Format Decimal Number (Comma As Fraction Separator With Two Digits)

May 22, 2012

Is there a format string to format a decimal to 000000000,00. So first 9 digits, right padded with zeros if needed; a comma as fraction separator and two fraction digits.
0 => 00000000,00
12 => 00000012,00
987456,456 => 000987456,46
So something like myDecimal.ToString("D9") together with .ToString("F2").

When Adding A Value To Another Value The Results Eventually Change From 2-decimal Places To Multiple Decimal Places?

Mar 13, 2009

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.

Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54

[code]....

As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..

txt_Alt_Press.Text = Strat_Press.ToString(Press_DP)

I then set Press_DP in a module, declared as a public variable,

Public Press_DP As String = ("F1")

So what I want to do is make the "F1" bit a variable in itself, so then the user can set the number of decimal places with a numeric up-down control.

Detect Culture Of Number Period Or Comma For Decimal Point / Thousands Separator?

Jul 1, 2011

In VB.Net, is there a way of auto-detecting the culture of a string representation of a number? I'll explain the situation:Our asp.net web site receives xml data feeds for boat data. Most of the time, the number format for the prices use either a simple non-formatted integer e.g. "999000". That's easy for us to process.Occaisionally, there are commas for thousands separators and periods for the decimal point. Also, that's fine as our data import understands this. Example "999,000.00".We're starting to get some data from France where some of the prices have been entered with the periods and thousands separators the other way around as that's the way it's done in many European countries. E.g. "999.000,00". This is where our system would interpret that as nine hundred and ninety nine pounds instead of the nine hundred and ninety nine thousand pounds that was intended.

Display The Number With Two Decimal Places And Dollar Signs?

May 7, 2009

I need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.The summary menu item displays a message box that holds total sales,total commission,and total pay for all salesperson. Display the number with two decimal places and dollar signs. the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.The Color and Font menu items should change the color and font of the information displayed in the total pay text box.Use a message box to display the program name and your name as programmer for the about option on the Help menu.

[code]...

So the issue is when I push the pay/calculate button everything is calculating correctly the first time, but then when I push clear to input another workers name and weekly sales and push calculate, my label is blank and does not display any info about the second worker. Then when I push summary after inputting the second worker, it's only displaying the total calculations of the first worker. I can't seem to figure out this problem on my own (After countless hours staring at my code I might add!), so I am hoping somebody can pinpoint what I have done wrong? EVerything else is seeming to work just fine.[code]...

Filter Xml Using Xpath And Linq (price With Decimal Separator And Thousands Separator Spanish)?

Jun 7, 2012

I'm trying to filter the results of a xml file. One of the fields I've been requested to filter is the attribute price of each node. The problem is the xml is from a spanish source and the prices are with decimal separator being , instead of . and thousands separator is , instead of .I'm trying to get an xml file filtered where only nodes withprices lower than one supplied appear.

The xml structure is:

<RoomStays>
<RoomStay InfoSource="" Price="201,60" Discount="0" MealPlan="Sólo alojamiento" MealPlanId="1" Provider="Marsol" ProviderId="3" HotelName="HOTEL LA ESTACION" Rating="" Latitud="" Longitud="">

[code]....

I've tried to filter using XPath and Linq2Xml. I've come to the conclussion I have to replace , with . and . with , but I get 0 results.With values below 1000 where there is only , I've got it using:

doc.XPathSelectElements(./RoomStays/RoomStay[translate(@Price,',','.')<=256.78])

But when there are prices above 1000 with thousands separator . it doesn't work, so I tried:

doc.XPathSelectElements(./RoomStays/RoomStay[translate(translate(@Price,'.',''),',','.')<=256.78])

But it returns 0 results (I tried to use replace function instead of translate to remove the . characters but I get an exception).

Convert String To Integer With Variable Decimal Sign?

Nov 22, 2011

I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.

At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.

The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

Datatype Mismatch Due To Decimal Separator?

May 14, 2008

The code works perfectely when the regional settings are default US-EN.For computers running in germany an update to the backend database throw a datatype mismatch error. I change the decimal separator on the computer with 'German' for region settings from Comma (,) to (.) period and everything works fine.I add thread culture to US-ENG at the startup of the application. Now the error disappears but then 2.5 is now stored as 25 in the access database.

I add these lines at the beginning of the application soon after the designer code

System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("en-US") System.Threading.Thread.CurrentThread.CurrentUICulture = New System.Globalization.CultureInfo("en-US")

How To Mix Decimal Places

However I have to honour the original number of decimal places in the figures, even though they may be 0's.ie -1219.0 and 1219.00 are both valid inputs the valid outputs would be(1,219.0) and 1,219.00, I can't just use tostring and stamp all of them as "N2" etc).I have to format including retaining the trailing 0 if necessary.I can use "#,##0.######" but that removes trailing 0's... ie both above example would be changed to 1,219 pos or neg.

Estimating π To >14 Decimal Places?

Oct 30, 2010

My computing teacher challenged me to write a console program in Visual Basic.NET which would calculate π, AKA Pi, to 14 decimal places. I contemplated various algorithms, then settled for a variant of Leibniz's series which would converge rapidly whilst being simple to implement.After about 30 minutes or so of programming I had finished my program which could generate the first 14 decimal places of π in a mere 27 iterations, below is the source code:

[Code]...

However, to my dismay, I soon discovered that this was all my program was capable of because of the IEEE specifications for numbers, although I've heard of people generating π to thousands of decimal places using unmodified Personal Computers so if you could tell me how I should modify my code to work around this to generate say 500 more decimal places.
