How to generate random numbers that doesnt contain characters?

How do we generate random numbers in ESB ROuting Service/ XSL transformation that does not contain characters. I have been using "orcl:generate-guid()" , but it contains some characters, so, I substring it to get only numbers. I dont want to take this risk and in future, my substring itself may contain characters.
Has anybdy tried this before?
Thanks,

If the goal is to have a pseudo random number then consider using the translate function to replace the occurances of the A - E characters with another digit. For example:
translate(orcl:generate-guid(),'0123456789ABCDEF','0123456789123456')
This will produce a 1 for A, 2 for B, etc. While not a valid hex to decimal conversion of the GUID value, it does get around the hex issue and might be sufficient for your purposes.
I would perform a large sample test to see just how unique the values end up being.
As for why hex is used, well GUID's are most commonly written in text as a sequence of hexadecimal digits such as: 3F2504E0-4F89-11D3-9A0C-0305E82C3301. i.e. 128 bits represented in 32 characters formatted into 5 sections.
Hope this helps,
Peter

How to generate random numbers in a range using random class?

I know how to use Math.random for this, but how would I generate random numbers using the random class?
Say I want a number between 40 and 50, inclusive--how would I do this?
What i have in mind is:
int randomNumber = random.nextInt(max) + min;
where max is 50 and min is 40. Is this correct?

How to generate random numbers with a known distribution of f(X)=(8X^2 + 1)*Exp( -X^2 )

Dear All,
I need to simulate a random number generator which can generate numbers X with the probability distribution of
f (X) = ( 8X^2 + 1)*Exp ( -X^2 ).
This distribution is not a common distribution.
I have searched a lot, but I still do not know how to realize it.
Any help on this topic would be highly appreciated.

Make a lookup table of the integral of your function (normalized to 1)
Use the rectangle random generator and pipe that value through the lookup table, scale it ... voila.

How to generate random numbers in a range?

Hello. i am having trouble finding out how to generate a random number in a certain range. For example i have an array of 100 elements and i want to access one of the elements between 50 and 60, however i cannot find how to generate a random number between these two values.
Thanks in advance

java.util.Random.nextInt(int)
Note that you can get a number between 0 and (max -
min), exclusive. Then add min, and you've got your
number.Obviously you didn't read this. It says to get a number between 0 and (max - min) which is actually what you did. But after that you need to add min. The first step would get a number in between 0 and 5. When you add 20 you'd get a number between 0+20=20 and 5+20=25.

Do not randomize the random number interface when you start your application. When the random number interface is not randomized when starting you get the same sequence of numbers each and every time you use it.

Don't forget to index back into the original X array for correctly scaled data. Here's a simple example (LV 8.0):

so if i wan generate btw A to Z am i suppose to type A to Z out?
Edited by: marufai on Sep 24, 2007 12:32 PMI like uj's method since it's more extensible, even though it's a little more work up front.
If you have a range, say A to Z, then loop over the characters in that range, adding them to the list.
        List<Character> list = new ArrayList<Character>();
        for (char index = 'A'; index <= 'Z'; index++) {
            list.add(index);
        }Do that for all of the ranges that you want to add to the possibilities, and then choose random numbers between 0 and the length of the list.

How do I generate an array of random numbers that relate to an output wave that falls within a certain frequency range?

I have been creating random numbers that I'm using within a system, the system is working fine, but now I have realised that the random numbers must be outputted to speakers in such a way as to filter out all but a low frequency range.
I was thinking about generating a dither signal with a bandpass filter, but could not get it to give me out a full array of 250 values which I could then manipulate.
The sampling frequency of the output is 200Hz and the 250 data points must fall within the 0-100Hz range.
Another course of action I am considering is to use an FFT and an inverse FFT to get the data that I'm looking for, but I'm fair
ly inexperienced with using labVIEW and can't quite get it to work.
Thanks for the help,
Hank.

As you may already know, in the Functions palette/Analysis VIs/Filters VIs are VIs for filtering. There are also some examples for using these filters under Examples/Analysis/fltrxmpl. You may find some of these are related to your situation, especially for filtering out the higher values.
An option is to simply output the random values to a Comparison/"less than or equal" function, where only values <= to 100 would be sent to an array which is in a For loop. Use the iteration counter of the For loop to count up to 250, at which time you would pass the whole array to your next node. This would let you have 250 values between 0 and 100 for your final array.
Good luck.

Need An Algorithm That Generates Random Numbers

Hi, I understand that there is a built-in random number generator. But, I need an algorithm that generator random numbers. Is there one available? Thanks.

Hi, is the "Seminumerical Algorithms" a book?What
the numbers 3141592621 and 907633385 stand for?The first is PI without a decimal... the second I
don't know, it may as well be randomly picked.As far as I know the numbers aren't randomly picked. You want the distribution to be good, and the length of the serie should also be long. Some numbers causes the cycle to be short, or the distribution to be bad. I think there are articles that lists 'good' numbers.

How to generate random sequence numbers

Hello experts
Iu2019m writing a custom program and pulling data from VBAK & VBAP. As per requirement I also need to generate a sequence number randomly and finally store all data in text file and upload at server. The hiccup is I donu2019t know how to generate sequence numbers. Can somebody please show me how I can accomplish it?
Thanks a lot in advance

Find the below code,
data: lv_range type datatype-char0128.
call function 'RANDOM_C'
    exporting
      len_min   = 20
      len_max   = 20
      char_min = 1
      char_max = 20
    importing
      rnd_value = lv_range.
LV_RANGE param will have a random value..
If you need number you can use the FM "RANDOM_I4"
Thanks,

How To generate random activation code

Hi Guys
It might be a very simple question for most of you. I've seen many websites when you register, they send you an email with an activation code.
It kind of looks like : XA432G2DGR343
How do we generate something like this in Java. I know we can generate random numbers? Any tips on how to go about it.
Thanks

How do we generate something like this in Java. So let me see if I have this straight. You are asking us to help you create a program, one that allows you randomly generate activation codes, and with these codes you will try to crack into websites where you haven't registered for or where you possibly haven't paid some entrance fee? Is this correct or am I missing some basic element of logic here? If I'm wrong, please correct my mistake. If I'm right, then you can go to hell.

Anyone know how to generate random midi in real time? part 2

anyone know how to generate random midi in real time?
http://discussions.apple.com/thread.jspa?messageID=11342321
This article was archive so I can't reply to this, but I wanted to bring this back up.
As Christian pointed out on converting your notes to P-Press, then random DataByte 1 then convert back to a Note...
I used this approached but was able to add in a macro I created to save the generated random DataByte 1 so that when the Note OFF message came around, I can apply that saved random DataByte 1 to the Note OFF in question.
One thing I did notice when working this out was there's 2 differences in processing the messages when it comes to using a MIDI Input Device or a MIDI Performance (midi file).
After I was able to figure this out, now I can randomize on notes using either of the 2 Inputs.
While randomize notes probably won't sound nice to the ear, I apply another macro I created and I'm still adding too, and that's Music Scales.
So while I randomize notes, when applied to this last macro, the random notes now get mapped to notes in a music scale of your choosing.
This link shows what I did.
http://www.digimixstudios.net/RandomizeNotesUseScales/
I'm currently in the process of creating video tutorials in breaking down the whole process but I wanted to share what I have and see if there's any interested in this.
Remember, this is just one approach and I hope it gives others ideas to work off of.
