Converting Double To String (Not In Scientific Notation)
Nov 12, 2011The only post I can find on this matter is one that coverts the double to a decimal before converting it into a string. However the numbers I'm using are far larger than what a decimal can store.
Example: 1/(16^10)
So how can I convert the solution to the problem above. Which equals 0.00000000000090949470177292824, to a string value that is exactly as it's shown?
Cause when I convert this to a decimal I still end up with a string in scientific notation..
EXCEL Reads A Text String As Scientific Notation
Dec 31, 2007I am working on a project that involes reading an Excel file, picking through it, then creating a flat CSV file. One of the the data elements I am picking up is a 9 character string that may be numeric, or contain one or more alpha chatacters. Excel has a nasty habit of converting long numerics to scientific notaion. I can overcome this by converting the "general" string to "TEXT".
However, there is one instance where I can not get the function to work...the string is "90333E108" ( the CUSIP for USU). Regardless, the text string is saved properly into the CSV file. When opened in a text editor, it reads correctly.
When opened with Excel, it is in scientific notation. Changing the field to "text" from "scientific" still displays "9.03E+112".
how to create an csv file that Excel will open and read correctly?
You can test this by creating an Excel workbook, format all cells as TEXT and add the following data:
90333E108

Prevent Data From Displaying In Scientific Format?

Scientific Calculator - Clear Textbox After Displaying Result
Jun 2, 2009I am building a scientific calculator.
1. After I clicked the Sine button, I get the result in a textbox.. When the result is there, for example: 1 radians Sine = 0.8414.... I can still put numbers at the end of this result.. like button 5 will be 0.84145, so how can I disable that?
2. After I get the result from a calculation, the textbox should be cleared when I insert a new number.
Asp.net - Prevent Numbers From Showing In Exponent Notation?
Oct 21, 2009I've got an app that sometimes stores some decently small numbers, such as 0.000023425. These numbers get loaded up in TextBox controls for users to edit.
Dim number As Double = 0.000023425
someTextBox.Text = number.ToString() ' Shows "2.3425E-05"
As mentioned, the text that shows is 2.3425E-05, which isn't exactly intuitive for the user to see, plus I have numbers even more precise (out to 19 decimal places). I would like the output to be fixed point. Of course I could easily and cleanly do:
number.ToString("F20") ' Shows "0.00002342500000000000"
But then there's an annoying number of zeros left over. So, to fix that, I could do:
number.ToString("#,##0.####################") ' Shows "0.000023425"
Which is what I want, but is there any better way to do it than to have that giant ugly format string there? So, ok, it's not that ugly, but surely there's a different way, right? My goal is to show the raw value being stored in the DB in a friendly way, and I would rather not have to force a format on the number at all.I found that changing the underlying datatype to Decimal solves the issue.
Dim number As Decimal = 0.000023425
someTextBox.Text = number.ToString() ' Shows "0.000023425" instead of "2.3425E-05"
So it sounds like Doubles aren't precise enough to be displayed normally?

VS 02/03 Use A Double Dot Notation Instead Of The Single Dot Notation?
Apr 11, 2009I am trying to have a firm grasp of VB.NET and wondering if there is a way to use a double dot notation instead of the single dot notation people are normally accustomed to?The double dot notation that I want to implement is shown directly below:
PersonData.Birthdate.IsValid
Currently, the only way I know is by using the call shown below which I suspect is not using the full capabilities of .NET:
Validations.IsValid(PersonData.Birthdate)
My code is shown below:
vb.net

Write Double In Non-scientific Form?
Sep 18, 2009I would like to know if Visual Studio does have a setting where you can choose whether it should write nombers like 0.00000127 in scientific notation or not? I am writing such doubles to file but VB2008 writes them in scientific notation. If I treat these numbers as decimals then it writes them correctly, but I also have to take care of performance as I'm writing lots of numbers.

View 3 RepliesShow A Textbox Displaying Numbers With A Control?
Jun 20, 2011I have three Buttons labled "Single" "Double" and "Triple" and four textboxes, one for each button and one to display the results. Here is how it works. Each time I click on one of the buttons, it increments itself by that number...for example if I click on Button with the word "Triple" on it I will get the result '3' in the adjoining textbox. If I click it again the number will change to '6'. This holds true for all the buttons. I have this part of the program working well. there a way to have the addition of all these numbers appear in the fourth textbox WITHOUT having to use another button. In other words I want the fourth textbox to constantly update as I'm pushing buttons.

Forms :: Checked=True For Any Radio Button Form Loads?
Jul 4, 2011My form has four panels, each contains radio buttons. At design time, all buttons have checked = false, which is what I want when form loads.When the form loads a radio button in one panel has checked = true
For the other three panels, all radio buttons have checked = false.I have tested this with no code in the Form_load subrroutine.How is checked = true being set for that that one radio button ?
Does The IDE somehow force at least one radio button on the form to have checked = true?
Can I force checked = false for all radio buttons when the form loads? If so, how?
