How to find absolute number of a given number in c# programming

7:58 AMWednesday, February 26, 2014
In c# programming we easily find absolute number of a given number. We can use Abs function, which is include in Math class. Lets take an simple example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            sbyte sortbyte1 = -12, sortbyte2 = 12;
            short shnumber1 = -13, shnumber2 = 13;
            int integer1 = -14, integer2 = 14;
            long long1 = -15, long2 = 15;
            float float1 = -16.0f, float2 = 16.0f;
            double double1 = -17.1, double2 = 17.1;
            Decimal decimal1 = -18.0m, decimal2 = 18.0m;

            Console.WriteLine();
            Console.WriteLine("SortByte:   1) {0,-2} {1,-2}", Math.Abs(sortbyte1), Math.Abs(sortbyte2));

            Console.WriteLine("Integer 16 bit:   1) {0,-2} 2) {1,-2}", Math.Abs(shnumber1), Math.Abs(shnumber2));

            Console.WriteLine("Integer 32 bit:   1) {0,-2} 2) {1,-2}", Math.Abs(integer1), Math.Abs(integer2));

            Console.WriteLine("Integer 64 bit:   1) {0,-2} 2) {1,-2}", Math.Abs(long1), Math.Abs(long2));

            Console.WriteLine("Single:  1) {0,-2} 2) {1,-2}", Math.Abs(float1), Math.Abs(float2));

            Console.WriteLine("Double:  1) {0,-2} 2) {1,-2}", Math.Abs(double1), Math.Abs(double2));

            Console.WriteLine("Decimal: 1) {0,-2} 2) {1,-2}", Math.Abs(decimal1), Math.Abs(decimal2));

            Console.ReadKey();

        }
    }
}
Here Math class provide Abs static method for returning absolute value of a given number. Abs function is overloaded by some data types like double, decimal, Int16, Int32 and SByte.
Code generate the following output
