| template< class T > complex<T> conj( const complex<T>& z ); |
(1) | |
| std::complex<long double> conj( long double z ); |
(2) | (since C++11) |
| template< class DoubleOrInteger > std::complex<double> conj( DoubleOrInteger z ); |
(3) | (since C++11) |
| std::complex<float> conj( float z ); |
(4) | (since C++11) |
Computes the complex conjugate of z by reversing the sign of the imaginary part.
(since C++11)Additional overloads are provided for float, double, long double, and all integer types, which are treated as complex numbers with zero imaginary component.

| 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)
