Comment:
I propose to modify the function padicprec() so that it computes itself
the underlying prime number. Currently, one have:
{{{
sage: K = Qp(11,5)
sage: x = K(5)
sage: x
5 + O(11^5)
sage: y = pari(x)
sage: y.padicprec(11)
5
sage: y.padicprec(17)
*** not the same prime in padicprec.
*** Error in the PARI system. End of program.
}}}
