Struct FixedPoint64 

pub struct FixedPoint64 {
    pub value: u64,
    pub scale: u32,
}

Fixed-point u64 with configurable scale

Fields

value: u64

Raw value (fixed-point)

scale: u32

Decimal places (typically 6 for 1e6 scale)

Implementations

impl FixedPoint64

pub const fn new(value: u64, scale: u32) -> FixedPoint64

Create from raw value and scale

pub fn from_f64(f: f64, scale: u32) -> FixedPoint64

Create from f64

pub fn to_f64(&self) -> f64

Convert to f64

pub fn multiply(&self, other: &FixedPoint64) -> FixedPoint64

Multiply two fixed-point numbers

pub fn ln(&self) -> FixedPoint64

Natural logarithm approximation (fixed-point) Uses polynomial approximation suitable for fixed-point

pub fn tanh(&self) -> FixedPoint64

Tanh approximation (fixed-point)

Trait Implementations

impl Clone for FixedPoint64

fn clone(&self) -> FixedPoint64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FixedPoint64

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

Formats the value using the given formatter.

impl PartialEq for FixedPoint64

fn eq(&self, other: &FixedPoint64) -> 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.
