Int((upperbound - lowerbound + 1) * Rnd + lowerbound)

Here, upperbound is the upper limit of this range, and lowerbound is the lower limit of this range.

Note:To repeat the random number sequence, call Rnd with a negative value parameter immediately before using the numeric parameter. Using the same number for Randomize cannot repeat the previous random number sequence.

Optional. A valid numeric expression.

If the number is:

  • <0 - Rnd returns the same value each time.
  • >0 - Rnd returns the next number in the sequence.
  • =0 - Rnd returns the last generated number.
  • Omitted - Rnd returns the next number in the sequence.
