CONJ(3) Linux Programmer's Manual CONJ(3)
conj, conjf, conjl - calculate the complex conjugate
#include <complex.h>
double complex conj(double complex z);
float complex conjf(float complex z);
long double complex conjl(long double complex z);
Link with -lm.
These functions return the complex conjugate value of z. That is
the value obtained by changing the sign of the imaginary part.
One has:
cabs(z) = csqrt(z * conj(z))
These functions first appeared in glibc in version 2.1.
For an explanation of the terms used in this section, see
attributes(7).
