在VBA 中,要确定一个变量是否是整数,可以使用TypeName()函数和IsNumeric()函数进行检查。以下是一个示例代码: 代码语言:vba 复制 Sub CheckIfInteger() Dim variable As Variant variable = 10 If IsNumeric(variable) And TypeName(variable) = "Integer" Then MsgBox "The variable is an integer." Else MsgB...
If fromThis.Value Like "*.*,*" Then european = True End If For i = 1 To Len(fromThis)ltr = Mid(fromThis, i, 1)If IsNumeric(ltr) Then retVal = retVal & ltr ElseIf ltr = "." And (Not european) And Len(retVal) > 0 Then retVal = retVal & ltr ElseIf ltr = "," And eu...

3. Check if a Cell Contains a Number Here we have used a condition to check whether theactive cellcontains a numeric value or not. Sub check_number() If IsNumeric(Range("B2").Value) Then MsgBox "Yes, active cell has a number." ...
For Example: If you want to remove first characters from a cell, you need to enter 1 in cnt. 75. 在 Excel 中添加插入度数符号 Sub degreeSymbol( ) Dim rng As Range For Each rng In Selection rng.Select If ActiveCell <> "" Then If IsNumeric(ActiveCell.Value) Then ActiveCell.Value = ...
