C＃十进制关键字 (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.

在C＃中， 十进制是一个关键字，用于声明一个变量，该变量可以存储介于±1.0 x 10 ^-28到±7.9228 x 10 ²⁸范围内的浮点型值(精度值)。 十进制关键字是System.Decimal的别名。

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

它在内存中占用16个字节(128位)。

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

注意：为了表示一个十进制值，我们使用m或M作为文字的后缀。

Syntax:

句法：

    decimal variable_name = value;

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

它可以存储介于±1.0 x 10 ^-28到±7.9228 x 10 ^{28之间的值} 。

C＃代码演示小数关键字的示例 (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.

在这里，我们声明一个十进制变量num ，使用值5610.2361m对其进行初始化，并打印其值，类型和十进制类型变量的大小。

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

输出量

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