pow

template<class T> complex<T> pow (const complex<T>& x, int y);
template<class T> complex<T> pow (const complex<T>& x, const complex<T>& y);
template<class T> complex<T> pow (const complex<T>& x, const T& y);
template<class T> complex<T> pow (const T& x, const complex<T>& y);

Returns the complex power of base x raised to the y-th power using the principal branch, whose cuts are along the negative real axis, as if computed by:



This overloads cmath's pow function.

Parameters

x

Base value.
T is complex's template type (i.e., its value type).

y

Exponent value.
T is complex's template type (i.e., its value type).

Return value

The result of raising x to the y-th power.
Each library implementation defines how range and domain errors are signaled.
