NAME
conj, conjf, conjl - complex conjugate functions
SYNOPSIS
#include <complex.h>
double complex conj(double complex z);
float complex conjf(float complex z);
long double complex conjl(long double complex z);
DESCRIPTION
[CX] ![[Option Start]](../images/opt-start.gif)
The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the
