Struct e2m1 

pub struct e2m1(/* private fields */);

A 4-bit floating point type with 2 exponent bits and 1 mantissa bit.

Implementations

impl e2m1

pub const MAX: e2m1

Maximum representable value

pub const MIN: e2m1

Minimum representable value

pub const fn from_bits(bits: u8) -> e2m1

Constructs a e2m1 value from the raw bits.

pub const fn from_f32(value: f32) -> e2m1

Constructs a e2m1 value from a 32-bit floating point value.

This operation is lossy. If the 32-bit value is too large to fit, ±∞ will result. NaN values are preserved. Subnormal values that are too tiny to be represented will result in ±0. All other values are truncated and rounded to the nearest representable value.

pub const fn from_f64(value: f64) -> e2m1

Constructs a e2m1 value from a 64-bit floating point value.

This operation is lossy. If the 64-bit value is to large to fit, ±∞ will result. NaN values are preserved. 64-bit subnormal values are too tiny to be represented and result in ±0. Exponents that underflow the minimum exponent will result in subnormals or ±0. All other values are truncated and rounded to the nearest representable value.

pub const fn to_bits(self) -> u8

Converts a e2m1 into the underlying bit representation.

pub fn to_f32(self) -> f32

Converts a e2m1 value into an f32 value.

This conversion is lossless as all values can be represented exactly in f32.

pub fn to_f64(self) -> f64

Converts a e2m1 value into an f64 value.

This conversion is lossless as all values can be represented exactly in f64.
