Expand description

Function and type bindings for the MPC library.

§Examples

use core::f64;
use core::mem::MaybeUninit;
use gmp_mpfr_sys::{mpc, mpfr};
let one_third = 1.0_f64 / 3.0;
let neg_inf = f64::NEG_INFINITY;
unsafe {
    let mut c = {
        let mut c = MaybeUninit::uninit();
        mpc::init3(c.as_mut_ptr(), 53, 53);
        c.assume_init()
    };
    let dirs = mpc::set_d_d(&mut c, one_third, neg_inf, mpc::RNDNN);
    assert_eq!(dirs, 0);
    let re = mpfr::get_d(mpc::realref_const(&c), mpfr::rnd_t::RNDN);
    assert_eq!(re, one_third);
    let im = mpfr::get_d(mpc::imagref_const(&c), mpfr::rnd_t::RNDN);
    assert_eq!(im, neg_inf);
    mpc::clear(&mut c);
