Struct Decimal

pub struct Decimal { /* private fields */ }

A fixed-point decimal type

Implementations

impl Decimal

pub fn new(mantissa: i64, exponent: usize) -> Decimal

Creates a new Decimal

pub fn mantissa(&self) -> i64

Returns the mantissa

pub fn exponent(&self) -> usize

Returns the exponent

pub fn integer_value(&self, exponent: usize) -> i64

Get the decimal’s value in an integer type, by multiplying by some power of ten to ensure the returned value is 10 ** exponent types the actual value.

pub fn nonnegative(&self) -> bool

Returns whether or not the number is nonnegative

Trait Implementations

impl Add for Decimal

type Output = Decimal

The resulting type after applying the + operator.

fn add(self, other: Decimal) -> Decimal

Performs the + operation.

impl Clone for Decimal

fn clone(&self) -> Decimal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Decimal

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

Formats the value using the given formatter.

impl Display for Decimal

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

Formats the value using the given formatter.

impl Neg for Decimal

type Output = Decimal

The resulting type after applying the - operator.

fn neg(self) -> Decimal

Performs the unary - operation.

impl Ord for Decimal

fn cmp(&self, other: &Decimal) -> 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 min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Decimal

fn eq(&self, other: &Decimal) -> 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 Decimal

fn partial_cmp(&self, other: &Decimal) -> 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.

impl Sub for Decimal

type Output = Decimal

The resulting type after applying the - operator.

fn sub(self, other: Decimal) -> Decimal

Performs the - operation.

impl Copy for Decimal

impl Eq for Decimal
