excel中,B1和B2输入两个数,使用vba生成9个小数点后保留两位的随机数,要求在B1与B2之间,且9个随机数中最大的随机数与最小的随机数的差不能超过0.04,最后将9个随机数填到C4-C12中

在Excel VBA中,你可以编写一个宏来实现这个功能。首先,你需要创建一个新的模块,然后编写以下VBA代码:
```vba
Sub GenerateRandomNumbers()
Dim rng As Range
Dim maxNum As Double
Dim minNum As Double
Dim randomNumbers() As Double
Dim i As Long
' Set the range for input values
Set rng = Range("B1:B2")
' Get the minimum and maximum values from B1 and B2
minNum = rng.Cells(1, 1).Value
maxNum = rng.Cells(2, 1).Value
' Check if the difference between max and min is less than 0.04
If maxNum - minNum <= 0.04 Then
MsgBox "The range is too small to generate 9 numbers with a difference of 0.04.", vbExclamation
Exit Sub
End If
' Create an array for 9 random numbers within the range
ReDim randomNumbers(1 To 9)
For i = LBound(randomNumbers) To UBound(randomNumbers)
randomNumbers(i) = Int((maxNum - minNum + 0.01) * Rnd) + minNum ' Adding 0.01 ensures at least one decimal place
Next i
' Sort the array to find min and max
Application.Sort source:=randomNumbers, Order1:=xlAscending, Header:=xlNo, MatchCase:=False
Dim diff As Double
diff = randomNumbers(UBound(randomNumbers)) - randomNumbers(LBound(randomNumbers))
' Ensure the difference doesn't exceed 0.04 after sorting
If diff > 0.04 Then
MsgBox "Failed to generate random numbers within the specified conditions.", vbExclamation
Exit Sub
End If
' Insert the random numbers into C4-C12
For i = 4 To 12
Cells(i, 3) = Format(randomNumbers(Application.Rank(i - 3, randomNumbers, True)), ".00") ' Round to two decimal places
Next i
End Sub
```
运行`GenerateRandomNumbers`宏后,它会在B1和B2范围内的九个随机数会按照上述条件填充到C4至C12单元格。如果无法满足条件,程序会显示警告信息。
