Struct rug::complex::OrdComplex

pub struct OrdComplex { /* fields omitted */ }

A complex number that supports total ordering and hashing.

For ordering, the real part has precedence over the imaginary part. Negative zero is ordered as less than positive zero. Negative NaN is ordered as less than negative infinity, while positive NaN is ordered as greater than positive infinity. Comparing two negative NaNs or two positive NaNs produces equality.

Examples

use rug::Complex;
use rug::complex::OrdComplex;
use rug::float::Special;
use std::cmp::Ordering;

let nan_c = Complex::with_val(53, (Special::Nan, Special::Nan));
let nan = OrdComplex::from(nan_c);
assert_eq!(nan.cmp(&nan), Ordering::Equal);

let one_neg0_c = Complex::with_val(53, (1, Special::NegZero));
let one_neg0 = OrdComplex::from(one_neg0_c);
let one_pos0_c = Complex::with_val(53, (1, Special::Zero));
let one_pos0 = OrdComplex::from(one_pos0_c);
assert_eq!(one_neg0.cmp(&one_pos0), Ordering::Less);

let zero_inf_s = (Special::Zero, Special::Infinity);
let zero_inf_c = Complex::with_val(53, zero_inf_s);
let zero_inf = OrdComplex::from(zero_inf_c);
assert_eq!(one_pos0.cmp(&zero_inf), Ordering::Greater);

Methods

impl OrdComplex

pub fn as_complex(&self) -> &Complex

Extracts the underlying Complex.

Examples

use rug::Complex;
use rug::complex::OrdComplex;
let c = Complex::with_val(53, (1.5, 2.5));
let ord = OrdComplex::from(c);
let c_ref = ord.as_complex();
assert_eq!(*c_ref.real(), 1.5);
assert_eq!(*c_ref.imag(), 2.5);

pub fn as_complex_mut(&mut self) -> &mut Complex

Extracts the underlying Complex.

Examples

use rug::Complex;
use rug::complex::OrdComplex;
let c = Complex::with_val(53, (1.5, -2.5));
let mut ord = OrdComplex::from(c);
ord.as_complex_mut().conj_mut();
let c_ref = ord.as_complex();
assert_eq!(*c_ref.real(), 1.5);
assert_eq!(*c_ref.imag(), 2.5);
