C# Divide By Zero Infinity
in an if statement and only run that code when x.Amount > 0 ? –Adam Apr 20 '12 at 9:18 1 I think you should wonder why do you have items with 0 Amount :P –Adrian Iftode Apr 20 '12 at 9:20 1 In what business is Amount - Price a meaningful quantity? –Henk Holterman Apr 20 '12 at 9:36 @Adrian Iftode, this field can be set to 0 –Mediator Apr 20 '12 at 9:57 | show 1 more comment 2 Answers 2 active oldest votes up vote 10 down vote accepted ads = ads.Where(x => x.Amount != 0 && (x.Amount - x.Price) / (x.Amount / 100) >= filter.Persent); share|improve this answer answered Apr 20 '12 at 9:18 Jon 272k40477596 x.Amount > 0 seems just a tad safer. –Henk Holterman Apr 20 '12 at 9:37 it certainly would not help –Mediator Apr 20 '12 at 9:55 1 @simplydenis: What would not help? –Jon Apr 20 '12 at 10:00 1 @simple denis why wouldn't it help? do you need to include items with amout == 0? in that case what should D be in (-x.Price / D) >= filter.Persent (btw shouldn't that be percent as in %?) –Rune FS Apr 20 '12 at 10:01 1 @simplydenis: What error?

DivideByZeroException: This class is used to handle the exception which occurs when a number is divided by a zero. To handle this exception .net provides us a class named DivideByZeroException. DivideByZeroException Handling: We can handle divide by zero exception by writing try catch statement and passing DivideByZeroException object. To demonstrate make a window application. Drag one button and two text boxes on form. Enter values in text boxes and press button. Now write the following code on Button click event: C# private void btn_divide_Click(object sender, EventArgs e) { int a =Convert.ToInt16(textBox1.Text); int b = Convert.ToInt16(textBox2.Text); try { int sum=a/b; MessageBox.Show(sum.ToString()); } catch (DivideByZeroExcept
the "exception" to the normal, or expected behavior. Examples of exceptions that can occur in a program are: Disk Full / Drive Error Invalid Argument passed to Method (i.e. Empty array) Divide By Zero Exception Handling allows your program to do deal with exceptional events gracefully. When an exception occurs, you can choose to notify the user, or not. You may be able to recover from the error and let your program continue, or notify the user, and exit the program gracefully. In the days prior to exception handling, software programs required a great deal of coding to anticipate and handle exceptions. Error handling can easily create as much code as the functional part of the program just to handle the occasional error. Exception handling provides a much easier method for the programmer to handle errors. Overview Exception handling abstracts error handling from main programming task. When an error occurs, C# will "throw" an exception. You, the programmer need to "catch" the exception to handle the error appropriately. You can choose how you handle an exception by writing code that executes only when an exception occurs. You can also choose which exceptions you want to handle. All of them, or only selected exception types. The following is a simple exception handling example of a divide by zero exception written in a console application. static void Main(string[] args) { Console.WriteLine("Enter numerator:"); int numerator = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Enter denominator"); int denominator = Convert.ToInt32(Console.ReadLine()); int result = numerator / denominator; Console.WriteLine("\nResult: {0:D} / {1:D} = {2:D}", numerator, denominator, result); } This program works great, displaying the integer result from dividing two integers. But what happens if the user enters 0 for the denominator? This error pops up in our code. It is an exception of type DivideByZeroException. Now let's see how we can use exception handling to handle this error. static void Main(string[] args) { Console.WriteLine("Enter numerator:"); int numerator = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Enter denominator"); int denominator = Convert.ToInt32(Console.ReadLine()); try { int result = numerator / denominator; Console.WriteLine("\nResult: {0:D} / {1:D} = {2:D}", numerator, denominator, result); } catch (DivideByZeroException ex) { Console.WriteLine("Can't divide by zero"); } } Notice the only
