shift

$\begin{usage} shift(p, m)\\ shift!(p, m) \end{usage}$

Signature

shift: (%,Integer) $\to$ %

$\begin{params} {\em p} & \% & A polynomial or series\\ {\em m} & \htmlref{\texttt{Integer}}{Integer} & The amount to shift\\\end{params}$

$\begin{retval} Returns \begin{displaymath} \sum_{i \ge \max(0,-m)} a_i P_{i+m} \end{displaymath}where $p = \sum_{i \ge 0} a_i P_i$. \end{retval}$

$\begin{remarks} When using shift!, the storage used by p is allowed to be destr... ...and is thus guaranteed not to share space with other polynomials. \end{remarks}$
