How do I install the Library Math16 skill?

Run npx skillmds@latest add feilipu/library-math16 in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Library Math16 skill do?

math16 half-float library for z88dk: f16/f24 cores, restoring div vs NR inv, classic +test recipes need z88dk-classic sources. Use when editing libsrc math16 or measuring half-float. It is listed under Coding & Dev Tools on SkillMD.

Is Library Math16 safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Library Math16?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Library Math16 free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

File contents

Library — math16

Home under classic/newlib float trees (see libsrc/math/float/ math16 paths and --math16 on zcc). Policy mirrors math32:

Op	Algorithm
div / `asm_f16_div`	Restoring
inv / `asm_f16_inv`	Newton–Raphson

Agent rules

One major function per file; CPU copies under matching asm CPU dirs.
8085: stack-only; no EXX/IX/IY; legal (de) stores only (a/hl/post-inc).
Classic TIMER benches for math16: use z88dk-classic/*.c (parent sources may lack _Float16).
8085 math16 often also needs -lmath32_8085 for higher helpers — match classic recipes.
Suite: make -C test/suites/math test_math16.bin test_math16_8085.bin (and peers). Newlib: +rc2014 -clib=new with -lmath16 -lmath32 (mirror math32 rc2014 recipe).
Higher funcs layout: c/z80/ (sccz80 +new) and c/8085/. c/Makefile clean: only remove C-derived z80/*.asm and 8085/*.asm ($(AFILES8085)); keep hand-written cm16_sccz80_*.asm in c/8085/.

Calling vs math32

Many half API symbols are plain defc sinf16 = _m16_sinf (true DEHL) even with -D__CLASSIC — not the math32 stack-bridge trap. Still prefer map proof (sinf16 / sqrtf16 / invsqrtf16) after link. Fair n-body: math16 may keep invsqrtf16; math32 TIMER source should use 1.0/sqrt on both classic and newlib.
