Function and type bindings for the [MPFR] library. # Examples ```rust use gmp_mpfr_sys::mpfr; use std::mem; let one_third = 1.0_f64 / 3.0; unsafe { let mut f = mem::uninitialized(); mpfr::init2(&mut f, 53); let dir = mpfr::set_d(&mut f, one_third, mpfr::rnd_t::RNDN); assert_eq!(dir, 0); let d = mpfr::get_d(&f, mpfr::rnd_t::RNDN); assert_eq!(d, one_third); mpfr::clear(&mut f); } ``` The following example is a translation of the [MPFR sample] found on the [MPFR] website. The program computes a lower bound on 1 + 1/1! + 1/2! + … + 1/100! using 200-bit precision. The program writes: `Sum is 2.7182818284590452353602874713526624977572470936999595749669131` ```rust use gmp_mpfr_sys::mpfr::{self, mpfr_t, rnd_t}; use std::ffi::CStr; use std::fmt::Write; use std::mem; use std::os::raw::c_int; use std::ptr; fn main() { unsafe { let mut s = mem::uninitialized(); let mut t = mem::uninitialized(); let mut u = mem::uninitialized(); mpfr::init2(&mut t, 200); mpfr::set_d(&mut t, 1.0, rnd_t::RNDD); mpfr::init2(&mut s, 200); mpfr::set_d(&mut s, 1.0, rnd_t::RNDD); mpfr::init2(&mut u, 200); for i in 1..101 { mpfr::mul_ui(&mut t, &t, i, rnd_t::RNDU); mpfr::set_d(&mut u, 1.0, rnd_t::RNDD); mpfr::div(&mut u, &u, &t, rnd_t::RNDD); mpfr::add(&mut s, &s, &u, rnd_t::RNDD); } let sr = mpfr_to_string(10, 0, &s, rnd_t::RNDD); println!("Sum is {}", sr); mpfr::clear(&mut s); mpfr::clear(&mut t); mpfr::clear(&mut u); # assert_eq!( # sr, # "2.7182818284590452353602874713526624977572470936999595749669131" # ); } } unsafe fn mpfr_to_string( base: c_int, n: usize, op: *const mpfr_t, rnd: rnd_t ) -> String { let mut exp = mem::uninitialized(); let str = mpfr::get_str(ptr::null_mut(), &mut exp, base, n, op, rnd); let mut buf = CStr::from_ptr(str).to_string_lossy().into_owned(); mpfr::free_str(str); if mpfr::regular_p(op) != 0 { let idx = if buf.starts_with("-") { 2 } else { 1 }; buf.insert(idx, '.'); if exp != 1 { buf.push(if base <= 10 { 'e' } else { '@' }); write!(buf, "{}", exp - 1).unwrap(); } } buf } ``` [MPFR sample]: (https://www.mpfr.org/sample.html) [MPFR]: https://www.mpfr.org/ */ #![allow(non_camel_case_types, non_snake_case)] use gmp; use libc::{intmax_t, uintmax_t, FILE}; use misc; use std::mem; use std::os::raw::{c_char, c_int, c_long, c_uint, c_ulong, c_void}; /// See: [`mpfr_prec_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005fprec_005ft) pub type prec_t = c_long; // TODO: breaking change: do not use enum /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) #[repr(C)] #[derive(Clone, Copy, Debug)] #[allow(deprecated)] pub enum rnd_t { /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) RNDN = 0, /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) RNDZ = 1, /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) RNDU = 2, /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) RNDD = 3, /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) RNDA = 4, /// See: [`mpfr_rnd_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005frnd_005ft) RNDF = 5, #[doc(hidden)] #[deprecated(since = "1.1.0", note = "do not use!")] RNDNA = -1, } /// See: [`mpfr_flags_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005fflags_005ft) pub type flags_t = c_uint; /// See: [Exception Related Functions](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Interface.html#Exception-Related-Functions) pub type exp_t = c_long; type uexp_t = c_ulong; /// See: [Nomenclature and Types](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#Nomenclature-and-Types) pub const PREC_MIN: prec_t = 1; /// See: [Nomenclature and Types](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#Nomenclature-and-Types) pub const PREC_MAX: prec_t = ((!(0 as uprec_t) >> 1) - 256) as prec_t; /// See: [`mpfr_t`](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Basics.html#index-mpfr_005ft) /// and [Internals](https://tspiteri.gitlab.io/gmp-mpfr-sys/mpfr/MPFR-Interface.html#Internals) /// /// # Compatibility note /// /// The fields listed here are considered internal details.
