Excel用自定义函数提取单元格内字符串中的数字（VBA代码）

Question

求提取数字达到右边的效果，请问怎么实现？——————————————————————我试了一个代码，对小数不能实现正确提取，请问怎么解决，请大侠帮忙。Function GetNums(rCell As Range, num As Integer) AsStringDim Arr1() As String, Arr2() As StringDim chr As String, Str As StringDim i As Integer, j As IntegerOn Error GoTo line1Str = rCell.TextFor i = 1 To Len(Str)chr = Mid(Str, i, 1)If (Asc(chr) < 48 Or Asc(chr) > 57) ThenStr = Replace(Str, chr, "")End IfNextArr1 = Split(Trim(Str))ReDim Arr2(UBound(Arr1))For i = 0 To UBound(Arr1)If Arr1(i) <> "" ThenArr2(j) = Arr1(i)j = j + 1End IfNextGetNums = IIf(num <= j, Arr2(num - 1), "")line1:End Function
Function GetNums(rCell As Range, num As Integer) AsString
Dim Arr1() As String, Arr2() As String
Dim chr As String, Str As String
Dim i As Integer, j As Integer
On Error GoTo line1

Str = rCell.Text
For i = 1 To Len(Str)
chr = Mid(Str, i, 1)
If (Asc(chr) < 48 Or Asc(chr) > 57) Then
Str = Replace(Str, chr, "")
End If
Next

Arr1 = Split(Trim(Str))
ReDim Arr2(UBound(Arr1))
For i = 0 To UBound(Arr1)
If Arr1(i) <> "" Then
Arr2(j) = Arr1(i)
j = j + 1
End If
Next

GetNums = IIf(num <= j, Arr2(num - 1), "")
line1:
End Function

得看你的字符串啥样子的！

单个数字组，比如: "122test"、逗te344st地、"test987"，这种用内置函数就可以；
多个数字组，比如：逗233test3444test533地；这种都要提取的话得用VBA正则表达式；

追问

逗233test3444test533地
这样的能否给我一个VBA的正则表达式
谢谢
