I have a feeling that I'm doing things all ass-backwards (again ;-),
and would like some advice. What I want to do is:
put some data to memory and then access that memory space as an array
of data-types of my choosing (eg an array of char, short, or int).

This question has probably been asked a million time, but here it comes
again. I want to learn the difference between the three type cast operators:
static_cast, reinterpret_cast, dynamic_cast. A good way to do this is by
example. So I will give an example and please tell me what you think:
I have a base
class A
with a virtual destructor,...

SELECT sum(cost_of_sale)/sum(price) AS division2 FROM testsums;
The first select gives 0.333333333333333333333333

Hi there,
Is there anyone that knows how to do the following?

of time trying to track down the issue.
Basically put the following code into your C# app:
float testFloat2 = (int) (4.2f * (float)100);
Console.Out.WriteLine("1: "+testFloat2);
and the result...

This is as boiled down as I can make it. ...
