在複數頭文件中定義了用於複數的tanh()函數。此函數是cmath頭文件tanh()函數的複雜版本。此函數用於計算複數z的複雙曲正切。
用法:
template<class T> complex<T> tanh (const complex<T>& z );
參數:
- z:該方法采用代表複數的mandaory參數z。
返回值:此函數返回複數z的雙曲正切。
以下示例程序旨在說明C++中的tanh()函數:
範例1:
// C++ program to demonstrate
// example of tanh() function.
#include <bits/stdc++.h>
using namespace std;
int main ()
{
complex<double> complexnumber (0.0, 1.0);
// use of tanh() function for complex number
cout << "The tanh of " << complexnumber << " is "
<< tanh(complexnumber) <<endl;
return 0;
}
輸出:
The tanh of (0,1) is (0,1.55741)
範例2:
// C++ program to demonstrate
// example of tanh() function.
#include <bits/stdc++.h>
using namespace std;
int main ()
{
complex<double> complexnumber (1.0, 0.0);
// use of tanh() function for complex number
cout << "The tanh of " << complexnumber << " is "
<< tanh(complexnumber) << endl;
return 0;
}
輸出:
The tanh of (1,0) is (0.761594,0)
