MathF。C# 中的 Tanh()方法，带示例
原文:https://www . geesforgeks . org/mathf-tanh-method-in-c-sharp-with-examples/
数学。Tanh(Single) 方法是内置的 MathF 类方法，它返回给定单值参数的双曲正切值。
语法:公共静态 float Tanh(float x)； 这里，x 是要返回双曲正切的数字，这个参数的类型是系统。单身。
返回值:此方法返回类型为系统的 x 的双曲正切值。单。如果 x 等于否定有限性或肯定有限性，则返回肯定有限性。如果 x 等于 NaN，则返回 NaN。 以下程序说明了上述方法的使用: 例 1:
c sharp . c sharp . c sharp . c sharp
// C# program to illustrate the
// MathF.Tanh(Single) Method
using System;
class GFG {
// Main Method
public static void Main(String[] args)
{
float num1 = 70.0f, num2 = 0.0f, num3 = 1.0f;
// It returns the hyperbolic tangent
// of specified angle in radian
float tanhvalue = MathF.Tanh(num1);
Console.WriteLine("The Tanh of num1 = " + tanhvalue);
tanhvalue = MathF.Tanh(num2);
Console.WriteLine("The Tanh of num2 = " + tanhvalue);
tanhvalue = MathF.Tanh(num3);
Console.WriteLine("The Tanh of num3 = " + tanhvalue);
}
}
Output:
The Tanh of num1 = 1
The Tanh of num2 = 0
The Tanh of num3 = 0.7615942
例 2:
c sharp . c sharp . c sharp . c sharp
// C# program to illustrate the
// MathF.Tanh(Single) Method
using System;
class GFG {
// Main Method
public static void Main()
{
float num1 = (90 * (MathF.PI)) / 180;
// calling result() method
result(num1);
result(Single.NaN);
result(Single.NegativeInfinity);
result(Single.PositiveInfinity);
}
// defining result() method
public static void result(float value)
{
// using the method
float result = MathF.Tanh(value);
// Display the value
Console.WriteLine("Tanh({0}) will be {1}",
value, result);
}
}
Output:
Tanh(1.570796) will be 0.9171523
Tanh(NaN) will be NaN
Tanh(-Infinity) will be -1
Tanh(Infinity) will be 1
