Remove decimal place (not saving variable as int)

[Crzyrio]

Dim minimumValue As String

if i change it, it renders ' minimumValue = minimumValue.Replace(".", "")'
as useless since that is for a string. How can I use a replace function to change the decimal to nothing,
and if i change it to a double

will that work?

Take a look at this and see if it makes sense

Imports System.Text
     
    Public Class Form1
        Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
            Dim x As String = GetNumber("9.99")
            Dim newbuilder As New StringBuilder
     
            If x.Count < 10 Then
                MsgBox(x.Count)
                newbuilder.Append("0", 10 - x.Count)
                newbuilder.Append(x)
            End If
            x = newbuilder.ToString
            MsgBox(x)
     
        End Sub
        Function GetNumber(ByVal theString As String) As String
            Dim sa() As Char = theString.ToCharArray
            Dim builder As New StringBuilder
     
            For Each n In sa
                If IsNumeric(n) Then builder.Append(n)
            Next
            Return builder.ToString
        End Function
    End Class

Dim newbuilder As New System.Text.StringBuilder

        If minimumValue.Count < 10 Then
            newbuilder.Append("0", 10 - minimumValue.Count)
            newbuilder.Append(minimumValue)
        End If

minimum value is the variable. Is that correct? It still doesnt work. I changed line 1 because there was a syntax error. Is that even right?

TRY THIS :

Dim newbuilder As New System.Text.StringBuilder
 
        If minimumValue.Count < 10 Then
            newbuilder.Append("0", 10 - minimumValue.Count)
            newbuilder.Append(minimumValue)
        End If
minimumValue = newbuilder.tostring
