Randomize Statement

Инициализирует генератор случайных чисел, используемый функцией Rnd.

Синтаксис

Randomize [Число]

Параметры:

Number: Any integer value. Used as seed to initialize the random-number generator. Equal seeds result in equal random-number sequences by the Rnd function. If the parameter is omitted, the Randomize statement will be ignored.

Unless a predictable sequence of numbers is desired, there is no need to use the Randomize statement, as the random-number generator will be initialized automatically at first use – it will be seeded using a system-provided random-number generator that produces uniformly-distributed, non-deterministic random numbers. If no such generator is available on the system, the system time will be used as seed.

The Randomize statement affects BASIC's Rnd function only. Other random-number generators (for example the Calc's RAND() function, etc.) are not affected by it.

Пример:

Sub ExampleRandomize

Dim iCount As Integer, iVar As Integer, sText As String

Dim iSpectral(10) As Integer

    Randomize 2^14-1

    For iCount = 1 To 1000

    iVar = Int(10 * Rnd) ' Диапазон от 0 до 9

        iSpectral(iVar) = iSpectral(iVar) +1

    Next iCount

    sText = " | "

    For iCount = 0 To 9

        sText = sText & iSpectral(iCount) & " | "

    Next iCount

    MsgBox sText,0,"Спектральное распределение"

End Sub
