Question

下面是我创建的VBA函数，用于在Excel中将脚的测量值从数字转换为文本。例如，函数将采用数字1.5并将其转换为字符串：1'-6“。

出于某种原因，它错误地将11.5英寸的值舍入。当单元格设置为'= 11.5 / 12'（11.5英寸表示为英尺）时，结果为0.9583，重复3。当我将此值传递给我的txtfeet（）函数时，它返回字符串1'-0“。真正的答案应该是字符串11 1/2”。

该功能适用于其他重复数字，如9.5英寸（0.7916，重复6次）。奇怪的是，如果我将它传递到1英尺和11.5英寸（换句话说，1.9583，重复3次），它也可以正常工作。

任何人都可以帮忙修复此错误吗？

这是我的功能代码。

Public Function txtfeet(FeetIn As Double, Optional Denominator As Integer = 8)

' This function will change a decimal number of feet (FeetIn) to the text string
' representation of feet, inches, and fractional inches.
'
' It will round the fractional inches to the nearest 1/x where x is the denominator
' and is given by the user as the second argument of this function.  If a denominator
' is not given, it defaults to 8 as shown above.

    ' set a variable to the integer portion of FeetIn
    NbrFeet = Fix(FeetIn)

    ' set a variable to the number of inches in decimal form
    InchIn = (FeetIn - NbrFeet) * 12

    ' set a variable to the integer portion of InchIn
    NbrInches = Fix(InchIn)

    ' set a variable to the remaining fractional inches in decimal form
    FracIn = (InchIn - NbrInches) * Denominator

    ' set a variable to be FracIn rounded to the nearest whole number
    Numerator = Application.WorksheetFunction.Round(FracIn, 0)

    ' if the fractional inches are zero, define the portion of text
    ' that will represent the fractional inches to be blank
    If Numerator = 0 Then
        FracText = ""

    ' otherwise, if the number of inches plus the fractional inches rounds up to
    ' 12, add one to NbrFeet and set NbrInches to zero and FracText to blank
    ElseIf (InchIn + (Numerator / Denominator)) = 12 Then
        NbrFeet = NbrFeet + 1
        NbrInches = 0
        FracText = ""

    ' otherwise, if the numerator equals the denominator, add one to NbrInches
    ' and set FracText to blank
    ElseIf Numerator = Denominator Then
        NbrInches = NbrInches + 1
        FracText = ""

    ' otherwise, define FracText in its simplest fractional form
    Else
        ' use a loop to get the fractional inches to their simplest form
        Do
            ' if the numerator is even, divide both numerator and divisor by 2
            If Numerator = Application.WorksheetFunction.Even(Numerator) Then
                Numerator = Numerator / 2
                Denominator = Denominator / 2
            Else
                FracText = " " & Numerator & "/" & Denominator
                Exit Do
            End If

    End If

    ' define the output of the function as a text string of feet, inches, and
    ' fractional inches or just inches and fractional inches if NbrFeet is zero
    ' or just fractional inches if both NbrFeet and NbrInches are zero

我相信你的行

ElseIf (InchIn + (Numerator / Denominator)) = 12 Then
    NbrFeet = NbrFeet + 1
    NbrInches = 0
    FracText = ""

应该是

ElseIf (NbrInches + (Numerator / Denominator)) = 12 Then
   NbrFeet = NbrFeet + 1
NbrInches = 0
FracText = "

为什么此VBA功能不正确舍入？
