Struct dashu_float::round::mode::Zero

pub struct Zero;

Round toward 0 (default mode for binary float)

Trait Implementations

impl Clone for Zero

fn clone(&self) -> Zero

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Round for Zero

type Reverse = Away

The rounding operation that rounds to an opposite direction

fn round_low_part<F: FnOnce() -> Ordering>(
    integer: &IBig,
    low_sign: Sign,
    _low_half_test: F
) -> Rounding

Calculate the rounding of the number (integer + rem), assuming rem != 0 and |rem| < 1. low_half_test should tell |rem|.cmp(0.5)

fn round_fract<const B: Word>(
    integer: &IBig,
    fract: IBig,
    precision: usize
) -> Rounding

Calculate the rounding of the number (integer + fract / X^precision), assuming |fract| / X^precision < 1. Return the adjustment.

fn round_ratio(integer: &IBig, num: IBig, den: &IBig) -> Rounding

Calculate the rounding of the number (integer + numerator / denominator), assuming |numerator / denominator| < 1. Return the adjustment.
