If decimal numbers are used as input values, the LOW value will be rounded up for the lower boundary and the HIGH value will be rounded down for the upper boundary. If this method is wrong then please guide me I will also stop trying this. If you change from RANDBETWEEN(1,100) to your other suggestion of RANDBETWEEN(1,50), the probability of no duplicates drops from 62.82% to 38.17%, and the expected number of columns with duplicates increases to about 158 of the 256 (and typical values seen are between 143 and 173).

Created on August 5, 2011 =Randbetween results with no duplicate numbers. We can use the RANDBETWEEN function to create random numbers between a certain range, say 1 and 100, but there is nothing in the function to prevent duplicate numbers from being created in the range. But since lT(x) is zero, it will be interpreted as uninitialized. If I may join the discussion thread. Heres the screenshot: Now, about the number. If you delete and again insert the RAND formula, this time you will get a new random number. Either email addresses are anonymous for this group or you need the view member email addresses permission to view the original message.

As mentioned above repeat the same steps like pasting it upto A10 cell and do copy and paste it as values and apply countif formula to check for duplicates. For example, this RANDBETWEEN formula generates a random number between 1 and 10: =RANDBETWEEN (1,10) The function will generate a new random number each time your Sheet changes.

You can't (to my knowledge) merge this into one formula, because randomizing functions are triggered by each sub-formula within a longer formula, so you'd wind up with duplicates. How do you assign the number in [Starting Position] column with the subscription? I don't think the "late initialization" algorithm works correctly when the lMin-to-lMax range includes zero. See JE McGimpsey's site for a solution to this problem. 1. Now assume the second random position is the same lT(x) coincidentally. > If you agree, I think the simplest solution is to disable the "late> initialization" algorithm when the lMin-to-Lmax range includes zero. You can easily get a unique integer between 0 to 100, where 100 is not inclusive, with the following RAND and TRUNC function combination. Switch back to the first sheet. They all return #VALUE instead of the intended error. =byrow(ArrayFormula(if(A2:E>=F2:F,A2:E,)),lambda(r,count(r))) It compares A2:E against F2:F and returns the count. ), Making Google Sheets look less like Google Sheets, BYCOL Function in Google Sheets LAMBDA Helper Function (New For 2022!

RANDARRAY can generate random decimal numbers and random integers, and can also . We can overcome this by deducting our desired lower value from the output. They all return #VALUE instead of the intended error. By creating a single helper column with RAND(), we can refer to it with the other formula while not getting duplicates. Displaying random cells from a list, without duplicates? But you can of course specify individual sheets in a workbook one by one.

"Ms-Exl-Learner" wrote in message news:C0CFE96D-5D4F-4439@microsoft.com Before that I used to increase the randbetween maximum value depends upon the number of cells for which I am going to apply. Try this macro, Set your maximum number to whatever you want but it must be larger than the number of cells in the fill range. RAND Function in Google Sheets You can directly use RAND function in any cell to generate a random number as, unlike RANDBETWEEN, it doesn't take any arguments.

This way you can prevent duplicates in Google Sheets. in your example it's 1) and a maximum range ( i.e. Note: Both RAND and RANDBETWEEN are considered volatile functions, meaning they don't retain the data in the cell forever.

The RANDBETWEEN Function in Google Sheets allows you to generate random numbers between two specified values. The syntax for this function is: =RANDBETWEEN ( [lower_limit], [upper_limit]) In the above formula, you can specify the lower and the upper limit. In RAND function also you can apply low and high-value arguments indirectly. Only replace the earlier formula with this new one. Finally, the INDEX function returns the item from column A at the position denoted by the random number: Combine the RANDBETWEEN function and the CHOOSE function to pick random items from a list: The values can also be referenced in cells, as in this example: Feel free to make a copy: File > Make a copy.
