Zero-Rounding-Error Class In .Net?
Oct 28, 2011
I was wondering is there a class in .Net that is used to calculate precise numbers with no rounding errors? Of course this is just an example implementation. Basically the main point here is I'm searching for a class that does not have any rounding errors (usually by delaying calculations to the last moment).[code]I understand that performance would be slower than Double or Decimal. But it doesn't have to do calculations blindly fast, as long as it is within acceptable time.[code]

I'm having a problem with a class issue in VB 2005. The error message reads "The class Tellerform can be designed, but is not the first class in the file. Visual Studio requires that you use the first class in the file. Move the class code so that it is the first class in the file and try reloading the designer again."

I get the following error when trying to compile the simplest prpgram. Error 1 Class 'CLSID_CorSymWriter' could not be created: System Error &H80040154& After looking at other stuff on the net I removed VB 2010, VB 2008, any C or C++ runtimes and any .NET Framework programs I could find, and then re-installed VB 2010, but the problem still persists.

I have very basic question, I'm really not familiar with vb.net.
I have code like this: Dim minutes As Integer = (55 / 60)
I want this to return 0 to me, integer 0 (no decimals), but vb.net rounds this to 1.
Can someone hint me up how to accomplish this ?
edit. OK for those with same problem try dividing with (Yeah, it's not escape character in vb.net)

I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.
But I was getting errors on the pattern created.
My approach was to use a substring containing a number copied from the label names:
Num = Val(sender.name.substring(5))
And the subindexes of the matrix:
p = (Num - 1) / 5
q = (Num - 1) Mod 5
The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)
So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _

I need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.
like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124
I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.

What is the rounding method that VB.NET uses when a double is used in a for statement like this. It looks like 5.5 is rounded to 6 and 10.5 is rounded to 10. The output of the program is 6 7 8 9 10
Sub Main()
Dim A As Double
Dim B As Double

I'm using the following code to show the percentage of correctly answered questions
Percentage.Text = rightAnswers / 60 * 100 & "%" There are 60 questions and if the user answers 8 correctly the above code shows the answer as 13.33333333..%
How can i round it off to just whole numbers e.g. 13%?

Im working on a program that is about to drive me nuts figuring out how to round and show only 3 or 4 numbers past the decimal placement and also show the scientific notation.
Here is an example of the code.[code...]
The problem here is that most of these calulations turn up so long that my text boxes just show a small portion of the answer. I have really investigated rounding and decimal placement but nothing seems to work...does anyone have a solution?

I'm a college student, working on a small project, and I'm having some trouble understanding the Round command on VB. The project is very simple and straight forward, just a simple Bail Bonds program to calculate the bail plus a 10% fee. However, i want to integrate a kind of "promotion", where for every $1000 of the bail cost, $5 would be deducted. I know the formula for this, which is reasonable simple, i just need to know how to round the Bail variable to the nearest 1000 so i can do this calculation.
