conj, conjf, conjl - calculate the complex conjugate

  #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.

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))

These functions first appeared in glibc in version 2.1.

For an explanation of the terms used in this section, see *attributes*(7).
