% Float to top or a page float. In fact probably only the star form of
% this environment will be used (and that can not do |b| or |h| due to
% a general restriction on double floats.) Also add |!| so that this
% type of float is less likely to float far away, which might cause
% it to be out of sequence with any non-floating numbered equations.
