Struct e5m2 

pub struct e5m2(/* private fields */);

A 8-bit floating point type with 5 exponent bits and 2 mantissa bits.

Implementations

impl e5m2

pub const MAX: f64 = 49152f64

Maximum representable value

pub const MIN: f64 = -49152f64

Minimum representable value

pub const fn from_bits(bits: u8) -> e5m2

Constructs a e5m2 value from the raw bits.

pub const fn from_f32(value: f32) -> e5m2

Constructs a e5m2 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) -> e5m2

Constructs a e5m2 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 e5m2 into the underlying bit representation.

pub const fn to_f32(self) -> f32

Converts a e5m2 value into an f32 value.

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

pub const fn to_f64(self) -> f64

Converts a e5m2 value into an f64 value.

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