Since, the 0 after the decimal point without any number following it does not have any significance as a value it is not available in the double value.

However, while representing the double number as a string it can be shown using an appropriate Format specifier as follows:

C#

double value = 100;
string valueAsString = value.ToString("N1");
Console.WriteLine (valueAsString);
//Output
//100.0

To show commas etc. other Formats given here http://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.71).aspx[^] can be used.
