CONJ(3) Linux Programmer's Manual CONJ(3) 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 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)) VERSIONS These functions first appeared in glibc in version 2.1.
