C#中的Decimal.Round()方法
C#中的Decimal.Round()方法用于将值舍入到最接近的整数或指定的小数位数。
语法
以下是语法-
public static decimal Round (decimal d); public static decimal Round (decimal d, int decimals); public static decimal Round (decimal d, MidpointRounding mode); public static decimal Round (decimal d, int decimals, MidpointRounding mode);
示例
现在让我们看一个实现Decimal.Round()方法的示例-
using System;
public class Demo {
public static void Main(){
Decimal val1 = 9.00m;
Decimal val2 = 15.29m;
Decimal val3 = 394949845.14245M;
Console.WriteLine("Decimal 1 = "+val1);
Console.WriteLine("Decimal 2 = "+val2);
Console.WriteLine("Decimal 2 = "+val2);
Console.WriteLine("Remainder = "+(Decimal.Remainder(val1,val2)));
Console.WriteLine("Value 1 (Rounded) = "+(Decimal.Round(val1)));
Console.WriteLine("Value 2 (Rounded) = "+(Decimal.Round(val2)));
Console.WriteLine("Value 3 (Rounded) = "+(Decimal.Round(val3)));
}
}输出结果
这将产生以下输出-
Decimal 1 = 9.00 Decimal 2 = 15.29 Decimal 2 = 15.29 Remainder = 9.00 Value 1 (Rounded) = 9 Value 2 (Rounded) = 15 Value 3 (Rounded) = 394949845
示例
现在让我们来看另一个实现Decimal.Round()方法的示例-
using System;
public class Demo {
public static void Main(){
Decimal val1 = 6.59m;
Decimal val2 = 30.12m;
Decimal val3 = 6946649845.25245M;
Console.WriteLine("Decimal 1 = "+val1);
Console.WriteLine("Decimal 2 = "+val2);
Console.WriteLine("Decimal 2 = "+val2);
Console.WriteLine("Remainder = "+(Decimal.Remainder(val1,val2)));
Console.WriteLine("Value 1 (Rounded) = "+(Decimal.Round(val1,1)));
Console.WriteLine("Value 2 (Rounded) = "+(Decimal.Round(val2,1)));
Console.WriteLine("Value 3 (Rounded) = "+(Decimal.Round(val3,2)));
}
}输出结果
这将产生以下输出-
Decimal 1 = 6.59 Decimal 2 = 30.12 Decimal 2 = 30.12 Remainder = 6.59 Value 1 (Rounded) = 6.6 Value 2 (Rounded) = 30.1 Value 3 (Rounded) = 6946649845.25
