MathF.Asin() Method in C# with Examples

  • Last Updated : 04 Apr, 2019

MathF.Asin() Method is used to return the angle whose sine is given as a single(or float) value argument. If the argument is NaN, then the result will be NaN.

Syntax: public static float Asin (float x);
Here, it takes a standard floating point number.

Return Value: This method returns an angle θ, measured in radians, its type is System.Single and value will be less than Single.MaxValue.

Below programs will illustrate the use of the above-discussed method:

Example 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);
    }
}
Output:
Angle is 0.7753975

Example 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);
    }
}
Output:
Asin(0.19) will be 0.1911621
Asin(NaN) will be NaN
Asin(-Infinity) will be NaN
Asin(Infinity) will be NaN
