padic_ctx_init
Synopsis
#include <flint/padic.h>void padic_ctx_init(padic_ctx_t ctx, const fmpz_t p, slong min, slong max, enum padic_print_mode mode)sourceInitialises ctx for the prime p with precomputed powers p^e for \mathtt{min} \le e < \mathtt{max} and the given printing mode. Throws unless 0 \le \mathtt{min} \le \mathtt{max}. That p is prime is not checked; for composite p the behaviour is undefined.
The table is used by every reduction modulo p^{N - v}, so it should cover the differences N - v that occur, typically from 0 to a little more than the largest precision in use. Other powers are computed when needed. With \mathtt{min} = \mathtt{max} no table is stored.
