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.
For special values, see clog and cexp.
The cpow
() function conforms to ISO/IEC
9899:2011.
