关于Math.Exp()

Question

const int months = 12;//定义常量months
            const int weeks = 52;
            const int days = 365;
            //可以使用定义过的常量声明新的常量
            const double daysPerWeek = (double)days / (double)weeks;   //定义常量daysPerWeek
            const double daysPerMonth = (double)days / (double)months;
            var flag = true;
            var name = "Tom";
            var annualSalary = 500000;
            var monthSalary = annualSalary / months;
            var weekSalary = annualSalary / weeks;
            var daySalary = annualSalary / days;
            //var x = Math.Exp(2);                                               这一行好像有没有结果都一样！
            var y = name.Length;
            Console.WriteLine("double型常量daysPerWeek的值是：{0}",y);
            Console.WriteLine("常量变量的演示结果：");
            Console.WriteLine("double型常量 daysPerWeek的值是：{0}",daysPerWeek);
            Console.WriteLine("double型常量 daysPerMonth的值是：{0}", daysPerMonth);
            Console.WriteLine("匿名变量flag的值是:{0}", flag);
            Console.WriteLine("匿名变量monthSalary的值是：{0}", monthSalary);
            Console.WriteLine("{0}的年薪是:{1}元", name, annualSalary);
            Console.WriteLine("{0}的月薪是:{1}元", name, monthSalary);
            Console.WriteLine("{0}的周薪是:{1}元", name, weekSalary);
            Console.WriteLine("{0}的日薪是:{1}元", name, daySalary);
            Console.ReadKey();
请问Math.Exp(）的功能是什么啊？求独创详解！而不是微软上的那个！

1楼和2楼是对的，通俗一点讲，就是e^X，就是x个e相乘……
