Syntax Description

---

number Any valid numeric expression

Details:

Rnd returns a single-precision value that is between 0 and 1.

This function returns the next random number in the sequence started from the initial seed value.. Each successive call to Rnd uses the previous random number as a seed for the next number in the random-number sequence. The value of number determines how Rnd returns a random number as shown in the following table:

---

To return... Enter a number...

---

The same number every time, as determined by number. < 0

The next random number in the sequence. > 0

The random number that was generated most recently. = 0

The next random number in the sequence. number omitted

Use the Randomize statement without an argument before calling Rnd to generate a different random-number sequence each time the program is run.

To generate a specific range of random integers, use the following equation where upperbound is the maximum of the range, and lowerbound is the minimum:

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