在複數頭文件中定義了用於複數的exp()函數。該函數是exp()函數的複雜版本。此函數用於計算複數z的基本e index ,並返回複數z的base-e index 。
用法:
template<class T> complex<T> exp (const complex<T>& z );
參數:該方法采用代表複數的強製性參數z。
返回值:此函數返回複數z的base-e index 。
以下示例程序旨在說明C++中的exp()函數:
示例1:
// c++ program to demonstrate
// example of exp() function.
#include <bits/stdc++.h>
using namespace std;
// driver program
int main()
{
// initializing the complex:(-1.0+0.0i)
complex<double> complexnumber(-1.0, 0.0);
// use of exp() function for complex number
cout << "The exp of "
<< complexnumber
<< " is "
<< exp(complexnumber)
<< endl;
return 0;
}
輸出:
The exp of (-1,0) is (0.367879,0)
示例2:
// c++ program to demonstrate
// example of exp() function.
#include <bits/stdc++.h>
using namespace std;
// driver program
int main()
{
// initializing the complex:(0.0 + 1.0i)
complex<double> complexnumber(0.0, 1.0);
// use of exp() function for complex number
cout << "The exp of "
<< complexnumber
<< " is "
<< exp(complexnumber)
<< endl;
return 0;
}
輸出:
The exp of (0,1) is (0.540302,0.841471)
