C#Math的一些函数用法

using System;
using System.Collections;
using System.Collections.Generic;
using System.Net;
using System.IO;
using System.Text;
using System.Drawing;
using System.Text.RegularExpressions;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
double totalPrice = Math.Floor(10.9);
Console.WriteLine(totalPrice);//返回10
double totalNumber = Math.Truncate(0.7);//获取整数部分
totalNumber = Math.Round(10.4);//Round的作用就是四舍五入,让其最接近整数部分
Console.WriteLine(totalNumber);//返回10
totalNumber = Math.Round(10.6);//返回11
Console.WriteLine(totalNumber);
Console.ReadLine();
}

}
