RAND( )

Remarks

  • To generate a random real number between a and b, use:

RAND()*(b-a)+a

  • If you want to use RAND to generate a random number but don't want the numbers to change every time the cell is calculated, you can enter =RAND() in the formula bar, and then press F9 to change the formula to a random number.
