How can I join more than one integer number to become one integer (Long) number?
e.g. 2, 3, 2 and 5 = 2325
123, 7 and 2 = 12372
10, 0, 5 and 1860 = 10051860
0, 10 and 450 = 10450
How could i round an integer number based on the last digit of the number?
For example:
Dim x As Integer = 12
Dim y As Integer = 139
Dim z As Integer = 2322

I've just begun using VB2008 Express. As practice, I'm trying to create a simple program that allows users to practice their basic arithmetic skills. I've just run into one hiccup.
I have a procedure that generates random numbers for the program to spit out as text that the user will then do arithmetic on. I'm trying to create a loop that checks, in the case that a radio button selecting division practice, that the potential quotient [code]...
What i'm trying to do is compute whether an integer number is prime or not. The program performs this analysis for all odd numbers from 3 up to an input integer limit, for example 100. If the integer in the range 3 to limit is prime, a message stating so is printed. Otherwise, a message is printed that lists at least one other integer divisor. The output for each analyzed number consumes one line of text.
A sample output is shown below:
Limit is 100:
Number 3: is prime
Number 5: is prime
Number 7: is prime
[CODE]...
I understand I need to use loops, boolean functions, vbmath(), strings and multi-line out via concatenation. So I can put this is words how I think it should be done but not so great putting the code together
Test all integers up to the SQRT of the number (100)
limit = math.sqrt(100) + 1
Followed by 1 For statement
For c = 0 to 100 step 2?
And an If statement
If ......
result = false

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
Is there a way of testing to see if a number variable is an integer, or a decimal?

I have designed a form with textboxes for numerical entry. I need to validate each textbox so the number entered is an integer, and is between 0-1000. I am struggling to find how to validate the data entry.
View 4 RepliesI have a program that will round any numbers I give it regardless of the data type I set (I've tried double and decimal) before it saves into the DB. I'm using MS access for the DB and I've set the data types in access to Numeric Double, Numeric Decimal, and Currency and all with decimal places set to 4 -- all to no avail.
What I do know:
1) The textboxes on the form accept the number value as I enter it and after I hit save the value displayed is the same as the number that I entered. However, once I query the database again for that entry the value has been rounded up/down to the nearest integer (whole number). For example: I enter 1000.50 and hit save. I search for that same entry and the value is saved as 1000. If I enter 1000.51 and hit save then search for the entry it shows the value saved as 1001.
2) I can store the desired value directly into the DB by manually entering it. When I search for that entry from within the program it displays the correct amount. HOWEVER, if I try to change the amount and then hit save I get a concurrency violation.
I think that it may be a setting somewhere in the program that doesn't allow for decimal places but I've search everywhere and I cant find anything.

What is the reason for the error I get?
I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
