infix:<**>
Combined from primary sources listed below.

In Complex§

See primary documentation in context for sub infix:<**>. 

multi infix:<**>(Complex:D \a, Complex:D \b --> Complex:D)
multi infix:<**>(Num(Real) \a, Complex:D \b --> Complex:D)
multi infix:<**>(Complex:D \a, Num(Real) \b --> Complex:D)

The exponentiation operator coerces the second argument to Complex and calculates the left-hand-side raised to the power of the right-hand side. Since 6.d, either argument can be equal to zero.
