Single Structure under C#

To know size of a value type you could probably use below,

static void Main(string[] args)
{
    Console.WriteLine("{0}",sizeof(Single));
}

:)

You call single a structure? It is a structure in fact? Yes and no. All primitive types comes in their original form or in a boxed form. Only a boxed form is a structure. These two forms have different size (boxed is larger; also, it's a class).
