在C#中使用pragma intrinsic(sqrt,pow)？

using System;

class Program
{
    static void Main()
    {
        double x = 9.0;
        double y = 2.0;

        // 使用内部函数计算平方根
        double sqrtResult = Math.Sqrt(x);
        Console.WriteLine("Square root of {0} is {1}", x, sqrtResult);

        // 使用内部函数计算幂运算
        double powResult = Math.Pow(x, y);
        Console.WriteLine("{0} raised to power of {1} is {2}", x, y, powResult);
    }
}
