Tuple Fields

Implementations

impl Float

pub fn to_tight_string(&self) -> String

Tight formatting of floats, where we emit them as integers when they do not have a decimal part used in e.g. the multido.sty binding and test

Trait Implementations

impl Clone for Float

fn clone(&self) -> Float

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Float

impl Debug for Float

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

Formats the value using the given formatter.

impl Default for Float

fn default() -> Self

Returns the “default value” for a type.

impl Display for Float

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

Formats the value using the given formatter.

impl From<&str> for Float

fn from(spec: &str) -> Self

Non-numeric input silently becomes 0.0 (Perl parity — see the From<String> impl).

impl From<Float> for Tokens

fn from(v: Float) -> Tokens

Converts to this type from the input type.

impl From<Float> for Option<Tokens>

fn from(v: Float) -> Option<Tokens>

Converts to this type from the input type.

impl From<Float> for Stored

fn from(value: Float) -> Self

Converts to this type from the input type.

impl From<Float> for ArgWrap

fn from(t: Float) -> Self

Converts to this type from the input type.

impl From<String> for Float

fn from(spec: String) -> Self

Parse a string into a Float. Non-numeric input silently becomes 0.0 to match Perl’s implicit numeric coercion — Float("abc") + x in Perl yields x, not a panic.

impl NumericOps for Float

fn new(number: i64) -> Self

fn new_f64(number: f64) -> Self

fn value_of(self) -> i64

fn value_f64(self) -> f64

fn negate(self) -> Self

fn register_type(&self) -> RegisterType

fn add<T: NumericOps>(self, other: T) -> Self

fn subtract<T: NumericOps>(self, other: T) -> Self

fn multiply<T: NumericOps>(self, other: T) -> Self

fn divide<T: NumericOps>(self, other: T) -> Self

Truncating division

fn unit(&self) -> Option<&'static str>

fn pt_value(self, prec: Option<u8>) -> f64

where Self: Sized,

fn px_value(self, prec: Option<u8>) -> f64

where Self: Sized,

fn absolute(self) -> Self

where Self: Sized,

fn sign(self) -> i8

where Self: Sized,

fn divideround<T: NumericOps>(self, other: T) -> Self

where Self: Sized,

Rounding division

fn smaller<T: NumericOps>(self, other: T) -> Self

where Self: Sized,

fn larger<T: NumericOps>(self, other: T) -> Self

where Self: Sized,

fn to_token(self) -> Token

where Self: Sized,

fn into_glue_type(self) -> Glue

where Self: Sized,

fn to_attribute(&self) -> String

where Self: Display,

impl Object for Float

fn revert(&self) -> Result<Tokens>

each concrete object needs to provide its own path back to tokens

fn stringify(&self) -> String

fn be_digested(self) -> Result<Digested>

fn isa_box(&self) -> bool

fn is_expandable(&self) -> bool

fn is_definition(&self) -> bool

fn is_comment(&self) -> bool

fn get_locator(&self) -> Option<Locator>

The object’s stored source locator, if it has one. None is the honest “no recorded source position” (replacing the old Locator::default() file!()/line!() sentinel). For “where the parser is now” (error reporting, box creation), use the free fn gullet::get_locator().

impl PartialEq for Float

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Float

impl TryFrom<ArgWrap> for Float

type Error = Error

The type returned in the event of a conversion error.

fn try_from(aw: ArgWrap) -> Result<Float>

Performs the conversion.
