# Excel RAND Function

The Excel RAND function returns a random number between 0 and 1. For example, =RAND() will generate a number like 0.422245717. RAND recalculates when a worksheet is opened or changed.

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.

### Examples

RAND takes no arguments:

### Automatic recalculation

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:

RAND()*(b-a)+a

For example, to generate a random number between 1 and 9:

RAND()*(9-1)+1

The RANDBETWEEN function can generate random integers between to numbers:

=RANDBETWEEN(1,9) // random number between 1-9

*Note: In Excel 365, the RANDARRAY function is another way to generate multiple random numbers, and to generate random numbers between two values.*

### Notes

- The RAND function takes no arguments.
- RAND recalculates whenever a worksheet is opened or changed.
