% \begin{macro}{\@settopoint}
%    This macro takes the contents of the skip register that is
%    supplied as its argument and removes the fractional part to make
%    it a whole number of points. This can be used in class files to
%    avoid values like |345.4666666pt| when calulating a dimension.
