fmpz_init2
Synopsis
#include <flint/fmpz.h>Initialises f to zero with space for limbs limbs. If limbs is zero, this is fmpz_init; otherwise an mpz is attached and grown to limbs limbs, so that f is temporarily not in canonical form (its value is 0 in an mpz) until the first assignment. Only useful to avoid reallocations when the final size is known.
