x07-ext-math — v1 native backend (normative guidance)

This package is intended to be deterministic across platforms by pinning the native implementations used for:

  • float-to-string
  • string-to-float
  • libm transcendental functions

Recommended pinned components:

  • OpenLibm (portable, standalone libm)
  • Ryu (shortest round-trip float-to-string)
  • fast_float (exact rounding string-to-float)

The toolchain should vendor these sources at pinned commits and build them deterministically.

The current in-repo native backend and its build/CI wiring are described in the native backend page.
