Converting To String Removes 0's after Decimal

Question

I am copying data from a source workbook to a destination workbook by using the Implode() method below. The issue that I have is that in the source workbook the format will be 7.00 but in the destination workbook the format will be 7, I believe this is due to CStr(MyR(1, i)) i.e. ConvertToString. How can I alter this method so that if the column is in a numeric format that once it is copied to the destination workbook, it is once again in a numeric format?

Private Function Implode(ByVal R As Range, Optional ByVal D As String = strSeparator) As String
    Dim i As Long, ii As Long, str As String, MyR() As Variant
    MyR = R
    For i = 1 To R.Columns.Count
        isPercent = False
        If iPC > 0 And IsNumeric(MyR(1, i)) And MyR(1, i) <> "" Then
            For ii = 1 To iPC
                If i = PercCols(ii) Then
                    isPercent = True
                    Exit For
                End If
            Next ii
        End If
        str = CStr(MyR(1, i))
        If InStr(1, str, D) > 0 Then str = """" & str & """"
        If i = 1 Then
            Implode = str
        Else
            Implode = Implode & D & str
        End If
    Next i
End Function

Can try

 If IsNumeric(MyR(1, i)) Then 'Check for numeric
      Round(CDec(MyR(1, i)),2)
 Else
      CStr(MyR(1, i))
 End If

CDec allows those without decimal to be displayed as whole numbers
