sqrtnix

Sqrtnix is a cross-platform numerical library focused on efficient computation of square roots and related mathematical routines. Its design targets low latency and high throughput across a range of devices, from embedded systems to high-performance computing environments. The project emphasizes portability, a stable API, and predictable numerical behavior to fit into existing math stacks.

Features include support for single- and double-precision square roots, with attention to accuracy and performance. Sqrtnix employs a combination of fast initial approximations and iterative refinement, commonly using Newton-Raphson or similar methods, to deliver results quickly while maintaining controlled error bounds. The library provides robust handling of edge cases such as NaN, Inf, signed zero, and denormal numbers when enabled.

Implementation and ecosystem: the core is written in C with a minimal, well-documented API. Language bindings exist for Python and Rust, and there are experimental bindings for JavaScript via WebAssembly. Sqrtnix is released under an open-source license and includes unit tests, benchmarks, and a reference implementation to aid verification and portability. The project follows a semantic versioning scheme and distributes both source code and prebuilt binaries.

Architecture: Sqrtnix separates the core math engine from platform-specific backends, allowing SIMD optimizations on x86 (SSE/AVX) and ARM (NEON). A portable fallback path ensures functionality on platforms without SIMD support. The library aims for deterministic results across platforms and reproducible performance characteristics, aiding cross-platform development and testing.

Usage and status: suitable for performance-critical code, graphics pipelines, and numeric simulations. The project is maintained by an open community with ongoing work on precision modes, SIMD backends, and broader platform support, with regular releases and compatibility updates.
