Return 使用 Excel VBA 公式得出的 ABS 值

Question

在下面给出的代码中，那是，我现在试图从等式中获得绝对值。我尝试使用 ABS() 命令：

.Formula = "=IF(ISNUMBER(" & strLowLimCol & "2)," & _ strMeasCol & "ABS(2-" & strLowLimCol & "2," & _ strMeasCol & "2))"

我认为我没有正确执行命令。你能帮我从等式中得到绝对值吗？

代码如下：

Option Explicit

Sub ReturnMarginal()

    Dim ws As Worksheet
    Dim lngLowLimCol As Long, strLowLimCol As String
    Dim lngHiLimCol As Long, strHiLimCol As String
    Dim lngMeasCol As Long, strMeasCol As String
    Dim lngLastRow As Long
    Dim wsf As WorksheetFunction

    ' get worksheetfunction references
    Set wsf = Application.WorksheetFunction

    ' iterate worksheets
    For Each ws In ThisWorkbook.Worksheets

        ' validate LowLimit label is on sheet
        If ws.Rows(1).Find("LowLimit") Is Nothing Then Exit Sub

        ' get location of input data columns and number of rows
        lngLowLimCol = wsf.Match("LowLimit", ws.Rows(1), 0)
        lngHiLimCol = wsf.Match("HighLimit", ws.Rows(1), 0)
        lngMeasCol = wsf.Match("MeasValue", ws.Rows(1), 0)
        lngLastRow = ws.Cells(1, lngLowLimCol).End(xlDown).Row

        ' get column letters for input data columns
        strLowLimCol = Split(ws.Cells(1, lngLowLimCol).Address(True, False), "$")(0)
        strHiLimCol = Split(ws.Cells(1, lngHiLimCol).Address(True, False), "$")(0)
        strMeasCol = Split(ws.Cells(1, lngMeasCol).Address(True, False), "$")(0)

        ' output headers
        ws.Range("P1") = "Meas-LO"
        ws.Range("Q1") = "Meas-Hi"
        ws.Range("R1") = "Min Value"
        ws.Range("S1") = "Marginal"

        ' assign formulas to outputs
        ' Meas-LO
        With ws.Range("P2:P" & lngLastRow)
            .Formula = "=IF(ISNUMBER(" & strLowLimCol & "2)," & _
                strMeasCol & "2-" & strLowLimCol & "2," & _
                strMeasCol & "2)"
        End With

        ' Meas-Hi
        With ws.Range("Q2:Q" & lngLastRow)
            .Formula = "=" & strHiLimCol & "2-" & strMeasCol & "2"
        End With

        ' Min Value
        With ws.Range("R2:R" & lngLastRow)
            .Formula = "=MIN(P2,Q2)"
        End With

        ' Marginal
        With ws.Range("S2:S" & lngLastRow)
            .Formula = "=IF(AND(R2>=-3,R2<=3),""Marginal"",R2)"
        End With

    Next ws

End Sub

最简单的方法是将 Abs 放在整个公式周围：

.Formula = "=ABS(IF(ISNUMBER(" & strLowLimCol & "2)," & _
            strMeasCol & "2-" & strLowLimCol & "2," & _
            strMeasCol & "2))"

但是如果你愿意，你可以把它放在每个组件周围：

.Formula = "=IF(ISNUMBER(" & strLowLimCol & "2),ABS(" & _
            strMeasCol & "2-" & strLowLimCol & "2),ABS(" & _
            strMeasCol & "2))"

你必须记住的是 strMeasCol & "2-" & strLowLimCol & "2 正在使用两个地址创建一个公式，例如 G2-K2 - 所以你不能通过它开始 ABS （即你在我的示例地址中将 ABS( 放在 G 和 2 之间，给出类似 GABS(2-K2 的内容）。
