  FUNCTION
          <<conj>>, <<conjf>>---complex conjugate
  
  INDEX
          conj
  INDEX
          conjf
  
  SYNOPSIS
         #include <complex.h>
         double complex conj(double complex <[z]>);
         float complex conjf(float complex <[z]>);
  
  
  DESCRIPTION
          These functions compute the complex conjugate of <[z]>, 
          by reversing the sign of its imaginary part.
  
          <<conjf>> is identical to <<conj>>, except that it performs
          its calculations on <<floats complex>>.
  
  RETURNS
          The conj functions return the complex conjugate value.
  
  PORTABILITY
          <<conj>> and <<conjf>> are ISO C99
  
  QUICKREF
          <<conj>> and <<conjf>> are ISO C99
