C# Math Abs(Int32)

Description

Math Abs(Int32) returns the absolute value of a 32-bit signed integer.

Syntax

Math.Abs(Int32) has the following syntax.

public static int Abs(
  int value
)

Parameters

Math.Abs(Int32) has the following parameters.

• value - A number that is greater than Int32.MinValue, but less than or equal to Int32.MaxValue.

Returns

Math.Abs(Int32) method returns A 32-bit signed integer, x, such that 0 d x d Int32.MaxValue.

Example

The following example uses the Abs(Int32) method to get the absolute value of a number of Int32 values.

/*from  w  w w  .jav  a 2s. com*/
using System;

public class Example
{
   public static void Main()
   {
      int[] values = { Int32.MaxValue, 12345, 0, -987658, Int32.MinValue };
      foreach (int value in values)
      {
         try {
            Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value));
         }   
         catch (OverflowException) {
            Console.WriteLine("Unable to calculate the absolute value of {0}.", 
                              value);
         }
      }
   }
}
