template< class T > complex<T> pow( const T& x, const complex<T>& y);
template< class T, class U > complex</*Promoted*/> pow( const complex<T>& x, const complex<U>& y);		(since C++11)

template< class T, class U > complex</*Promoted*/> pow( const T& x, const complex<U>& y);		(since C++11)

Computes complex x raised to a complex power y. The operation is defined as exp(y · log(x) ). A branch cut exists along the negative real axis.

The result of pow(0, 0) is implementation-defined.

(since C++11)Additional overloads are provided for all arithmetic types, such that

1. If either argument is long double or std::complex<long double>, then both arguments are cast to std::complex<long double>

2. Otherwise, if either argument is double, std::complex<double> or integer type, then both arguments are cast to std::complex<double>

3. Otherwise, if either argument is float or std::complex<float>, then both arguments are cast to std::complex<float>

Parameters

x	-	base as a complex value
y	-	exponent as a complex value

Return value

x raised to a power y.
