Two Decimal And Three Decimal Rounded Numeric Value
Dec 2, 2010
Maybe this is just a really basic question that everyone knows the answer to, and is why I couldn't find the answer. What I want to do is pretty simple. I want to declare a custom type that's just like a Single, except when you access the value, you get the value rounded to the second or third decimal place. Something like this:
Dim MyNumer as TwoDecimalNumber
MyNumer = 1.124
Msgbox(MyNumber) 'This would pop up a box showing "1.12"
[Code]....

I'm working on a calculator application and one function is to find midpoints on a cartesian coordinate system. I have inputs for two x and two y coordinates , and the program calculates the midpoints of both and prints them in a text box as a new set of coordinates. The points are represented by doubles to allow decimal and negative points, but I want to round the final coordinates to 1 decimal place. e.g: (12.5, 9.8) Math.Round would work, except that it only seems to be able to round to a whole number. e.g: (12, 10)
Is there any way to specify how many decimal places Math.Round rounds to, or is there another function that could acheive this result?

I have read about Round() and MidpointRounding.ToEven but I still could not figure how to use it to achieve what I want. I have numbers (usually from 5 digit decimal) such 125.36 , 125.10, 125.99. I want to make the 2 decimal point rounded to the nearest 20. Means, the 2 decimal point should be either .00 or .20 or 0.40 or .60 or 0.80 only.
125.36 should be 125.40 : 125.10 should be 125.00, 125.99 should be 126.00
125.54 should be 125.60 and so on
Is there math function to make or I should parse the number as text and test the last 2 digit?

Why my math keeps getting rounded to 0 decimal points by default?When I do this I get return value of 1
Private Sub Button4_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
Dim numb1 As Integer
numb1 = 100 / 78
MsgBox(numb1)
End Sub
How to get that value up to two decimal points (like 0.00)?

I have a bound Datagridview with a column Quantity in which I want to enter numbers but dont want the user to type a decimal. E.g. 100 should be allowed, however 100.23 should not be allowed.Have set the DefaultCellStyle property of this column to
DataGridViewCellStyle { Format=N0 }
AND
Also in my Form Load event i have entered below code:
Me.DataGridViewTblInvoiceDetailsAndTblTempInvoiceDetails.Columns(2).DefaultCellStyle.Format
= "N0"[code].....
However this is not working.When I run the program it is allowing me to enter decimal values.

it should take either decimal values or integers and max length is 16if it takes decimal value as input then it should contain only 14 digits in decimal place and 2 digits in fraction part eg(1234567.12-valid) but (12345678.123 - invalid) and also(123456.12345- invalid)

My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .

How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:
Variable 123.34D ----> textBox 123,34 or 123.34 -----> variable 123.34D

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..

I have a string which looks like this 512.3 is there a way to add a trailing zero so it looks like this 512.30 Just to clarify (sorry I didn't know there where different ways etc.) My string is an amount which is passed so changes all the time I only need the trailing zero on amounts like 512.3, 512.4,512.5 etc. as some of my amounts will pass values like 512.33 and 512.44 and so on

I am trying to convert information stored in a file to a decimal (or ASCII) format, then write the contents of that file to a new file.
What I have is a list of files that are generated from a cash register. The documentation that was provided to me says that this particular file I am trying to work with has a length of 6, a width of 6, and that it's BCD type.
I've done quite a few google searches and can't seem to find a good solution. I know BCD numbers should be stored as 0000 format. But the problem I'm getting is when I read each part of the file (using my sr.read) I'm getting full numbers..and I am expecting the 0000 format. I'll get a 0, 0, 0, and then all of the sudden I"ll get a number that's 65,000..then I'll get a 34...and there doesn't seem to be any
I'm sure I'm doing something incorrect here, my knowledge of reading HEX, BCD, etc. is very minimal. I'm guessing it has to do with using a filestream, so I can use the fs.ReadByte() method..but when I tried that my program was literally chugging along for several minutes with no sign of ending.[code]...

Using Visual Studio I'm using TextRange processing a word at a time, parsing for figures and minus values etc. All of which works. 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.
