C＃| Math.Pow()方法

在C＃中， Math.Pow()是Math类方法。此方法用于计算将数字提高到其他数字的乘方。

句法：

public static double Pow(double base, double power)

参数：

double base: It is a double-precision floating-point number which is to be raised to a power and type of this parameter is System.Double.

double power: It is a double-precision floating-point number which specifies a power or exponent and type of this parameter is System.Double.

返回类型：函数返回加到幂的底数。此方法的类型为System.Double

例子：

Input  : base = 8, power =2 
Output : 64

Input  : base = 2.5, power =3
Output : 15.625

程序：演示Math.Pow()

// C# program to illustrate the 
// Math.Pow() function
using System;
class GFG {
  
    // Main Method
    static public void Main()
    {
  
        // Find power using Math.Pow
        // 6 is base and 2 is power or
        // index or exponent of a number
        double pow_ab = Math.Pow(6, 2);
  
        // Print the result
        Console.WriteLine(pow_ab);
  
        // 3.5 is base and 3 is power or
        // index or exponent of a number
        double pow_tt = Math.Pow(3.5, 3);
  
        // Print the result
        Console.WriteLine(pow_tt);
  
        // 202 is base and 4 is power or
        // index or exponent of a number
        double pow_t = Math.Pow(202, 4);
  
        // Print the result
        Console.WriteLine(pow_t);
    }
}

输出：
