Module Mpfrf

module Mpfrf: sig .. end
MPFR multi-precision floating-point version, functional version

Functions in this module has a functional semantics, unlike the corresponding functions in Mpfr. These functions do not return the rounding information and are less efficients, due to the additional memory allocation neded for the result.
type t = Mpfr.t
multi-precision floating-point numbers
val to_mpfr : t -> Mpfr.t
val of_mpfr : Mpfr.t -> t
Safe conversion from and to Mpfr.t.

There is no sharing between the argument and the result.

val mpfr : t -> Mpfr.t
val mpfrf : Mpfr.t -> t
Unsafe conversion from and to Mpfr.t.

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


Conversion from and to Mpz.t, Mpq.t and Mpfr.t There is no sharing between the argument and the result.
