I was wondering if someone could explain the logic behind the MidpointRounding enumeration for the Math.Round function. The two enumerations are AwayFromZero and ToEven where, based on the given precision, the former will return the nearest value away from zero toward positive or negative infinity (based on the value's sign) and and letter will provide the nearest even number.

How can I implement my rounding logic?
I understand the concept of rounding I guess, all I know is math.round(), but I need a break down of it so I can round a number like this: 14.789543 to this: 14.8 because after the 7 there is an 8, which means you would round the seven up. Can anyone tell me how this is done?And some more detail, I need to round to the nearest tenth.
View 9 RepliesRecently we have run into an issue with the Math.Round function. We have developed an application in VB.Net 2008. The executable is compiled to use .net framework 2.0. We have deployed the package to our users and at some sites we get a different result in a computation using Math.Round.

I have just received an interesting feedback from a VB.NET customer using our product - for some reason intellisense hidden a certain enumeration value.After a small testing I have found that this is likely a bug in IntelliSense: [URL]..To be honest, I did not expect this problem with such a basic stuff like this. Have you seen this in the past? For me, it doesn't work in all VS versions...
Anyway, feel free to track this issue if you are coding in VB.NET.
does VB.NET include the Mathematical Integration/Derivation functions in the Library? If so where are
they, I couldn't find them? If not, any third-party libraries you would recommend?
I am making a calculator that accepts large number (represented as strings) and performs basic math functions on them. So far I have Add and Multiply figured out.
Here is addition
Private Function Add(ByVal Number1 As String, ByVal Number2 As String) As String
Dim num1, num2, r, total As New Integer
Dim sum As String = ""
[Code].....
I saw something like this in the code bank but the examples there were from VB6(?) and were hugely inefficient (compared his Add and Multiply examples to mine, his having way more code and loops.)
I need a function which will Round a number UP to the specified decimal precision, exactly the same as how Excel's RoundUp function works:
Roundup(dblVal, intDecPlaces)
So I need the following:
Roundup(0.896523, 4)
would return
0.8966
However, everything i've tried/found simply rounds to the nearest whole integer, or returns a normal rounded value, hence the above would return
0.8965
I've tried the following:
Math.Round(dblval, intPrecision, midpointrounding.awayfromzero)
' and
Math.Round(dblval, intPrecision, midpointrounding.toeven)
And even custom functions, such as:
Public Function RoundUp(ByVal varValue As Object, _
ByVal iNum As Integer) As Double
'ignore the data types here, I was playing to see 'if changing any of the data types would swing 'the results (knowing full well they wouldnt make 'a difference, thats how fed up with this I am!)
Dim lNum As Long, xVal As Double, xVar As Object
xVar = Fix(varValue)

I've even looked at converting this to a string, looking at the Xth decimal place, and incrementing it up by 1, then converting it back to a double, while this works (sort of) it seems to be a very roughshod way of doing it, and I'd rather do it mathematically than with lots of data conversion.
I need to execute scripted text formulas. I believe that in VB 6 and/or VBA there was a method EVAL() that did the job, eg: [Code] As it seems, such a method does not exist in VB.NET. [url] The method works fine but due to its comprehensive layout its not that fast (as i need to call it myriad of times) Does anyone have a SIMPLE, FAST, straight forward math expression method? Or anyone knows how to use the old EVAL method in VB.NET?

I have a Windows Forms UI, a Class Library, and a WebService. I need to be able to pass an Enumerated type through each of these layers (SystemType). For instance, the UI passes the type to the class library, which then passes the type to the Web Service.My question is, where do I define this enumeration type so they all know about it.
Options so far:
- Each project contains the exact same enumeration.
- Put the enumeration in its own project and reference this assembly from each of the other projects.
I am trying to figure out if the DayOfWeek Enumeration list can be sorted by using the integer value (ie Sunday = 0). Ultimately I want to take the DayOfWeek Enumeration list and population a dropdownlist with the days of the week from Sunday - Monday and I do not want to hard code the items in the HTML markup. Is this possible?

View 2 RepliesI've been getting the following error from time to time and have been unable to determine the cause of it:"The given key was not present in the dictionary."The line that this is occurring on is:If CType(ViewState("FieldType"), MYClass.FieldType) = MYClass.FieldType.ShowOnDirectory ThenI have no idea as to why it is throwing this exception on this line. I thought that perhaps an invalid value was being placed in the ViewState so I tried while debugging setting the value to Nothing and setting it to a value that wasn't in the enumeration and it still works. I was originally storing the enumeration in ViewState and then went to storing just the Integer equivalent in there
