Signature

generator,terms: % $\to$ Generator Cross(R, Integer)

$\begin{params} {\em p} & \% & A polynomial\\ \end{params}$

$\begin{descr} Both functions allow a polynomial to be iterated independently of... ...exponents, while terms(p) yields the terms in increasing exponents. \end{descr}$

Example

import from Integer, DenseUnivariatePolynomial Integer;

x := monom;
p := x^3 + 2*x - 1;
for term in p repeat { (c, n) := term; print << c << "," << n << newline }
