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?
I'm creating a maths program and when it comes to division it's giving me .34216 as answeres which isn't what I want.I was thinking declaring the textbox the answer appears in as a single.It's not working out though and it's still using decimal points.I was told by my teacher to declare it as an integer so I tried that too, it's not working out also. I figured based on the code, I would be declaring array3() as the single or integer since that's the textbox the answer will be output into. [code]
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
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"
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 use Mschart to produce charts. What I am trying to get is the nearest data point by where I click on the chart. The problem is that I can't find any connection between the HitTest values and the data point x/y values.Say, I clicked on the following point:
Dim result As HitTestResult = Chart.HitTest(e.X, e.Y)I have now values of X and Y where I clicked. How to associate it with the data point values?
What I want to achieve is to double-click on the chart which would find the nearest data point (x,y as integer) and knowing these values I would be able to recalculate other values based upon where the user needs it and double-clicks.
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 value that shows a integer value between 0-100. For a little math, I need to be able to add a decimal in front of the value. So if the value was 50%, I need it really to be .50%.
I am trying to move some data from an Excell sheet to an AS/400 file.
I have my app working, in that, the data is getting to the correct table, but the problem I'm having is that one of the columns in the spreadsheet contains numbers ie; 1234.55
I need to get that to the AS/400 as 123455 in a text field.
Currently I am moving the data from one dataset to another as follows.
I think what I need to do is seperate the whole number from the decimal and then concatenate the values. ?Not sure how to.
Also, some of the values in the spreadsheet may end in a zero such as 1234.50 but only show the 1234.5 so even fnding the decimal and then taking the next two characters won't always be correct.
I was wondering how i can get as far as the second point in a Double. I have a double that will contain a number such as 12.98 but when i try to show it in a textbox it shows as 12.98000000000000000 I know this is because its double but im unsure about to to retrive only as far as the .98 and get rid of all the 00000000000000
How to add decimal point (with two decimal places) to string, without converting string to decimal? For example (Dim str1 as String), regardless str1 has value: 100 , 100.0 , 100.00, or 100.5 , 100.50..I'd like to get the output: 100.00 or 100.50, with two decimal places.
Basically in my in my aspx page I have a gridview which displays the value from my database as an image. So if a value in my database table is 5, it will be displayed as 5 images in the gridview. ie.(star.jpg star.jpg star.jpg star.jpg star.jpg)The code:
Protected Function getrating(ByVal rate As Integer) Dim getrating As String getrating = ""
For some time I try to get the comma instead of the decimal point, but the labels I use won't display a comma. For some reason I don't understand, the msgbox() does the trick, but is useless in my application. This is my last desperate piece of code I tried but it also failed.
Expresserprijs = EuropluscolNL(ArrayCol, 2) - EuropluscolNL(ArrayCol, 1) ' All above are "Doubles" and are fed with data like 21,45 (with comma's that is) Decimaalteken = Expresserprijs ' Decimaalteken is a string MsgBox(Decimaalteken) [Code] .....
I'm making a sciene program so I want to draw the graphic with decimal size and location. But the parameters are always integer, not decimal or double. Can I do that?What is big but light?
I am trying to think of a possible way to insert a colon and decimal point to a part of a number. I am making a Rubik's Cube timer, and I converted the times to milliseconds so I can calculate the average of 5 with that. I averaged the milliseconds, but now I need to convert that into minutes, seconds, and milliseconds. Does anyone have any idea on how I would go about this?
I got this class from another vb help forum and I'm using it for fields that accepts monetary values. Is there a way to incorporate a '1-decimal' point only rule?ATM, I can enter values like this: 1.2.2.20000..I need to limit the number of decimal points used. (1.0000)[code]
I want to specify the user to enter only the numbers and decimal point in the text box.[code]values something like that which contain only numbers and dot.This is the code to enter the numbers only.[code]How to make the code to accept dot also?
I create a calculator in visual basic and I put button from 0 to 9 ... and event click textbox1.text = textbox1 + "1" (to 9) ..it work good .. but if i press key 0 from keybord nothing is hapens ..
and the secoun problem .. if I put for example 3.25.89 not 3.2589 how can write in code a "if" for example if textbox1.text -alredy contain a point (.) 3.25 then I click again on button point .. it remain 3.25 but not 3.25.
I'm drawing polygons,lines,etc. and I have to have the points of each precise - up to 12 decimals. Since a Point only takes integer values, I'm not sure how to handle scaling. I have a working user control, but rounding the decimals so I can put them into points is causing incorrect calculations (area, ect.).
