C# Math.Tanh()用法及代码示例


Math.Tanh()是内置的Math类方法,该方法返回给定双值参数的双曲线正切。如果给定参数为NaN,则结果将为NaN。

用法:

public static double Tanh(double num)

参数:


  • num:它是要返回其双曲线tan的数字,并且此参数的类型为System.Double。

返回值:该方法返回num的双曲正切。类型System.Double。如果num等于NegativeInfinity,则此方法返回-1。如果num等于PositiveInfinity,则此方法返回1。如果num等于NaN,则此方法返回NaN。

例子:

Input  : num = 60.0
Output : 1.0

以下示例程序旨在说明Math.Tanh()方法:

示例1:

// C# program to illustrate the 
// Math.Tanh() 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main(String[] args) 
    { 
  
        double num1 = 60.0, num2 = 0.0, num3 = 1.0; 
  
        // It returns the hyperbolic tan of  
        // specified  angle in radian 
        double tanhvalue = Math.Tanh(num1); 
        Console.WriteLine("The tanh of num1 = " + tanhvalue); 
  
        tanhvalue = Math.Tanh(num2); 
        Console.WriteLine("The tanh of num2 = " + tanhvalue); 
  
        tanhvalue = Math.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 = 0.761594155955765

示例2:

// C# praogram to illustrate the 
// Math.Tanh() Method 
using System; 
  
class GFG { 
     
    // Main Method 
    public static void Main(String[] args) 
    { 
  
        double num1 = (30 * (Math.PI)) / 180, num2 = 11.0, num3 = 45.0; 
  
        // It returns the hyperbolic tan of  
        // angle in radian 
        double tanhvalue = Math.Tanh(num1); 
        Console.WriteLine("The tanh of num1 = " + tanhvalue); 
  
        tanhvalue = Math.Tanh(num2); 
        Console.WriteLine("The tanh of num2 = " + tanhvalue); 
  
        tanhvalue = Math.Tanh(num3); 
        Console.WriteLine("The tanh of num3 = " + tanhvalue); 
    } 
}
输出:
The tanh of num1 = 0.480472778156452
The tanh of num2 = 0.999999999442106
The tanh of num3 = 1
