Module Mpzf

module Mpzf: sig .. end

GMP multi-precision integers, functional version

Functions in this module has a functional semantics, unlike the corresponding functions in Mpz. These functions are less efficients, due to the additional memory allocation neded for the result.

This module could be extended to offer more functions with a functional semantics.

type t

multi-precision integer

val to_mpz : t -> Mpz.t

val of_mpz : Mpz.t -> t

Safe conversion from and to Mpz.t.

There is no sharing between the argument and the result.

val mpz : t -> Mpz.t

val mpzf : Mpz.t -> t

Unsafe conversion from and to Mpz.t.

The argument and the result actually share the same number: be cautious !
