COMPLEX(3)	      DragonFly Library Functions Manual	    COMPLEX(3)


NAME

     complex -- complex arithmetic


LIBRARY

     Math Library (libm, -lm)


SYNOPSIS

     #include <complex.h>


DESCRIPTION

     These functions support complex arithmetic in the C math library.


LIST OF FUNCTIONS

     Each of the following double complex functions has a float complex coun-
     terpart with an `f' appended to the name and a long double complex coun-
     terpart with an `l' appended.  As an example, the float complex and long
     double complex counterparts of double cabs(double complex z) are float
     cabsf(float complex z) and long double cabsl(long double complex z),
     respectively.
