I am started learning .net. I want two decimal points value. I have used this codelblNo.Text = Math.Round(CDec(txtNo.Text + (txtNo.Text * 0.2)), 2).ToString(If i have value as 1.32 then its ok but if i have value like 2.3 it shows 2.3 but i want value as 2.30

I have two functions that return a dollar amount but one of the amounts extends out to more than 2 decimal positions. So I'm trying to round it to two decimal positions and for some reason after the amounts are added together it goes back to extending out more than 2 decimals. I have tried several things. Currently I'm trying to even use a string variable in-between conversions to see if I can get rid of the decimal values but it's still not working.
Here is the first function.
Public Function dTotalDollars(Optional ByVal iClassAccountIndex As Short = -1, _
Optional ByVal iBreakdownCode As DOLLAR_AMOUNT = DOLLAR_AMOUNT.ALL_DOLLARS) As Double
Dim dAmount As Double
[Code].....
Then after the second call it's showing in debug mode that dTotalCalcDollars is going to return 2272.37, but once it adds it to dAmount the amount becomes 28094.739999999998 instead of 28094.74.
I have a dataset that contains decimal values pulled from a database, when I try to assign the values in it to variables, the decimal values somehow got rounded to a whole number. I have manually ran the query which selects a column of decimal(18,4) datatype and verified that the output contains decimal places. During the breakpoint, I also found out that the (dtr(c.ColumnName)) actually becomes an integer.
Dim bannerValsAmt(1) As Decimal
Dim bannerVals(1) As String
Dim i As Integer

I wish to display values of 2 decimal places whenever this field (datatype = smallmoney) is being read & displayed via a SQL select statement. Is there a simpler way out besides the following example? Im using VS 2008,
CONVERT(varchar, CONVERT(smallmoney, ABS(reading_i - reading_f)), 2 )
I have my form set in french as well, and it automatically changes the text format to use ','. However When I try to insert my values into the database it says cannot convert nvarchar to decimal? Worst case, Is there a way I can disable the numbers from changing to use ',' and just use '.' always regardless what language it is? My working language is vb.net?
View 1 RepliesHow would I convert the two individual byte values (in hex) to a decimal value representing the concatenated hex values? For example, if I have the
Dim byte1 As Byte = &H99
Dim byte2 As Byte = &H99
' I want the decimal representation of the hex value "9999" ' (byte1.ToString + byte2.ToString) which should be "39321" Currently I use the following code:
Dim decVal as integer
decVal = Val("&H" + Hex$(byte1).ToString + Hex$(byte2).ToString)
However, when I use this, the value (decVal) comes out to "-26215"
I'm drawing polygons,lines,etc. and I have to have the points of each precise - up to 12 decimals. Since a Point only takes integer values, I'm not sure how to handle scaling. I have a working user control, but rounding the decimals so I can put them into points is causing incorrect calculations (area, ect.).
View 4 RepliesI'm trying to limit the number of decimal values to 3 in numbers such as .3125 but I also have numbers such as .5 which I need to leave as is.
how can I determine if a number is 4 decimal places and cut off the last number.. I don't want to round up either.. .3125 should be .312 not .313 and .5 should stay at .5 and not .500.

View 1 RepliesIs it possible to create a plot from List(Of Decimal) values in Excel with VB? I would like to avoid dumping data directly into a table, then creating the chart from that. Here is what I have so far, but I am getting a data type mismatch when I try to assign .XValues and .Values to the list. Is there some sort of conversion that needs to happen to turn a list into a series?
Dim Series As Excel.Series

Is there such a thing as a type similar to a point, but contains a pair of decimals, or a pair of doubles, rather than integers? I searched the forums and google with no luck. I can't believe this has never come up before, I must have been using the wrong search terms.
View 4 RepliesIn the discussion in this thread: [URL] it was reveiled to me that vb.net, using double, could only calculate values up to 18 digits after decimal.... so I started thinking and came up with this class

I want to split the string into a series of doubles.... and than combine them into a large number.... The size of each double component should be 18 digits on a 32 bit computer... so that I will have room to add the last carrier...
Create a function named DecimalDegrees to refactor the code that converts a latitude or longitude into a value in decimal degrees. (This function will be used inside the functions ValueOf and Distance.)
Task 2a: Write the code for the function DecimalDegrees with an input parameter for DegreeString as type string, and returns the value as type Double.
Here is my code for the function part
Private Function DecimalDegrees(ByVal DegreeString As String, ByVal degrees As Double, ByVal minutes As Double,
ByVal seconds As Double, ByVal ID As Integer) As Double
I am having difficulties with the 2nd part which is I believe to take the code for the calc1 and calc2 buttons and somehow get it to convert to decimal degrees by the function I have created. The buttons would then be removed as the code would automatically take the latitude and longitude and convert the degrees, minutes and seconds into a decimal.
Here is the code for the current buttons:
Dim StartPtr, StopPtr As Integer
'To Replace Calculator 1 Button
'Convert degrees before passing argument - Latitude
StartPtr = 0
