C# decimal keyword

In C#, decimal is a keyword which is used to declare a variable that can store a floating type value (value with the precision) between the range of ±1.0 x 10-28 to ±7.9228 x 1028. decimal keyword is an alias of System.Decimal.

It occupies 16 bytes (128 bits) in the memory.

Note: To represent a decimal value, we use m or M as a suffix with the literal.

Syntax:

    decimal variable_name = value;

It can store the value between the range of ±1.0 x 10-28 to ±7.9228 x 1028.

C# code to demonstrate example of decimal keyword

Here, we are declaring a decimal variable num, initializing it with the value 5610.2361m and printing its value, type and size of a decimal type variable.

using System;
using System.Text;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            //char variable declaration
            decimal num = 5610.2361m;

            //printing value
            Console.WriteLine("num: " + num);
            //printing type of variable
            Console.WriteLine("Type of num: " + num.GetType());
            //printing size of a decimal 
            Console.WriteLine("Size of a decimal variable: " + sizeof(decimal));

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

num: 5610.2361
Type of num: System.Decimal
Size of a decimal variable: 16
