C＃中的MathF.Cosh()方法与示例

Math.Cosh(Single)方法是内置的MathF类方法，该方法返回给定单值参数的双曲余弦值。

Syntax: public static float Cosh (float x);
Here, x is the number whose hyperbolic cosine is to be returned and type of this parameter is System.Single.

返回值：该方法返回System.Single类型的x的双曲余弦值。如果x等于NegativeInfinity或PositiveInfinity，则返回PositiveInfinity。如果x等于NaN，则返回NaN。

下面的程序说明了上述方法的用法：

范例1：

// C# program to illustrate the
// MathF.Cosh(Single) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main(String[] args)
    {
  
        float num1 = 60.0f, num2 = 0.0f, num3 = 1.0f;
  
        // It returns the hyperbolic cosine 
        // of specified angle in radian
        float coshvalue = MathF.Cosh(num1);
        Console.WriteLine("The Cosh of num1 = " + coshvalue);
  
        coshvalue = MathF.Cosh(num2);
        Console.WriteLine("The Cosh of num2 = " + coshvalue);
  
        coshvalue = MathF.Cosh(num3);
        Console.WriteLine("The Cosh of num3 = " + coshvalue);
    }
}

输出：

The Cosh of num1 = 5.710037E+25
The Cosh of num2 = 1
The Cosh of num3 = 1.543081

范例2：

// C# praogram to illustrate the
// MathF.Cosh(Single) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
          
        float num1 = (30 * (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.Cosh(value);
  
        // Display the value
        Console.WriteLine("Cosh({0}) will be {1}",
                                value, result);
    }
}

输出：

Cosh(0.5235988) will be 1.140238
Cosh(NaN) will be NaN
Cosh(-Infinity) will be Infinity
Cosh(Infinity) will be Infinity
