标准库的 complex

[柯本]

Example

//
// complex.cpp
//
 #include <complex>
 #include <iostream>
 using namespace std;
 int main() 
 {
   complex<double> a(1.2, 3.4);
   complex<double> b(-9.8, -7.6);
   a += b;
   a /= sin(b) * cos(a);
   b *= log(a) + pow(b, a);
   cout << "a = " << a << ", b = " << b << endl;
   return 0;
 }

Program Output

a = (1.42804e-06,-0.0002873), b = (58.2199,69.7354)
