conj(3) Library Functions Manual conj(3) NAME conj, conjf, conjl - calculate the complex conjugate LIBRARY Math library (libm, -lm) SYNOPSIS #include double complex conj(double complex z); float complex conjf(float complex z); long double complex conjl(long double complex z); 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)) ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). +--------------------------------------------+---------------+---------+ |Interface | Attribute | Value | +--------------------------------------------+---------------+---------+ |conj (), conjf (), conjl () | Thread safety | MT-Safe | +--------------------------------------------+---------------+---------+ STANDARDS C11, POSIX.1-2008.
