Struct LogosRational 

pub struct LogosRational(pub Rational);

Exact rational number for compiled LOGOS programs — the AOT counterpart of the interpreter’s RuntimeValue::Rational.

Wraps the always-reduced [logicaffeine_base::Rational] (a BigInt numerator over a positive BigInt denominator) so a Let x: Rational be 7 / 2 compiles to an exact 7/2 instead of flooring to 3. The type-directed resolve_divisions pass only ever produces these in a Rational-typed context, so the integer floor default is untouched. Display reduces a whole value to a bare integer (6 / 2 → "3"), matching the interpreter.

Implementations

impl LogosRational

pub fn from_i64(n: i64) -> Self

A whole integer as an exact rational (5 → 5/1, shown 5).

pub fn from_ratio(n: i64, d: i64) -> Self

The exact quotient n / d. Panics on a zero denominator, mirroring integer / 0.

pub fn add(&self, other: &LogosRational) -> LogosRational

pub fn sub(&self, other: &LogosRational) -> LogosRational

pub fn mul(&self, other: &LogosRational) -> LogosRational

pub fn div_exact(&self, other: &LogosRational) -> LogosRational

Exact division. Panics on a zero divisor, mirroring integer / 0.

pub fn abs(&self) -> LogosRational

The exact absolute value (a rational stays a rational: |-7/2| = 7/2).

pub fn floor(&self) -> i64

The greatest integer ≤ this rational (toward −∞), computed EXACTLY on the BigInt numerator/denominator — never through a lossy f64.

pub fn ceil(&self) -> i64

The least integer ≥ this rational (toward +∞), computed exactly.

pub fn round(&self) -> i64

The nearest integer, ties away from zero (matching f64::round), computed exactly.

Trait Implementations

impl Clone for LogosRational

fn clone(&self) -> LogosRational

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogosRational

impl Ord for LogosRational

fn cmp(&self, other: &LogosRational) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
