Generate a pseudorandom number, a value between 0 and 1 (less than 1 but greater than or equal to zero.)
Syntax Rnd[(number)] Key number This argument is a Single or any valid numeric expression, it determines how Rnd will generates a random number:
|If number is||Rnd generates|
|Less than zero||The same number every time, using number as the seed.|
|Greater than zero||The next random number in the sequence.|
|Equal to zero||The most recently generated number.|
|Not supplied||The next random number in the sequence.|
For any given initial seed, the same number sequence is generated because each successive call to the Rnd() function uses the previous number as a seed for the next number in the sequence.
Before calling Rnd, use the Randomize statement to initialize the random-number generator with a seed based on the system timer.
To produce random integers in a given range, use this formula:
Int((upperbound - lowerbound + 1) * Rnd + lowerbound)
The Rnd() function can be used in VBA or in an SQL query.
Dim intDemo as Integer
'A random number between 1 and 6
intDemo = Int ((6 - 1 + 1) * Rnd + 1)
'A random number between 1 and 100
intDemo = Int ((100 - 1 + 1) * Rnd + 1)
'A random number between 50 and 100
intDemo = Int ((100 - 50 + 1) * Rnd + 50)
