\begin{funcdesc}{pow}{x, y\optional{, z}}
Return \var{x} to the power \var{y}; if \var{z} is present, return
\var{x} to the power \var{y}, modulo \var{z} (computed more
efficiently than \code{pow(\var{x}, \var{y}) \%\ \var{z}}). The
arguments must have numeric types. With mixed operand types, the
efficiently than \code{pow(\var{x}, \var{y}) \%\ \var{z}}).
The two-argument form \code{pow(\var{x}, \var{y})} is equivalent to using
the power operator: \code{\var{x}**\var{y}}.
The arguments must have numeric types. With mixed operand types, the
coercion rules for binary arithmetic operators apply. For int and
long int operands, the result has the same type as the operands
(after coercion) unless the second argument is negative; in that
