Answer 1

Use value of html element.

Try this,

double d = double.Parse(webbrowser.document.getelementbyid(something).value);

Answer 2

You could use

double d;
string element = webbrowser.document.getelementbyid(something).Value;
if (Double.TryParse(element, out d))
{
    // Conversion succesful: in d you find your number
}

Take a look at Double.TryParse syntax.

Answer 3

After retrieving the value in string form, you should use Double.TryParse to parse it as a double, e.g.:

double number;

if (Double.TryParse(webbrowser.document.getelementbyid(something), out number))
{
   // ... do something useful with 'number' ...
}

Answer 4

I assume you're trying to do something like this;

string innerHtml = webbrowser.Document.GetElementById(something).InnerHtml;
double value;

if(Double.TryParse(innerHtml, out value))
{
    // value is now populated
};
