Let the rational function r(x) = p(x)/q(x), where p(x) and q(x) are polynomials.
This function provides the coefficients of the numerator p(x).
Hence, p(x) is of degree np-1.
If np is zero, then the numerator is assumed to be p(x)=1.
<P>
In polynomials, high order coefficients are stored in the first positions
of the array, e.g. to represent x^2-3 use {1,0,-3}.
