$\begin{signatures} coefficient: & (\%, V) $\to$\ R\\ coefficient: & (\%, \htmlref{\texttt{MachineInteger}}{MachineInteger}) $\to$\ R\\\end{signatures}$

$\begin{params} {\em p} & \% & An element of the free module\\ {\em t} & V & A... ...achineInteger}}{MachineInteger} & The index of a basis element\\\end{params}$

$\begin{retval} coefficient(p, t) returns the coefficient of $p$\ in $t$, while ... ...ent in the built-in enumeration of V given by the lookup function. \end{retval}$

$\begin{remarks} coefficient(p, i) can be used to iterate over all the possible variables in a consistent fashion. The first index is $1$. \end{remarks}$
