C# MathF.Atan()用法及代码示例

MathF.Atan(Single)方法用于返回切线作为单值参数给出的角度。如果参数为NaN，则结果将为NaN。

用法： public static float Atan (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。

示例1:

// C# program to demonstrate the 
// MathF.Atan(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 Atan() method 
        float round = MathF.Atan(value); 
  
        // Display the value 
        Console.WriteLine("Angle is {0}", round); 
    } 
}

输出：

Angle is 0.4636476

示例2:

// C# program to demonstrate the 
// MathF.Atan(Single) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        Console.WriteLine("Angle(in radian) are respectively"); 
        get(0.19f); 
        get(0.23f); 
        get(0.45f); 
        get(0.67f); 
    } 
  
    // defining get() method 
    public static void get(float value) 
    { 
  
        // getting absolute angle value in float 
        // using Atan() method 
        float round = MathF.Atan(value); 
  
        // Display the value 
        Console.WriteLine("Angle of Atan({0}) will be {1}", 
                                             value, round); 
    } 
}

输出：

Angle(in radian) are respectively
Angle of Atan(0.19) will be 0.1877619
Angle of Atan(0.23) will be 0.2260684
Angle of Atan(0.45) will be 0.4228539
Angle of Atan(0.67) will be 0.5903068
