Randomize Procedure

Randomize Procedure

---

Class

Microsoft.VisualBasic.VBMath

Syntax

 Randomize([   number   ]) 

number (optional; Object or any valid numeric expression)

A number used to initialize the random-number generator

Description

Initializes the random-number generator

Rules at a Glance

• Randomize uses number as a new seed value to initialize the random-number generator used by the Rnd function. The seed value is an initial value that is used to generate a sequence of pseudorandom numbers .

• If you do not pass number to the Randomize procedure, the value of the system timer will be used as the new seed value.

• Repeatedly passing the same number to Randomize does not cause Rnd to repeat the same sequence of random numbers.

Programming Tips and Gotchas

If you need to repeat a sequence of random numbers, you should call the Rnd function with a negative number as an argument immediately prior to using Randomize with any numeric argument.
