MathF。C# 中的 Atan()方法,带示例

原文:https://www . geesforgeks . org/mathf-atan-method-in-c-sharp-with-examples/

MathF。Atan(Single) 方法用于返回切线作为单值参数给出的角度。如果参数是 NaN,那么结果就是 NaN。

语法:公共静态 float Atan(float x); 这里,它取一个标准的浮点数。

返回值:该方法返回一个角度θ,以弧度为单位,类型为系统。单值和值将小于单值。最大值

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);
    }
}

Output:

Angle is 0.4636476

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);
    }
}

Output:

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
