Limit Double At Six Decimal Place?
Mar 4, 2010i have a double, the decimal place isn't fix (8-?) i want to fix the decimal place to six (for example: 1,234567). this is my double:
CStr(score)
i have a double, the decimal place isn't fix (8-?) i want to fix the decimal place to six (for example: 1,234567). this is my double:
CStr(score)
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.
The biggest difference between double and decimal is that double is a floating point variable type whereas decimal is a fixed point variable .What it means?? Please Explain the abovePoint with Example.According to me both are used to store the folating numbers,then whats the difference between two?
View 1 Repliesi am working on a product based website in which i have a product table with product names and prices, i have defined the datatype of price as "Money"
but the problem is it shows price upto 4 decimals everytime, how i can limit that upto 2 decimals only, on the webpage as well as in the table also in database ?
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?).

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?
I am displaying a money values in a gridview. Is possible to use inline code to set the decimal places to two? Would like to do it inline instead of in the C# code behind if possible. Database table column [Rate] is datatype money.
GridView1. . . . .

<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# " total monthly " + "$" + Eval("Rate") %>' ></asp:Label>
</ItemTemplate>
</asp:TemplateField>

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).

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?
Some values are returning 2.0 but I need it to be 2.00 as this is a money value that is displayed to the web page.
I am doing:
Math.Round(value, 2);
Is there a way to force it to 2 numbers after the decimal?
I need a validation regex for decimal. It should allow upto 5 digits after decimal.
Allow:
1
1.0
12.0
12.01
123.01
1,123.01
1,123.013
21,123.01234
3,21,123.01234
How Can I do regex for this?
I have set Private Memory limit of 200mb in IIS 7 for an application pool. The Private Working Set memory(Task Manager) for the application is always below 125mb but the number of page faults have increased a lot and application cache is getting cleared frequently after setting the limit.
I haven't set any limit on Virtual Memory.why the cache is getting cleared even when the Private memory used is below the allocated memory?
I got a decimal member in my viewmodel and get populated from the database (say 55.5, or 100.00)
In my view I use TextBoxFor<> for this member.
Is there any way to have a number (it's actually a percentage) like 100.00 display as 100 instead, and 55.50 as 55.5?
I want to place two datalist controls at the same (x,y) position. When the first is visible, second should be invisible.
How would I go about implementing this?
int Def[0] = {6};
iMaxValue = 55;
decimal val = Decimal.Round(Convert.ToDecimal((DefCount[I]) / iMaxValue),3);
here if i try to run this it says answer 0 ; but if i want 0.1090
I'm using linq to sql,everything seems to be working fine except one thing,I'm showing any mapped float fields from my db tables as "Double?" instead of "Double", and when binding to a datagrid, any of those "Double?"fields don't show.If I iterate through the items and spit out the property,the float value is indeed there and properly returned.
View 3 RepliesI have problem in rounding the double value from 1.5 to 1.50. However I have tried different ways converting to decimal, Integer and also string.Format, still I gettting 1.5 instead of 1.50.
Variable will have value as 1.5 and expected output will expect 1.50 not 1.5. I am not able to get 1.50 as value.

Since both are acceptable by HTML as well as languages like ASP.NET and PHP when using attributes or strings, why is it that some people use single quotes and double quotes interchangeably? It is my understanding that it is syntactically correct to use double quotes where possible, single when you need to embed a double quote for inline logic. Is there something I am missing? For examples: HTML
<a href='[URL]
PHP
<? echo 'Hello World!'; ?>
ASP.NET
<form id='myForm' runat='server'></form>
I have all my errors handling up and going but now I wish to change the error messages that they display for empty integers.I have been going through my codes but I can't to change that. For now, the error message for all numeric values are "A values is required" and I wish to change it to "<TextBoxName> cannot be empty".
