Implementa os operadores binários para aritmética complexa e de aritmética complexa / escalar mista. Argumentos escalares são tratados como números complexos com a parte real igual ao argumento ea parte imaginária definida para zero.
Original:
Implements the binary operators for complex arithmetic and for mixed complex/scalar arithmetic. Scalar arguments are treated as complex numbers with the real part equal to the argument and the imaginary part set to zero.

Parâmetros
| lhs, rhs | - | os argumentos: ou ambos os números complexos ou um complexo e um escalares do tipo de correspondência ( Original: the arguments: either both complex numbers or one complex and one scalar of matching type ( The text has been machine-translated via Google Translate. |
Valor de retorno
1-3) complex<T>(lhs) += rhs
4-6) complex<T>(lhs) -= rhs
7-9) complex<T>(lhs) *= rhs
10-12) complex<T>(lhs) /= rhs
Exemplo
#include <iostream> #include <complex> int main() { std::complex<double> c2(2, 0); std::complex<double> ci(0, 1); std::cout << ci << " + " << c2 << " = " << ci+c2 << '\n' << ci << " * " << ci << " = " << ci*ci << '\n' << ci << " + " << c2 << " / " << ci << " = " << ci+c2/ci << '\n' << 1 << " / " << ci << " = " << 1./ci << '\n'; // std::cout << 1.f/ci; // compile error // std::cout << 1/ci; // compile error }
Saída:
(0,1) + (2,0) = (2,1) (0,1) * (0,1) = (-1,0) (0,1) + (2,0) / (0,1) = (0,-1) 1 / (0,1) = (0,-1)
