Excel Rand Function

Related Function:
RANDBETWEEN

Basic Description

The Excel Rand function generates a random real number between 0 and 1.

The function takes no arguments and therefore, its syntax is :

RAND( )

Although the number generated is between 0 and 1, you can use the function to generate a random real number between any two supplied limits a and b, using the formula:

RAND( ) * (b - a) + a

Rand Function Examples

The spreadsheet below shows three examples, in which the Excel Rand function is used to genrate random numbers between different limits.

  A
1 =RAND( )  - returns a random real number between 0 and 1
2 =RAND( ) * 100  - returns a random number between 0 and 100
3 =RAND( ) * 10 + 10  - returns a random number between 10 and 20

Note that the above formulas will return a different random number every time the spreadsheet recalculates. To force a recalculation at any time, press the F9 key.

Further information on the Excel Rand Function is provided on the Microsoft Office website.
