cpow -- complex power function SYNOPSIS
#include <complex.h> double complex cpow(double complex x, double complex y); long double complex cpowl(long double complex x, long double complex y); float complex cpowf(float complex x, float complex y); DESCRIPTION
cpow(x, y) returns the complex number x raised to the complex power y. cpow(x,y) is equivalent to cexp(y * clog(x)). As such, cpow(x, y) has a branch cut along the negative real axis for the first argument, and the equality cpow(conj(x),conj(y)) = conj(cpow(x,y)) holds for all x and y. SPECIAL VALUES
For special values, see clog and cexp. SEE ALSO

The cpow() function conforms to ISO/IEC 9899:2011. 4th Berkeley Distribution December 11, 2006 4th Berkeley Distribution
