[−][src]Trait rug::ops::AddFromRound
Compound addition and assignment to the rhs operand with a specified rounding method.
Examples
use core::cmp::Ordering; use rug::{ float::Round, ops::{AddAssignRound, AddFromRound}, Float, }; struct F(f64); impl AddFromRound<f64> for F { type Round = Round; type Ordering = Ordering; fn add_from_round(&mut self, lhs: f64, round: Round) -> Ordering { let mut f = Float::with_val(53, lhs); let dir = f.add_assign_round(self.0, round); self.0 = f.to_f64(); dir } } let mut f = F(5.0); let dir = f.add_from_round(3.0, Round::Nearest); // 3.0 + 5.0 = 8.0 assert_eq!(f.0, 8.0); assert_eq!(dir, Ordering::Equal);

fn add_from_round(&mut self, lhs: Lhs, round: Self::Round) -> Self::Ordering
Performs the addition.
Examples
use core::cmp::Ordering; use rug::{float::Round, ops::AddFromRound, Float}; // only four significant bits let mut f = Float::with_val(4, -0.3); let dir = f.add_from_round(-3, Round::Nearest); // −3.3 rounded up to −3.25 assert_eq!(f, -3.25); assert_eq!(dir, Ordering::Greater);
