Question

我必须使用什么方法来编写分数，例如使用VB.Net在标签中½？

Answer 1

我找到了一个更好的选择，即使用RichTextBox而不是使用Label。将RichTextBox拖到Form上，然后使用快捷键键入fraction。

Answer 2

Function GetFraction(ByVal d As Double) As String
    ' Get the initial denominator: 1 * (10 ^ decimal portion length)
    Dim Denom As Int32 = CInt(1 * (10 ^ d.ToString.Split("."c)(1).Length))

    ' Get the initial numerator: integer portion of the number
    Dim Numer As Int32 = CInt(d.ToString.Split("."c)(1))

    ' Use the Euclidean algorithm to find the gcd
    Dim a As Int32 = Numer
    Dim b As Int32 = Denom
    Dim t As Int32 = 0 ' t is a value holder

    ' Euclidean algorithm
    While b <> 0
        t = b
        b = a Mod b
        a = t
    End While

    'Get whole part of the number
    Dim Whole As String = d.ToString.Split("."c)(0)

    ' Return our answer
     Return Whole & " " & (Numer / a) & "/" & (Denom / a)

End Function

label.text = GetFraction（0.5）

此功能会在标签中将0.5转换为1/2 该功能将返回0 1/2 要省略0更改 - 不要返回“整体”

VB.Net如何在标签中写分数？
