DotNet Division Bug?

alexrazon — Wed, 15 Jul 2009 05:13:00 GMT

Here's an interesting exercise for the day.

In Visual Studio 2005/2008,

1. Create a new Console Application.

2. Put in the following code in Main:

double x = 5.15;
double y = x / 100;
Console.WriteLine("y = " + y);

3. Put a breakpoint at the Console.Writeline(..).

4. Press F5 to debug the application.

5. Watch the value of y. What is its value in the watch window?

6. Press F10 to continue with the console write. What is the value of y as displayed?

Do the same for x=4.15, x=6.15,x=7.15,x=8.15.... What are the values displayed?

Try also to divide by 10 or 1000 using the same set of values for x. (E.g. 4.15/10, 6.15/1000). What is the resulting value for y?

Using pen and paper, what are the supposed results? :)

Hint: It appears that there are extra values for the results using x=5.15, x=6.15, and x=7.15. Weird eh?
