1.Q: double scientific

Hiya

I've just discovered something when writing numbers in scientific notation 
in source code. If you write something like

1.83607E-5

Visual Studio changes it to

0.0000183607

Is there a way to stop the Visual Studio environment from doing this?

Thanks

2.Scientific Notation when serializing doubles

Hi. We put data on MSMQ queues using the Message ctor as follows:

Message myMessage = new Message(myObject);

As I understand it, this will use an XmlSerializer to serialize the body of 
the message when it is placed on the queue. We have noticed that if myObject 
contains doubles with small values (e.g. 0.0000000001) the serilized object 
will represent these values in scientific notation (e.g. 1E-10). 

Is this standard behaviour of the XmlSerializer, and is there any workaround?

Thanks

3.Parsing scientific format String to double

I've got errors when parsing the string
"1.234e+002" to a double. I used the 
invariant culture to endure that the 
comma is not an issue and i pucked the
styles of the number to be float, to 
ensure that scientific format is OK.

   double dbl = double.Parse(
      "1,34e+002", 
      NumberStyles.Float, 
      CultureInfo.InvariantCulture);

Still, i get errors. The error message
is rather undesciptive, telling me only
that the format of the string is wrong.

Of course, i also tried the following, 
just to make sure it's not THAT simple.

   double dbl = double.Parse(
      "1.34e+002", 
      NumberStyles.Float);

Still, to no avail. What exactly is 
wrong here? How do i remedy it?

4.Error in "double = double - double" statement

I am trying to compute the differnece between two dwords in visual basic and
keep getting the wrong value being computed.  I have the following structure
defind:

Public Type HighLowQuote
    TradeDate As String
    OpenPrice As Double
    HighPrice As Double
    LowPrice As Double
    ClosePrice As Double
    Volume As Long
    AdjClosePrice As Double
    AmtChange As Double
End Type

I create an instance of this type as 'q'.  I then do the following:
q.highprice = variant
q.lowprice = variant

at this point the locals variable window shows the values as:
q.highprice = 4.1
q.lowprice = 4

I then fall through the following code:
q.AmtChange = q.highprice - q.lowprice

q.amtchange is then valued at 9.99999999999996E-02 in the locals window when
I believe it should be valued at .1.

Why is the value not being set to .1?  Is there a change I can make to get
this calculation to work how I expect or is there some other way to perform
these calculations to get the results I am after?

Any help would be appreciated.  Thanks in advance.
