Causes String To Lose Decimal Place?

Sep 7, 2010

Just to be forward, my .net and c# expierence is very limited, that one could say I'm a complete noob :) However I do have some grasp on OOP as I usually work in PHP (FWIW). My problem seems to be with this line:

Session["total"] = dt.Compute("SUM(price)", "").ToString();

which will output a total of say "9.2" where as the price is "9.20" from a few record lines as such:

dt.Rows.Add(strRecord, 9.20, dropDownListDistrict_stepTitle.Text);
thus 9.20 + 9.20 = "18.40", but the page displays "18.4".

The label that displays the total sum is:

<asp:Label ID="labelTotal3" runat="server" Text="0" />

From what I've gathered, I'm suffering from some kind of type casting problem? Hopefully I haven't missed anything, its a bit difficult to show all the code but hopefully someone can point me in the right direction? Question is; how can I get an extra decimal place to show up on my sum (or why is it dropping the last decimal place?).

Configuration :: Decimal Place - Convert String To Double

Oct 9, 2010

i have a strange error creaping into my web app but am unsure as to how to fix it. When i run this code on my debug workstation it works fine but when i transfer it to my server things seam to go wrong.

dev station (windows 7) + VS2010
regional and language settings all set to uk
server (windows 2008r2)
regional and language settings all set to uk

What seams to be happening is that when converting a string to a double it works correctly on the dev environment but moves the decimal place to the end on the server.

example code(vb)
dim lat as string = "52.983829"
dim long as string = "-0.036500"
dim latint as double = lat
dim longint as double = long

now on the dev server the value of latint is 52.983829 as you might expect but on when published to the server it becomes 52983829.0 the same with longint on the dev staion it is -0.036500 but on the server it becomes -36500.0 i get equally confusing problems if i try to change it to an integer instead.

Forms Data Controls :: Decimal Place Missing After Calculation

May 11, 2010

In a formview I need to present a new value calucalted by dividing one field value by another. I need to present the result to one decimal place. The code I am using is the following, however it presents the resulting value rounded up or down to the nearest whole value:

<asp:label id=lblTotal text='<%# Convert.ToInt32(Eval("Value1")) / Convert.ToInt32(Eval("value2")) %>' runat="server"></asp:label>

I did try and insert refernces to {0:N1} but this just threw asp.net errors. Any advise on how I can guarantee that the value calculated is presented to one decimal place?

C# - Convert Localized String Into Decimal?

Aug 17, 2010

I have a string, that could look like "123,34", "123123,09", "1234", "123.34", "123123.09"

(Stringrepresentation of 10,2 decimal that will be stored into a MySql DB)

Due to the culture of the ASP.net thread may differ, because my application supports localization, I need to find a safe way to convert the most likely user input into a decimal.

How is that possible?

I tried various Decimal.Parse attemps, that all failed so far.

Solution:

My final solution was a mixed one. I used string replace to ensure my date is formatted into the specified CultureInfo I used for parsing

DataSource Controls :: SqlBulkCopy - String To Type Decimal In Target Column Error?

Mar 26, 2010

I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:

"The given value of type String from the data source cannot be converted to type decimal of the specified target column."

Here is the StackTrace:

Data Controls :: GridView Export To Excel - Round Decimal Numbers To Two Decimal Places

May 7, 2015

I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.

I used:

xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";

And no works (h is for rows, N is the column. Into a foreach).

DataSource Controls :: Decimal Values Not Updating With Decimal Places?

It's trying to update a column which data type is set to decimal. Just so you know what I really need out of it, here is an example:

[Code]....

The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
