float8
: 8-bit floating point types for Rust
This crate provides 2 types:
F8E4M3
: Sign + 4-bit exponent + 3-bit mantissa. More precise but less dynamic range.F8E5M2
: Sign + 5-bit exponent + 2-bit mantissa. Less precise but more dynamic range (same exponent asf16
).
Generally, this crate is modelled after the half
crate, so it can be
used alongside and with minimal code changes.
