MathF。C# 中的 Tan()方法及示例
原文:https://www . geesforgeks . org/mathf-tan-method-in-c-sharp-with-examples/
MathF。Tan(Single) 是一个内置的 MathF 类方法，它返回给定浮点值参数(指定角度)的正切值。
句法:公静浮檀(浮 x)； 这里，x 是切线返回的角度(以弧度为单位)，该参数的类型为系统。单身。
返回值:该方法将返回系统类型的 x 的切线。单。如果 x 等于 NegativeInfinity、PositiveInfinity 或 NaN ，则该方法返回 NaN 。
以下程序说明了上述方法的使用:
例 1:
// C# program to illustrate the
// MathF.Tan(Single) Method
using System;
class GFG {
// Main Method
public static void Main(String[] args)
{
float a = 152f;
// converting the value to radians
float b = (a * (MathF.PI)) / 180;
// using method and displaying result
Console.WriteLine(MathF.Tan(b));
a = 105f;
// converting value to radians
b = (a * (MathF.PI)) / 180;
// using method and displaying result
Console.WriteLine(MathF.Tan(b));
a = 76F;
// converting value to radians
b = (a * (MathF.PI)) / 180;
// using method and displaying result
Console.WriteLine(MathF.Tan(b));
}
}
Output:
-0.5317094
-3.732049
4.010781
例 2: 展示 MathF 的工作原理。谭(单)法当论证是 NaN 还是无穷大。
// C# program to illustrate the
// MathF.Tan(Single) Method
using System;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Taking the positive, negative
// infinity and NaN
float positiveInfinity = float.PositiveInfinity;
float negativeInfinity = float.NegativeInfinity;
float nan = float.NaN;
float result;
// Here argument is negative infinity,
// so the output will be NaN
result = MathF.Tan(negativeInfinity);
Console.WriteLine(result);
// Here argument is positive infinity,
// so the output will also be NaN
result = MathF.Tan(positiveInfinity);
Console.WriteLine(result);
// Here the argument is NaN, so
// the output will be NaN
result = MathF.Tan(nan);
Console.WriteLine(result);
}
}
Output:
NaN
NaN
NaN
