NAME¶
conj, conjf, conjl - calculate the complex conjugate
SYNOPSIS¶
#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.
DESCRIPTION¶
The
conj() function returns 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))
VERSIONS¶
These functions first appeared in glibc in version 2.1.
ATTRIBUTES¶
Multithreading (see pthreads(7))¶
The
conj(),
conjf(), and
conjl() functions are thread-safe.
