 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 $0.0$.
+\item If $\text{\lstinline!a!} = 0.0$ and $\text{\lstinline!b!} = 0$ for an \lstinline!Integer! expression \lstinline!b! the result is $1.0$.
 \item If $\text{\lstinline!a!} < 0$ and \lstinline!b! is an \lstinline!Integer! or a \lstinline!Real! having an integer value, the result is defined as $\pm |a|^b$, with sign depending on whether \lstinline!b! is even (positive) or odd (negative).
 \item Consequences of other exceptional situations, such as ($\text{\lstinline!a!} = 0.0$ and $\text{\lstinline!b!} = 0.0$ for a \lstinline!Real b!, $\text{\lstinline!a!} = 0.0$ and $\text{\lstinline!b!} < 0$, or $\text{\lstinline!a!} < 0$ and \lstinline!b! does not have an integer value) or overflow are undefined.
