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
