The RAND function returns a random decimal number between 0 and 1. For example, =RAND() will generate a number like 0.422245717. The RAND function takes no arguments. RAND recalculates when a worksheet is opened or changed.
RAND takes no arguments:
=RAND()// returns number like 0.073979356=RAND()// returns number like 0.080313118
The RAND function will calculate a new result each time a worksheet is edited. To stop random numbers from being updated, copy the cells that contain RAND to the clipboard, then use Paste Special > Values to convert to a static result.
To get a single random number that doesn't change when the worksheet is calculated, enter =RAND() in the formulas bar and then press F9 to convert the formula into its result.
Multiple random numbers
To generate a set of random numbers in multiple cells, select the cells, enter =RAND() and press control + enter.
Random number between
To generate a random number between a and b, you can use a formula like this:
The RAND function generates a decimal number between zero and 1. So, you might get output like this from RAND() in three cells:
Dates in Excel are defined as simple numbers, where...
This formula relies on the helper table visible in the range B4:D10. Column B contains the six numbers we want as a final result. Column C contains the probability weight assigned to each number, entered as a...
At the core of this solution is the RAND function, which is used to generate a random number in a helper column (column C in the example).
To assign a full set of random values in one step, select the range C5:C16,...
The Excel RANDARRAY function generates an array of random numbers between. The size or the array is is specified by rows and columns arguments. Generated values can be either decimals or whole numbers.
