+Exponentiation \lstinline!a ^ b! always returns a \lstinline!Real! scalar value, and it is required that \lstinline!a! and \lstinline!b! are scalar \lstinline!Real! or \lstinline!Integer! values.
 The result should correspond to mathematical exponentiation (ideally the correctly rounded result based on the inputs) with the following special cases:
 \begin{itemize}
 \item If $\text{\lstinline!a!} = 0.0$ and $\text{\lstinline!b!} = 0$ for an \lstinline!Integer! expression \lstinline!b! the result is $0.0$.
