bf16 floating point types for Rust
bf16 types provides conversion operations as a normal Rust floating point type, but since they are primarily leveraged for
minimal floating point storage and most major hardware does not implement them, all math operations should be done as an
This crate provides
no_std support by default so can easily be used in embedded
code where a smaller float format is most useful.
Requries Rust 1.32 or greater. If you need support for older versions of Rust, use versions 1.3 and earlier of this crate.
See the crate documentation for more details.
bf16. This adds a dependency on the
use-intrinsics- Use hardware intrinsics for
bf16conversions if available on the compiler host target. By default, without this feature, conversions are done only in software, which will be the fallback if the host target does not have hardware support. Available only on Rust nightly channel.
alloc- Enable use of the
alloccrate when not using the
This enables the
vecmodule, which contains zero-copy conversions for the
Vectype. This allows fast conversion between raw
Vec<bf16>arrays, and vice versa. Requires Rust 1.36 or greater.
std- Enable features that depend on the Rust
stdlibrary, including everything in the
stdfeature enables runtime CPU feature detection when the
use-intrsincisfeature is also enabled. Without this feature detection, intrinsics are only used when compiler host target supports them.
