Math.random()*100);Never mind, I got it. Thanks!

How I get random number between 1 and int number ?
how can I get random number between 1 and int number
like between 1 and 10 etc.
10xUse the nextFloat() method of the Random class, this returns a random number between 0.0 and 1.0. To get and integer range from that multiply the return value of that method call by the integer range you need (in this case 10), and add the starting number you want returned in the range (1 in this case). The code below works for numbers 1-10.
Random r = new Random();
int x = (int)(r.nextFloat()*10) +1; -
hi all!
how can i find random number between an specified range
for example b/w 5-10
thanks to all
smhHere's a practical instance;-import java.util.Random; // Maybe you forgot this
public class ImplementRandom {
public void getRandom(int from, int range) {
int newRandom;
Random random = new Random();
newRandom = from + random.nextInt(range);
System.out.print(newRandom);
public static void main(String[] args) {
ImplementRandom IC = new ImplementRandom();
IC.getRandom(1, 100);
}Actually that uses public void rather than public int as you cannot reference a non-static (return-type) method from a static context. -
How to generate a random number within a specified tolerance and control that tolerance.
I am trying to simulate data without using a DAQ device by using a random number generator and I want to be able to control the "range" of the random number generated though. On the front pannel, the user would be able to input a nominal number, and the random number generator would generate numbers within plus or minus .003 of that nominal number. The data would then be plotted on a graph. Anyone know how to do this? Or if it's even possible?
Just for information sake, the random number is supposed to look like thickness measurements, that's why I want to simulate plus and minus .003 because the data could be thinner or thicker than the nominal.
Thanks in advance!!
Solved!
Go to Solution.You can create a random number with a gaussian probability profile using two equal distributed (0...1) random numbers and applying the Box Muller transform.
I wrote one many years ago, her it is. (LabVIEW 8.0).
