How can i format a double number to be like a integer?
for example:
i want to 12.34 to be rounded and displayed like 12 not 12.0.
because when i do String.Format("{0:n0}", 12.34) the number will be displayed as 12.0
The problem i m facing is that i m getting all numbers in this format
1- if it is double then 123.45
2- if it is integer then 123.00 which is wrong
how to format a number wether it is in decimal or integer.if it is decimal then something like 123.56 or if it is integer then 123 not 123.00.Tell me the generalized string function and how to use it..

View 4 RepliesI'm trying to write a (WPF) program with Option Strict on, but I have a problem.
I have a Canvas with a background image, and I want to use the coordinates of where the canvas was clicked to determine what should happen next. (Something like this)
Dim p As Point = e.GetPosition(DirectCast(sender, Canvas))
Dim imgColorMap As System.Drawing.Bitmap = My.Resources.ColorMap
Dim c As System.Drawing.Color = imgColorMap.GetPixel(p.X, p.Y)
This gives me the error: "Option Strict disallows implicit conversion of 'Double' to 'Integer'" for p.X and p.Y I have tried several things, like Math.Round but strangely enough that also returns a double.
How do I cast/round these Double values to Integer, so I can use them in my GetPixel method?
I am making a simple timer but I seem to be having some troubles formatting the time. What I have done is split up the hours, minutes, and seconds into integers. The problem is, I do not want my minutes and seconds to be 1:1 for 1 minute and 1 second. Instead I would like it to be formatted mm:ss.What command is used to format and integer to add a preceding 0 or not?

I am making a program that shows a data of azimuth and elevation of a radar. Example:
Azimuth = 203.40

View 3 RepliesI would like to cast a double to an integer, but rather than keep the numerical value the same I want to keep the bit pattern the same (this is for a compression algorithm), is this already possible in VB.net, or would I need to try and come up with my own method for doing this?

View 3 RepliesSo, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))
Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.
I'm trying to get my chart (y values) updated on the run, they need to be updated by an integer.
Dim a As Integer
Dim b As Integer
'some button.click code, contains a += 1 and b += 1
Chart1.Series("Series1").Points(0).YValues = a
Chart1.Series("Series1").Points(1).YValues = b
But it says Value of type 'Integer' cannot be converted to '1-dimensional array of Double'.
so, what do I have to do to fix this?

I'm quite a newbie in VB.NET (and VB on the whole). So my question could sound rather odd, but still. I've stumbled upon an issue with the CInt and converting a double to an integer.
The issue is the following: CInt(10.5) would be 10
CInt(10.51) would be 11, but I expected 10... (Got used to C# style conversion: (int)10.51 would be 10)
As pointed out here Integer.Parse VS. CInt the result is just rounded in some fashion. Nowever, all I need is to get only integer part and throw away the fractional one. How can I achieve such type of conversion in VB.NET? After a short research I assume that I can use Fix() funciton to do the trick, but is it the best choice ever?
