C# MathF.Tan()用法及代碼示例

MathF.Tan(Single)是內置的MathF類方法，該方法返回給定浮點值參數(指定角度)的切線。

用法： public static float Tan (float x);

Here, x is the angle(measured in radian) whose tangent is to be returned and the type of this parameter is System.Single.

返回值：此方法將返回System.Single類型的x的切線。如果x等於NegativeInfinity，PositiveInfinity或NaN，則此方法返回NaN。

以下示例程序旨在說明上述方法的用法：

示例1:

// C# program to illustrate the 
// MathF.Tan(Single) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main(String[] args) 
    { 
        float a = 152f; 
  
        // converting the value to radians 
        float b = (a * (MathF.PI)) / 180; 
  
        // using method and displaying result 
        Console.WriteLine(MathF.Tan(b)); 
        a = 105f; 
  
        // converting value to radians 
        b = (a * (MathF.PI)) / 180; 
  
        // using method and displaying result 
        Console.WriteLine(MathF.Tan(b)); 
        a = 76F; 
  
        // converting value to radians 
        b = (a * (MathF.PI)) / 180; 
  
        // using method and displaying result 
        Console.WriteLine(MathF.Tan(b)); 
    } 
}

輸出：

-0.5317094
-3.732049
4.010781

示例2:當參數為NaN或無窮大時，顯示MathF.Tan(Single)方法的用法。

// C# program to illustrate the 
// MathF.Tan(Single) Method 
using System; 
  
class Geeks { 
  
    // Main Method 
    public static void Main(String[] args) 
    { 
  
        // Taking the positive, negative 
        // infinity and NaN 
        float positiveInfinity = float.PositiveInfinity; 
        float negativeInfinity = float.NegativeInfinity; 
        float nan = float.NaN; 
  
        float result; 
  
        // Here argument is negative infinity, 
        // so the output will be NaN 
        result = MathF.Tan(negativeInfinity); 
        Console.WriteLine(result); 
  
        // Here argument is positive infinity, 
        // so the output will also be NaN 
        result = MathF.Tan(positiveInfinity); 
        Console.WriteLine(result); 
  
        // Here the argument is NaN, so  
        // the output will be NaN 
        result = MathF.Tan(nan); 
        Console.WriteLine(result); 
    } 
}

輸出：

NaN
NaN
