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。
Syntax: public static float Atan (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.
范例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
范例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
