I've seen this issue in php and javascript. I have this number: float 0.699
if I do this:
0.699 x 100 = 69.89999999999999
why?
edit
round(0.699 x 10, 2): float 69.90000000000001
I Have dynamically render row. WE have fields like FROM TO.
For eg: From TO

2 10,
0 1,
11 12
This combination is allowed.the row may also increased.

I am not sure if you can post revision programming questions in here but i am stuck with some algorithms revision
If an algorithm is quadratic it takes time proportional to the number of n^2 ?
So if the slides say its almost 1/2 the square of n records is this the same as saying (n^2 * 0.5)
Thanks

I have a scenario where I need to send a series of data across 2 clients.
The data includes Serialized XML that will contain commands that the other client will need to react to.
I will also need to send images across the wire as I need to provide a chat facility in the form of video/audio chat.
I would like a single communication medium for both, as the number of messages/commands might be a few.
WCF or Sockets?

I have a number of classes that are decorated with DebuggerDisplayAttribute.
I want to be able to add trace statements to Unit Tests that will display instances of these classes.
Does there exist a method in the .NET Framework that will display an object formatted using DebuggerDisplayAttribute (or fall back to using .ToString() if no DebuggerDisplayAttribute is defined)?
I have a 200kb file, what I use in multiple pages, but on each page I need only 1-2 lines of that file so how I can read only these lines what I need if I know the line number?
For example if I need only the 10th line, I don`t want to load in memory all the lines, just the 10th line.

If the data in one of the column in table is more than say 800 bytes, it seems to print partial pages. Previews also appears same (span into multiple partial pages).
What is the best way so that large number of rows with wide coulumns (fixed width) are printed properly without giving blank or partial page.
Used table with thead and colgroup with width in 14%.

It turns out our slaves spend a considerable amount of time moving the archived artifacts back to the master Hudson node. It at least triples the duration of the build. It would be nice if there would be a way to prevent it. However, setting the maximum number of builds to keep doesn't have an influence at all. Is there another way to prevent sending the results back to the central Hudson master?
I'm have a number rows I'm inserting into a table using -insertRowsAtIndexPaths:withRowAnimation, and I would like the rows to be indented from the left to distinguish them from the rest of the cells. The indentationLevel property of UITableViewCell looks like it's exactly what I need, but it doesn't seem to do anything. Here's the code I'm using to set the indentation level (dot syntax doesn't make a difference):
[cell setIndentationWidth:10];
[cell setIndentationLevel:1];
Is indentationLevel what I want, or should I be looking elsewhere?

Hi all
There are a lot of numbers like 200 20.5 329.2...in a file. Now, I need replace every number A with A*0.8. Is there any simple method to replace original value with another based on original value?
Best Regards,
It used to be the number one reason for us to choose MSTest from others that we could access and test private methods. Now that Private accessors are deprecated in Visual Studio 2012. Does anyone know why Microsoft make such decision? Is it because it's not a good practice to test private methods?
Also, if I still need to unit test my private methods, how could I do that in VS 2012 and later versions?

I have asp:Table with number of asp:Label inside asp:FormView, it represents short stats info.
I need to set Label.CssClass to "red" if it's text isn't "0".
Currently I do this on FormView.DataBound event. But think that it's better to use JavaScript and probably jQuery. How can I do that?
