conj(3)                 Library Functions Manual                 conj(3)

NAME         top

       conj, conjf, conjl - calculate the complex conjugate

LIBRARY         top

       Math library (libm, -lm)

SYNOPSIS         top

       #include <complex.h>

       double complex conj(double complex z);
       float complex conjf(float complex z);
       long double complex conjl(long double complex z);

DESCRIPTION         top

       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))
