Implementations

impl Number

fn is_fast_path<F: RawFloat>(&self) -> bool

🔬This is a nightly-only experimental API. (dec2flt)

Detect if the float can be accurately reconstructed from native floats.

pub fn try_fast_path<F: RawFloat>(&self) -> Option<F>

🔬This is a nightly-only experimental API. (dec2flt)

The fast path algorithm using machine-sized integers and floats.

This is extracted into a separate function so that it can be attempted before constructing a Decimal. This only works if both the mantissa and the exponent can be exactly represented as a machine float, since IEE-754 guarantees no rounding will occur.

There is an exception: disguised fast-path cases, where we can shift powers-of-10 from the exponent to the significant digits.

Trait Implementations

impl Clone for Number

fn clone(&self) -> Number

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl Default for Number

fn default() -> Number

Returns the “default value” for a type.

impl Eq for Number

fn assert_receiver_is_total_eq(&self)

impl PartialEq<Number> for Number

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Number

impl StructuralEq for Number

impl StructuralPartialEq for Number
