% This function forms product(s) of elements of the array @var{x} along the dimension 
% specified by @var{dim}, analogically to @code{prod}, but avoids overflows and underflows 
% if possible. If called with 2 output arguments, @var{p} and @var{e} are computed 
% so that the product is @code{@var{p} * 2^@var{e}}.
