conj, conjf, conjl - calculate the complex conjugate
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.
cabs(z) = csqrt(z * conj(z))
These functions first appeared in glibc in version 2.1.
