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.
