NAME
     complex -- complex floating-point functions

DESCRIPTION
     The following functions are complex floating-point values, as arguments and return values.  Some use single-precision complex values and some
     use double-precision complex values, as indicated. The functions conform to the ISO/IEC 9899:1999(E) standard. The function prototypes can be
     found in the header file complex.h.

     To use these functions you must add an additional flag to the link step that produces the executable binary. Specify "-lmx".

     These are the functions that use single-precision complex values:

     cabsf()

     cacosf()

     cacoshf()

     cargf()

     casinf()

     casinhf()

     catanf()

     catanhf()

     ccosf()

     ccoshf()

     cexpf()

     cimagf()

     clogf()

     conjf()

     cpowf()

     cprojf()

     crealf()

     csinf()

     csinhf()

     csqrtf()

     ctanf()

     ctanhf()

     These are the functions that use double-precision complex values:

     cabs()

     cacos()

     cacosh()

     carg()

     casin()

     casinh()

     catan()

     catanh()

     ccos()

     ccosh()

     cexp()

     cimag()

     clog()

     conj()

     cpow()

     cproj()

     creal()

     csin()

     csinh()

     csqrt()

     ctan()

     ctanh()
