Struct Bf16 

pub struct Bf16(pub u16);

Brain-float 16-bit floating-point type (bf16).

Stores a u16 that represents the upper 16 bits of an IEEE 754 f32. All arithmetic is performed by widening to f32, computing, then narrowing back – this ensures deterministic results regardless of hardware bf16 support.

Determinism

Conversion uses truncation (not rounding) of the lower 16 mantissa bits, guaranteeing identical results across all platforms.

Implementations

impl Bf16

pub fn from_f32(v: f32) -> Self

Convert f32 to bf16 by truncating lower 16 mantissa bits.

pub fn to_f32(self) -> f32

Convert bf16 to f32 by shifting left 16 bits.

pub fn add(self, rhs: Self) -> Self

Add two bf16 values (widen to f32, add, narrow back).

pub fn sub(self, rhs: Self) -> Self

Subtract two bf16 values (widen to f32, subtract, narrow back).

pub fn mul(self, rhs: Self) -> Self

Multiply two bf16 values (widen to f32, multiply, narrow back).

pub fn div(self, rhs: Self) -> Self

Divide two bf16 values (widen to f32, divide, narrow back).

pub fn neg(self) -> Self

Negate a bf16 value (widen to f32, negate, narrow back).

Trait Implementations

impl Clone for Bf16

fn clone(&self) -> Bf16

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bf16

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

Formats the value using the given formatter.

impl Display for Bf16

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

Formats the value using the given formatter.

impl Hash for Bf16

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Bf16

fn eq(&self, other: &Bf16) -> 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.
