是否有一个用于长类型的函数 Math.Pow(A,n) ？

我正在测试一个小的 C# 程序片段：

        short min_short = (short)(int)-Math.Pow(2,15);   
        short max_short = (short)(int)(Math.Pow(2, 15) - 1);
        Console.WriteLine("The min of short is:{0};\tThe max of short is:{1}", min_short, max_short);

        int min_int = (int)-Math.Pow(2, 31);
        int max_int = (int)(Math.Pow(2, 31) - 1);
        Console.WriteLine("The min of int is:{0};\tThe max of int is:{1}", min_int, max_int);

        uint min_uint = 0;
        uint max_uint = (uint)(Math.Pow(2, 32) - 1);
        Console.WriteLine("The min of uint is:{0};\tThe max of uint is:{1}", min_uint, max_uint);

        long min_long = (long)-Math.Pow(2, 63);
        long max_long = (long)(Math.Pow(2, 63) - 1);
        Console.WriteLine("The min of long is:{0};\tThe max of long is:{1}", min_long, max_long);

        ulong min_ulong = 0;
        ulong max_ulong = (ulong)(Math.Pow(2, 64) - 1);
        Console.WriteLine("The min of ulong is:{0};\tThe max of ulong is:{1}", min_ulong, max_ulong);

输出是：

The min of ushort is:0; The max of ushort is:65535
The min of short is:-32768;     The max of short is:32767
The min of int is:-2147483648;  The max of int is:2147483647
The min of uint is:0;   The max of uint is:4294967295
The min of long is:-9223372036854775808;The max of long is:-9223372036854775808
The min of ulong is:0;  The max of ulong is:0

我怀疑这个错误是由Math.Pow()函数引起的，返回的是double类型。

public static double Pow(
    double x,
    double y
)

所以，我的问题是：是否有类似的长类型数学函数？ 如何纠正上面程序片段中的错误。 非常感谢！

你达到了Math.Pow限制。 你需要使用System.Numerics.BigInteger.Pow.
