PROLOG

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

NAME

12       cpow, cpowf, cpowl — complex power functions
13

SYNOPSIS

15       #include <complex.h>
16
17       double complex cpow(double complex x, double complex y);
18       float complex cpowf(float complex x, float complex y);
19       long double complex cpowl(long double complex x,
20           long double complex y);
21

DESCRIPTION

23       The functionality described on this reference page is aligned with  the
24       ISO C  standard.  Any  conflict between the requirements described here
25       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2017
26       defers to the ISO C standard.
27
28       These  functions  shall  compute  the complex power function xy, with a
29       branch cut for the first parameter along the negative real axis.
30

RETURN VALUE

32       These functions shall return the complex power function value.
33
