When <em>rational</em> is on, polynomial expressions with rational coefficients
are produced.

</TT></PRE><P>By using <em>rational</em>, polynomial expressions with rational
coefficients can be used in some commands that expect polynomials. With
<em>rational</em> off, such a polynomial becomes a rational expression, with
denominator the least common multiple of the denominators of the rational
number coefficients. <P>
