     tions to manipulate complex numbers

LIBRARY

SYNOPSIS

     #include <complex.h>

     double
     cimag(double complex z);

     float
     cimagf(float complex z);

     long double
     cimagl(long double complex z);

     double complex
     conj(double complex z);

     float complex
     conjf(float complex z);

     long double complex
     conjl(long double complex z);

     double
     creal(double complex z);

     float
     crealf(float complex z);

     long double
     creall(long double complex z);

DESCRIPTION

     Let a+b*i denote the complex number z.

     The cimag() functions return the imaginary part b.

     The conj() functions return the complex conjugate a-b*i.

     The creal() functions return the real part a.

STANDARDS

     The cimag(), conj() and creal() functions conform to ISO/IEC 9899:1999
     (``ISO C99'').

HISTORY

     The cimag(), conj() and creal() functions first appeared in FreeBSD 5.3.
