[−][src]Trait rug::ops::AddAssignRound

pub trait AddAssignRound<Rhs = Self> {
    type Round;
    type Ordering;
    fn add_assign_round(
        &mut self, 
        rhs: Rhs, 
        round: Self::Round
    ) -> Self::Ordering;
}

Compound addition and assignment with a specified rounding method.

Examples

use core::cmp::Ordering;
use rug::{float::Round, ops::AddAssignRound, Float};
struct F(f64);
impl AddAssignRound<f64> for F {
    type Round = Round;
    type Ordering = Ordering;
    fn add_assign_round(&mut self, rhs: f64, round: Round) -> Ordering {
        let mut f = Float::with_val(53, self.0);
        let dir = f.add_assign_round(rhs, round);
        self.0 = f.to_f64();
        dir
    }
}
let mut f = F(3.0);
let dir = f.add_assign_round(5.0, Round::Nearest);
// 3.0 + 5.0 = 8.0
assert_eq!(f.0, 8.0);
assert_eq!(dir, Ordering::Equal);

Associated Types

Required methods

`fn add_assign_round(&mut self, rhs: Rhs, round: Self::Round) -> Self::Ordering`

Performs the addition.

Examples

use core::cmp::Ordering;
use rug::{float::Round, ops::AddAssignRound, Float};
// only four significant bits
let mut f = Float::with_val(4, -3);
let dir = f.add_assign_round(-0.3, Round::Nearest);
// −3.3 rounded up to −3.25
assert_eq!(f, -3.25);
assert_eq!(dir, Ordering::Greater);
