在Excel VBA中生成随机数,你可以使用Rnd函数。Rnd函数用于生成一个大于等于0且小于1的随机数。如果你需要生成特定范围的随机数,可以通过调整Rnd`函数的返回值来实现。 示例1:生成0到1之间的随机数 v Sub GenerateRandom0To1() Dim randomNumber As Double randomNumber = Rnd() MsgBox "随机数:" & random...
打开Excel,并按下Alt + F11进入VBA编辑器; 在VBA编辑器中,点击插入菜单,然后选择模块; 在新建的模块中,输入以下代码: Sub GenerateUniqueRandomNumbers() Dim rng As Range Dim cell As Range Dim uniqueNumbers() As Variant Dim randomNumber As Double Dim i As Integer '设置随机数范围 Set rng = Range(...
按下Alt + F11打开VBA编辑器。 插入一个新模块。 在新模块中编写自定义函数的VBA代码,例如: Function GenerateRandomNumber(ByVal Min As Double, ByVal Max As Double) As Double Randomize GenerateRandomNumber = WorksheetFunction.RandBetween(Min, Max)End Function 4. 保存并关闭VBA编辑器。 5. 在Excel工作...
可以用字符串先连接起已生成的数字,再判断新数字是否已存在于旧字符串中,如果存在的话就重复再跑一次即可: SubCreateRandomUniqueNumbers()DimrngAsRange,randNumberAsInteger,randNumberStringAsStringForEachrngInActiveSheet.Range("A1:A5")Repeat:randNumber=Application.WorksheetFunction.RandBetween(1,5)IfVBA.InStr(r...
如果上面的公式让你有点难以理解,你可以应用下面的VBA代码,请这样做: 1。 按住ALT + F11键打开Microsoft Visual Basic应用程序窗口。 2。 点击插页>模块,然后将以下代码粘贴到模块窗口。 VBA代码:生成没有重复的随机数 Sub Range_RandomNumber() Updateby Extendoffice Dim xStrRange As String Dim xRg, xCell...
打开VBA 编辑器(快捷键Alt + F11),插入一个新模块,并输入以下代码: Sub GenerateFixedRandomNumber() Dim ws As Worksheet Set ws = ActiveSheet ws.Range("A1").Value = Int(Rand() * 41 + 60) ' 假设随机数生成在 A1 单元格 End Sub 运行这个宏,它会在指定单元格中生成一个随机数并固定下 ...
ll look at is theRANDfunction and some of its variations. Once we have that down, we’ll write a simple macro to generate random numbers, too. Ultimately, macros will give you the most comprehensive power, and you canlearn all about their amazing capabilities in this macro and VBA ...
Formula 1: Generate random numbers with decimals in Excel by Randbetween() (Simplest) What we are trying to do To generate random number between 50 to 80 with 2 decimal places Using Randbetween() the traditional way, we would have got random integer like 62, 71 or so. Therefore, we are...
We can extend the value of the RAND function to a larger range by simply multiplying the function value by the desired range. So, to generate a random number Y that satisfies 0 <= Y < 100, use =100*RAND() We can shift the number range by adding the desired lowest value. So, to ...
启动VBA编辑器,可以通过按下“Alt + F11”使用。接着,插入一个模块(Insert -> Module),然后输入代码。例如生成1到100之间的随机数,可以使用以下代码: Sub GenerateRandomNumber() Dim rng As Range Set rng = Range("A1:A10") '设定生成随机数的单元格范围 ...
