NAME

13       cpow, cpowf, cpowl — complex power functions
14

SYNOPSIS

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

DESCRIPTION

24       The functionality described on this reference page is aligned with  the
25       ISO C  standard.  Any  conflict between the requirements described here
26       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
27       defers to the ISO C standard.
28
29       These  functions  shall  compute  the complex power function xy, with a
30       branch cut for the first parameter along the negative real axis.
31

RETURN VALUE

33       These functions shall return the complex power function value.
34
