MathF.Asin()方法用于返回其正弦值作为单个(或浮点)值参数给出的角度。如果参数为NaN,则结果将为NaN。

下面的程序将说明上述方法的使用:

范例1:

// C# program to demonstrate the
// MathF.Asin(Single)  Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring and initializing value
        float value = 0.7f;
  
        // getting absolute angle value in float
        // using Asin() method
        float result = MathF.Asin(value);
  
        // Display the value
        Console.WriteLine("Angle is {0}", result);
    }
}
输出:
Angle is 0.7753975

范例2:

// C# program to demonstrate the
// MathF.Asin(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 Asin() method
        float result = MathF.Asin(value);
  
        // Display the value
        Console.WriteLine("Asin({0}) will be {1}",
                                   value, result);
    }
}
输出:
Asin(0.19) will be 0.1911621
Asin(NaN) will be NaN
Asin(-Infinity) will be NaN
Asin(Infinity) will be NaN
