Dim y as integer
dim x as double = 125 / 60
y = Convert.ToInt32(x) 'removes decimals
That method works, it removes all the numbers after the decimal.
But, how to check if the double contains a decimal and if it has it, remove all the numbers after it?
I have tested all the possible solutions i can think of, but I always run into a lot of errors

Tabpages: Using a button, how do I go from tabpage1 to tabpage2? I have it kind of sorted, only not: Button click tabpage1 send to back() or hide() tabpage2 show() The problem with this, is it does not actually turn the page, and the tabpage1 tab still shows at the top. Decimals: Epically basic, I guess. I have calculations that does, for example: 10/6 = 1.666666666667 How do I get it to say 1.667 only?
And Lastly, Graphs: I have a line graph. I have fixed series as a envelope for the variable series to sit in. Again, epically basic - How do I make a series that draws a line for a variable?

View 23 RepliesIf i wanted to know if a whole number is a multiple of 10 or not I know i can do for e.g
If VarWholeNumber MOD 10 = 1 Then
......
Endif
But if i have a whole number with format "0.00" how can i only check if the last 2 digits after the decimal is a mod of 10 regardless of what the whole number sides value is.
So something like
If VarWholeNumber's ".00" MOD 10 = 1 Then
.......
Endif
How could I could this?

i have three cells in a datagridview third cell gives the result of multiplying first and second cell.When i reload or populate this data from datatable into that datagridview value comes like 40.00. with two decimals. For example
58.00 -------->i need only 58
58.78--------->i need exact 58.78
The only problem is to remove the decimals if they are 0.

I've used .NET for a long time now but I have come across something I haven't had to do before and I'm struggling to work it out. What I need to do is work with binary numbers and convert them to decimals and vice versa but not necessarily using even numbers e.g. I would like to represent a number between 0 and 2047 which can be represented with 11 binary digits. Plus I want to represent a second number between 0 and 500000 which can be represented with 19 binary digits, and a third number, fourth etc. Then I want to string the whole binary results together and split it in to sections of lets say 5 bits each and convert those back to decimal.

View 8 RepliesHow to set default two decimals place in the textbox?
View 1 RepliesI have only started programming in VB recently and I am not very good on the coding side. I have two values a and b. When I divide them, I want only the integer part to show up ignoring all the decimals and storing it into the variable c.
i.e.:
a = 24, b = 11
c = 2
Output: 2
When i add it up it doesn't add decimals.

I'm having some difficulty formatting some of my strings, I can't see what's wrong unfortunately. I have various numbers, e.g. 100.023, 13488.323, etc in a datagridview column that I would like to be formatted so it looks like this: $123,456
Here's what I've tried so far (that isn't working):
row.Cells(1).Value = Format(row.Cells(1).Value, "{0:D0}") 'I've also tried using {0:C0}
row.Cells(1).Value = row.Cells(1).Value.ToString("$#,#")
'This one (above) comes up with an error saying it can't put an "##" in an Integer column, something like that anyway.

I'm having problem with our germany customers whose operating system uses dot as thousand separator and comma as decimal point.I have an application which reads some text from an Access database, parse it into data and display on a datagridview,the program also needs to write the data into another file as input to another application. right now, it seems when my application parses doubles (say 0.2500),germany os will always return everything except the decimal dot(so 0.2500 becomes 2500),and that just messed up the whole process...so my question is, how can we detect the locale of the windows and parse the doubles correctly?
