Struct ScientificNumber 

pub struct ScientificNumber { /* private fields */ }

A Haystack scientific notation Number, encapsulating a value and an optional unit value. The unit is represented as a string.

Implementations

impl ScientificNumber

pub fn new( significand: f64, exponent: i32, unit: Option<String>, ) -> Option<ScientificNumber>

Create a new ScientificNumber. If present, the unit should be a valid unit string from Project Haystack’s unit database. The significand must be a finite number which is not NaN.

pub fn new_unitless(significand: f64, exponent: i32) -> Option<ScientificNumber>

Create a new ScientificNumber with no unit. The significand must be a finite number which is not NaN.

pub fn significand(&self) -> f64

Return the numeric significand component of this number.

pub fn exponent(&self) -> i32

Return the numeric exponent component of this number.

pub fn unit(&self) -> Option<&str>

Return the unit component of this number, if present.

pub fn to_axon_code(&self) -> String

Return a string containing Axon code representing this number.

Trait Implementations

impl Clone for ScientificNumber

fn clone(&self) -> ScientificNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScientificNumber

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

Formats the value using the given formatter.

impl Display for ScientificNumber

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

Formats the value using the given formatter.

impl PartialEq for ScientificNumber

fn eq(&self, other: &ScientificNumber) -> 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.
