Trait rug::ops::PowFromRound

pub trait PowFromRound<Lhs = Self> {
    type Round;
    type Ordering;
    fn pow_from_round(&mut self, rhs: Lhs, round: Self::Round) -> Self::Ordering;
}

Compound power operation and assignment to the rhs operand with a specified rounding method.

Associated Types

type Round

The rounding method.

type Ordering

The direction from rounding.

Required Methods

fn pow_from_round(&mut self, rhs: Lhs, round: Self::Round) -> Self::Ordering

Performs the power operation.

Examples

use rug::Float;
use rug::float::Round;
use rug::ops::PowFromRound;
use std::cmp::Ordering;
// only four significant bits
let mut f = Float::with_val(4, 5);
let dir = f.pow_from_round(-3, Round::Nearest);
// -243 rounded up to -240
assert_eq!(f, -240);
assert_eq!(dir, Ordering::Greater);
