Struct DecimalNumber

pub struct DecimalNumber { /* private fields */ }

Stores the integral/integer and fractional parts of a number written in decimal representation as strings.

For example: 3.14159265 has integral = ‘3’ and fractional = ‘14159265’

Implementations

impl DecimalNumber

pub fn new(text: &str) -> DecimalNumber

pub fn full_number(&self) -> String

pub fn sig_figs(&self) -> usize

Returns the number of significant figures of the DecimalNumber

Examples:

• “83.2” has 3 sig figs
• “0.032” has 2 sig figs(note the preceding zeroes)
• “788” has 3 sig figs
• “78800” also has 3 sig figs(note the trailing zeroes)
• “78801” has 5 sig figs

pub fn as_float(&self) -> f64

Trait Implementations

impl Clone for DecimalNumber

fn clone(&self) -> DecimalNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecimalNumber

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

Formats the value using the given formatter.

impl Display for DecimalNumber

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

Formats the value using the given formatter.

impl PartialEq for DecimalNumber

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