    // Use standard numeric format specifiers.
    specifier = "G";
    System.Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

    specifier = "C";
    System.Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

    specifier = "E04";
    System.Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

    specifier = "F";
    System.Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

    specifier = "N";
    System.Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

    specifier = "P";
    System.Console.WriteLine("{0}: {1}", specifier, (value/10000).ToString(specifier));
    
    // Use custom numeric format specifiers.
    specifier = "0,0.000";
    System.Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

    specifier = "#,#.00#;(#,#.00#)";
    System.Console.WriteLine("{0}: {1}", specifier, (value*-1).ToString(specifier));
    
  }
}

The code above generates the following result.
