Enum NumberValue 

pub enum NumberValue {
    Integer(i64),
    Float(f64),
}

Specialised numeric representation. Integers stay in i64 unless they overflow during arithmetic, in which case the result falls back to f64.

Variants

Integer(i64)

Float(f64)

Implementations

impl NumberValue

pub fn from_i64(value: i64) -> Self

pub fn from_f64(value: f64) -> Self

Construct from an f64. Whole-valued floats within i64 range collapse to Integer so subsequent arithmetic uses the integer fast path.

pub fn is_integer(&self) -> bool

pub fn as_i64(&self) -> Option<i64>

pub fn as_f64(&self) -> f64

pub fn is_zero(&self) -> bool

pub fn is_nan(&self) -> bool

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

Add. Integer-integer uses checked_add; on overflow falls back to f64.

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

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

pub fn div(&self, other: &NumberValue) -> Option<NumberValue>

Divide. Returns None for division by zero — callers handle.

pub fn rem(&self, other: &NumberValue) -> Option<NumberValue>

Modulo. Returns None for division by zero — caller handles.

pub fn neg(&self) -> NumberValue

pub fn abs(&self) -> NumberValue

Trait Implementations

impl Clone for NumberValue

fn clone(&self) -> NumberValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for NumberValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for NumberValue

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for NumberValue

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

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