Remarks

RAND()

The RAND() function will generate another pseudorandom number each time it is evaluated. It returns a fractional number on a unit basis, therefore you can use RAND() to produce numbers between 0 and C by multiplying the RAND() result by C. It follows that to produce a pseudorandom number between A and B you could translate the result by A like this:

RAND() * ( [B] - [A] ) + [A]

The number generation of the RAND() function derives from the system clock, and therefore may not be entirely random. It should not be used for applications requiring cryptographically-strong randomness or uniform probability distributions.
