Random Number

Dec 10, 2006

How do I make a row of 5 random numbers in A2:A6 that are not the same as each other. It's basically for a Bingo card. I have a formula that can calculate the random numbers =INT(RAND()*15)+1 under the B's for example, but I can't seem to figure out how to make it so they are not the same.

Random Number Between Two Numbers VBA

Jan 3, 2014

I have build a system that needs a lot of random numbers generated to work.

I have used what I thought would work to generate me these numbers like this example:

VB:
Lastrow = ThisWorkbook.Sheets("RPlay").Range("A" & Rows.Count).End(xlUp).Row
RPlayerNum = Int((Lastrow - 2 + 1) * Rnd + 2)

This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.

However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.

MC W/Random Number Generation

May 4, 2006

I get the following error whenever I try running a Monte Carlo simulation with iterations in excess of 64000 (The MC simulation calls the 'NormSInv' worksheet function at least once per iteration, and the argument to the 'NormSInv' function is always a standard normal RANDOM number also generated by Excel VBA): Run-time error '1004': Unable to get the NormSInv property of the WorksheetFunction class
Why do I inevitably encounter this error ONLY when the number of iterations exceeds 64000, for instance? Simulations with iterations < 64000 run smoothly without a glitch.

Generate Random Number Between

Nov 28, 2006

i have worked in access using vba procedures. i can easily create a form in access that generates a random integer number between 0 and 20 and the user will guess the number between 1 to 20 if the random number is 16 and the user enters 14 the program will display a msg box saying too low or too high. here is the code .

Option Explicit
Private Const MAX = 20
Private Const MIN = 1
Private iKey As Integer
Private lTries As Long

Private Function Random() As Integer
Random = CInt(Int((MAX - MIN + 1) * Rnd() + MIN))
End Function

Private Sub cmdGuess_Click()
Dim lGuess As Long

now i have to do the same thing in excel create a program that will ask the user to enter numbers between 0 to 20 and see if the random number and user guess is same or not. but i have never worked in excel using vba procedures how can i achieve the same thing in excel using a vba procedures.

Advanced Random Number Generation

Jul 29, 2009

I understand how RAND and RANDBETWEEN work, but have a slightly more complicated random number generation problem that requires a number that isn't solely between two numbers.

I have one cell that is randomly generating a number between 0 and 350 (we'll call this value A) and another randomly generating a number between 0 and 15 (value B). Then, I have a third cell (value C) that equals 15 minus B. Where I am having trouble is with a fourth cell (value D). This cell I want to have randomly generate a number between 0 and 350 but it needs to be D less than the value in A or C more than the value in A. Is there an advanced random number generation technique that can solve this?

Generating Random Number List

Oct 20, 2009

I have a spreadsheet of 1000+ companies and I want to take a random sampling of 100 of them. I would assume this could be accomplished by auto-filling a numerical value to each line of data (which I did), then scrambling only the column with the numbers (which I can't figure out), and then selecting the entire text and resorting it to put the numbers back in order and then just work with the first 100 rows (which I can do, if I knew how to make the numbers random).

Random Number Generator From 1 To 7 Other Than Cell Value

May 12, 2007

I have a range of cells that have values from 1 to 7 in them. What I would like to do is to have the next column generate a random number from 1 to 7 that does not generate the number that the cell next to it has. for example if cell A1 has 6 in it, I would like cell b1 to generate a random number other than 6 in it. if cell A2 has 3 in it then cell B2 would generate a number other that 3 (1,2,4,5,6, and 7).
