-/// A 16-bit floating point type implementing the [`bfloat16`] format.
-///
-/// The [`bfloat16`] floating point format is a truncated 16-bit version of the IEEE 754 standard
-/// `binary32`, a.k.a [`f32`]. [`bf16`] has approximately the same dynamic range as [`f32`] by
-/// having a lower precision than [`f16`][crate::f16]. While [`f16`][crate::f16] has a precision of
-/// 11 bits, [`bf16`] has a precision of only 8 bits.
-///
-/// Like [`f16`][crate::f16], [`bf16`] does not offer arithmetic operations as it is intended for
-/// compact storage rather than calculations. Operations should be performed with [`f32`] or
-/// higher-precision types and converted to/from [`bf16`] as necessary.
