I need to do some math that involves truncating the number after the tenths place. So, I need to take some calculation and remove all digits after the first decimal place without rounding.

For example

3765/3700 * 100=101.75675675675675675675675675676

But, I need to produce from that calculation 101.7. Not 101.8 (the rounded form). Is there a built in method that performs this sort of calculation, or some other way that you might suggest? Thanks.

Hello,

If you want to show it as a string, you could use the String.Format method.

int numberofdecpoints= 10;
double d = 3765/3700 * 100;
string roundednumber =  String.Format("{0:F"+ numberofdecpoints.ToString() +"}",d);

All the best,

Martin

May not be the prettiest

double d = 101.75675675675675675675675675676;<br />
string s = string.Format("{0:f2}", d);<br />
d = Convert.ToDouble(s.Remove(s.Length-1));

Using the specifier {0:f1} still rounds the number to 101.8, so use 0:f2 and truncate it.

only two letters away from being an asset

Can't you just do this?

<br />
double d = 128.158676;<br />
Convert.ToDouble(Convert.ToInt32(d * 10)) / 10;<br />

double d = 101.75675675675675675675675675676;
d = Math.Floor(10 * d) / 10;

Now d has a value of 101.7
Hope this helps

There isn't one. It is a new feature of Visual Studio 2005.

For VS2003, you will need to use an external application such as Visio. The class designer was added in VS2005.

It is a new feature which is available in VS2005 only.

How many people does it take to say this? Both Pete and I already mentioned this. Pete also added a possible alternative which gave some new and potentially useful information.

It sounds like you are attempting to write a keylogger. I don't think many people will want to help you with that endevour, unless you can give a legitimate reason for wanting to do this.

I can't think of a legitimate reason that you would want to do this. Kindly enlighten me as to what you are trying to do. Alternatively, hand yourself in at the nearest police stations because you are trying to write a keylogger which is a VERY BAD thing to do.

Putting roses in your text is not likely to get anybody here to help you become a hacker.

Yeah, I thought that was a really nice touch. However, he ought to learn that most people realise roses are usually quite thorny.

As other people have said, noone is going to help you until you've managed to convince us that you're not doing this for malicious reasons. "My boss said we need it" is not going to work.

Hi,
I believe that the column which is going to be validated is passed in the Event arguements. So you can have it in KeyDown/Validating etc events.
I dont have development environment setup to tell u exactly.

hi,
Thats the beauty of OOP, Create instances of Textbox class at runtime, give them Ids, text, set the desired location to be displayed on the form. Thats it!
