## Summary Adds **bfloat16** and **bfloat16_array** support to the Fory JavaScript runtime and codegen, following the same structure as the existing float16 implementation. Fixes #3288 ## Changes ### Runtime - **BFloat16** class with `fromBits()` / `toBits()` and `fromFloat32()` / `toFloat32()` (IEEE 754 compliant, round-to-nearest ties-to-even for float32→bfloat16). - **BFloat16Array** backed by `Uint16Array` for packed bfloat16 arrays; supports iteration and `fromRaw()` for deserialization. - Wire format: 2 bytes per value (little-endian), matching existing float32/float64 behavior. NaN/Inf/±0/subnormals round-trip correctly. ### Type system & serialization - `Type.bfloat16()` and `Type.bfloat16Array()`. - Serializers registered in type resolver; reader returns `BFloat16` (no raw uint16 in public API). - Codegen: `gen/builder.ts`, `gen/number.ts`, and `gen/typedArray.ts` updated for bfloat16 and bfloat16_array. ### API - `BFloat16` and `BFloat16Array` exported from the package. - Writer accepts `BFloat16 | number` for scalar bfloat16; arrays accept `BFloat16[]` or `BFloat16Array`. ### Tests - Scalar: normal values, NaN, Infinity, ±0 round-trip. - Array: `bfloat16Array` with number array and with `BFloat16Array`. ## Checklist - [x] BFloat16 type with to_bits/from_bits and float32 conversions - [x] BFloat16Array with packed Uint16Array storage - [x] Wire format 2 bytes, endianness aligned with float32/float64 - [x] Type.bfloat16() and Type.bfloat16Array(); resolver and codegen - [x] Tests for scalar and array serialization/round-trip -- This is an automated message from the Apache Git Service.
