C# MathF.Acos()用法及代码示例

MathF.Acos(Single)方法用于返回以余弦值作为单个或浮点值参数给出的角度。如果参数为NaN，则结果将为NaN。

用法： public static float Acos (float x);

Here, it takes a standard floating point number.

返回值：此方法返回以弧度为单位的角度θ，其类型为System.Single，其值小于Single.MaxValue。

下面的程序将说明上述方法的使用：

示例1:

// C# program to demonstrate the 
// MathF.Acos(Single) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring and initializing value 
        float value = 0.5f; 
  
        // getting absolute angle value in float 
        // using Acos() method 
        float result = MathF.Acos(value); 
  
        // Display the value 
        Console.WriteLine("Angle is {0}", result); 
    } 
}

输出：

Angle is 1.047198

示例2:

// C# program to demonstrate the 
// MathF.Acos(Single) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(0.19f); 
        get(Single.NaN); 
        get(Single.NegativeInfinity); 
        get(Single.PositiveInfinity); 
    } 
  
    // defining get() method 
    public static void get(float value) 
    { 
  
        // getting absolute angle value in float 
        // using Acos() method 
        float result = MathF.Acos(value); 
  
        // Display the value 
        Console.WriteLine("Acos({0}) will be {1}", 
                                   value, result); 
    } 
}

输出：

Acos(0.19) will be 1.379634
Acos(NaN) will be NaN
Acos(-Infinity) will be NaN
Acos(Infinity) will be NaN
