(1) | ||
template< class T > std::complex<T> conj( const std::complex<T>& z ); |
(until C++20) | |
template< class T > constexpr std::complex<T> conj( const std::complex<T>& z ); |

(2) | ||
std::complex<float> conj( float z ); template< class DoubleOrInteger > |
(since C++11) (until C++20) |
|
constexpr std::complex<float> conj( float z ); template< class DoubleOrInteger > |
(since C++20) | |
2) Additional overloads are provided for float, double, long double, and all integer types, which are treated as complex numbers with zero imaginary component.

Parameters
z | - | complex value |
Return value
The complex conjugate of z
Example
Run this code
#include <iostream> #include <complex> int main() { std::complex<double> z(1,2); std::cout << "The conjugate of " << z << " is " << std::conj(z) << '\n' << "Their product is " << z*std::conj(z) << '\n'; }
Output:
The conjugate of (1,2) is (1,-2) Their product is (5,0)
