PROLOG

       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of this interface
       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
       may not be implemented on Linux.

NAME

       cimag, cimagf, cimagl — complex imaginary functions

SYNOPSIS

       #include <complex.h>

       double cimag(double complex z);
       float cimagf(float complex z);
       long double cimagl(long double complex z);

DESCRIPTION

       The  functionality  described  on  this  reference  page is aligned with the ISO C standard. Any conflict
       between the requirements described  here  and  the  ISO C  standard  is  unintentional.  This  volume  of
       POSIX.1‐2017 defers to the ISO C standard.

       These functions shall compute the imaginary part of z.

RETURN VALUE

       These functions shall return the imaginary part value (as a real).

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       For a variable z of complex type:

           z == creal(z) + cimag(z)*I

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
