p-adic shift

Dear all,

I am working on p-adic dynamics and would like to use PARI in library
mode for some of my computations.  One of operations I need to perform
is a p-adic shift.  I know there is a dyadic shift, I would like to
know if there is an analogue for p (apart from the obvious division by
p^n). If not, can I rely on the division by p^n as being exact,
provided I am in the ideal (p^n)?
