COMPLEX(3)             FreeBSD 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
     counterpart with an `f' appended to the name and a long double complex
     counterpart 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.
