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

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

Compound remainder operation and assignment with a specified rounding method.

Examples

use core::cmp::Ordering;
use rug::{float::Round, ops::RemAssignRound, Float};
struct F(f64);
impl RemAssignRound<f64> for F {
    type Round = Round;
    type Ordering = Ordering;
    fn rem_assign_round(&mut self, rhs: f64, round: Round) -> Ordering {
        let mut f = Float::with_val(53, self.0);
        let dir = f.rem_assign_round(rhs, round);
        self.0 = f.to_f64();
        dir
    }
}
let mut f = F(3.25);
let dir = f.rem_assign_round(1.25, Round::Nearest);
// 3.25 % 1.25 = 0.75
assert_eq!(f.0, 0.75);
assert_eq!(dir, Ordering::Equal);

Required methods

`fn rem_assign_round(&mut self, rhs: Rhs, round: Self::Round) -> Self::Ordering`[src]

Performs the remainder operation.

Examples

use core::cmp::Ordering;
use rug::{float::Round, ops::RemAssignRound, Float};
// only four significant bits
let mut f = Float::with_val(4, 64);
let dir = f.rem_assign_round(33, Round::Nearest);
// 31 rounded up to 32
assert_eq!(f, 32);
assert_eq!(dir, Ordering::Greater);
