C# Math Abs(Int64)

Description

Math Abs(Int64) returns the absolute value of a 64-bit signed integer.

Syntax

Math.Abs(Int64) has the following syntax.

public static long Abs(
  long value
)

Parameters

Math.Abs(Int64) has the following parameters.

• value - A number that is greater than Int64.MinValue, but less than or equal to Int64.MaxValue.

Returns

Math.Abs(Int64) method returns A 64-bit signed integer, x, such that 0 d x d Int64.MaxValue.

Example

The following example uses the Abs(Int64) method to get the absolute value of a number of Int64 values.

/*w  w  w .  jav  a 2  s  . c o m*/
using System;

public class Example
{
   public static void Main()
   {
      long[] values = { Int64.MaxValue, 112345, 0, -6876543, Int64.MinValue };
      foreach (long 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);
         }
      }
   }
}
