C# MathF.Tanh()用法及代码示例

Math.Tanh(Single)方法是内置的MathF类方法，它返回给定单值参数的双曲正切值。

用法： public static float Tanh (float x);

Here, x is the number whose hyperbolic tangent is to be returned and type of this parameter is System.Single.

返回值：此方法返回System.Single类型的x的双曲正切值。如果x等于NegativeInfinity或PositiveInfinity，则返回PositiveInfinity。如果x等于NaN，则返回NaN。

以下示例程序旨在说明上述方法的用法：

示例1:

// C# program to illustrate the 
// MathF.Tanh(Single) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main(String[] args) 
    { 
  
        float num1 = 70.0f, num2 = 0.0f, num3 = 1.0f; 
  
        // It returns the hyperbolic tangent 
        // of specified angle in radian 
        float tanhvalue = MathF.Tanh(num1); 
        Console.WriteLine("The Tanh of num1 = " + tanhvalue); 
  
        tanhvalue = MathF.Tanh(num2); 
        Console.WriteLine("The Tanh of num2 = " + tanhvalue); 
  
        tanhvalue = MathF.Tanh(num3); 
        Console.WriteLine("The Tanh of num3 = " + tanhvalue); 
    } 
}

输出：

The Tanh of num1 = 1
The Tanh of num2 = 0
The Tanh of num3 = 0.7615942

示例2:

// C# praogram to illustrate the 
// MathF.Tanh(Single) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
          
        float num1 = (90 * (MathF.PI)) / 180; 
          
        // calling result() method 
        result(num1); 
        result(Single.NaN); 
        result(Single.NegativeInfinity); 
        result(Single.PositiveInfinity); 
    } 
  
    // defining result() method 
    public static void result(float value) 
    { 
  
        // using the method 
        float result = MathF.Tanh(value); 
  
        // Display the value 
        Console.WriteLine("Tanh({0}) will be {1}", 
                                   value, result); 
    } 
}

输出：

Tanh(1.570796) will be 0.9171523
Tanh(NaN) will be NaN
Tanh(-Infinity) will be -1
Tanh(Infinity) will be 1
