Bigger, Faster, Stronger Types

https://cppalliance.org/matt/2025/07/14/Matts2025Q2Update.html

Progress on Boost libraries: int128 beta‑ready and integrated into an IEEE‑754 decimal type with a 256‑bit backend, giving >100 % speedups. Boost.Math GPU support refined; Boost.Multiprecision adds a double‑double backend for precision with lower cost.

  • Boost.RunTimeServices: The Glue for Optional Runtime Features
    Link
    Compile‑time macros are replaced by runtime services for optional features like compression, allowing services to be installed and queried at execution, producing smaller binaries and one library version, while challenges of linking and overhead are noted.

  • Speed and Safety
    Link #Decimal
    CUDA support is added to Boost int128 for host and device use. Device from_chars/to_chars are provided by Boost.Charconv, and Boost.Decimal will gain CUDA later. Verification is used by Boost.Safe_Numbers for safety and error check with CUDA reporting.
  • Decimal Goes Back to Review
    Link #Decimal
    The Decimal library is re‑entering Boost review (Oct 6‑15). Updates include renamed types/headers, simplified constructors, IEEE‑754 rounding, Antora docs, fmt and CMake support, and resolved review issues; hardware decimal and CUDA support are planned.
  • Moving Boost forward: Asio, coroutines, and maybe even modules
    Link #Decimal
    Boost updates include coroutine-based Asio usage, a prototype for native C++20 module support with CMake integration, performance benchmarks and enhancements for Boost.MySQL, Boost.Decimal integration, and plans for a Postgres library.
