Format double output with dot instead of comma

Question

I have a collection of coordinates to popular the Peater, with city name, latitude and longitude.

 .aspx

 <form id="form1" runat="server">

    <div id="repetidor">
        var markers = [
                <asp:Repeater ID="rptMarkers" runat="server" Visible="true">
                <ItemTemplate>
                  cidade: <%# Eval("NomeCidade")%>,
                     lat: <%# String.Format(System.Globalization.CultureInfo.GetCultureInfo("en-US"), "{0:D}", Eval("Latitute")) %>,
                     lng: <%# String.Format(System.Globalization.CultureInfo.GetCultureInfo("en-US"), "{0:D}", Eval("Longitude")) %>,
                </ItemTemplate>
            <SeparatorTemplate>
                    -
            </SeparatorTemplate>
                </asp:Repeater>
        ]
    </div> 

I’ll get the coordinates like this;

     .aspx.cs            

       (...)
                var address = coordenadas.NomeCidade + ", Brasil";
                var locationService = new GoogleLocationService();
                var point = locationService.GetLatLongFromAddress(address);
                coordenadas.Latitude = point.Latitude;
                coordenadas.Longitude = point.Longitude;
                coordenadasColecao.Add(coordenadas);

        (...)
            rptMarkers.DataSource = coordenadasColecao;
            rptMarkers.DataBind();
        (...)

I’d like it to come out like this: 46.1475292 instead of 46.1475292

Answer 1

I don’t know how you’re getting this amount, because usually it comes with dot, as can be seen on the official Github of the API you are using.

But you can make a simple Replace(), if you wish.

Console.WriteLine(String.Format(System.Globalization.CultureInfo.GetCultureInfo("en-US"), "{0:D}", "46,1475292").Replace(",","."));

You also have the strings to format the way you want.

Otherwise, you can look at the question of How to Format Double I think you’ll have a few more ideas on how to do what you want.

Answer 2

Make the conversion to String then use the command Replace of string class:

<%#Eval("Latitude").ToString().Replace(",",".")%>

References:

• String class

• String.Replace method (Char, Char)

Answer 3

Utilize String.Format and also force with the Globalization

<%# string.Format(new System.Globalization.CultureInfo("en-US"), 
                              "{0:D}", Eval("Latitude")) %>
