library-math16 skillA
library-math16 is agent-read markdown (skill) from feilipu/8085-skills: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Library — math16
Home: `libsrc/math/float/math16/`. Docs of record: `libsrc/math/float/math16/README.md`.
Link via **`--math16`** (`-lmath16@{ZCC_LIBCPU}`). Adjunct: no conflict with
math32 / math48 / am9511. **No** printf / scanf / dtoa on the math16 product.
Classic products match math32’s CPU set: `math16.lib` plus
`math16_{ixiy,z80n,z180,ez80_z80,r2ka,r4k,r6k,kc160,8085,8080,gbz80}.lib`.
8080 / 8085 / gbz80 higher via **sccz80 only**.
### Layout
| Tree | Role |
|------|------|
| `asm/` | 8080-compatible shared files (specials, coeff). Classic: `newlibfiles_common_asm.lst` |
| `asm/z80/` | Z80-family cores; z80n/z180/ez80_z80/r2ka/kc160 assemble this list. Unrolled 11×11 / 16×16 is `IF __CPU_Z80__` only; others call `l_mulu_32_16x16`. `asm_f16_f48` is Z80-only |
| `asm/8085/`, `asm/8080/`, `asm/gbz80/` | Stack-only CPU cores (same one-op-per-file map) |
| `c/z80/`, `c/8085/`, `c/8080/`, `c/gbz80/` | Higher functions. 8080/8085/gbz80 via **sccz80 only**. Binary-op bridges that use EXX live in `c/sccz80` (z80) or `c/<cpu>` (8080/8085/gbz80). No 8085 `fma` |

How to install
mdr add feilipu/8085-skills/library-math16@git:20260918.95c4588mdr add feilipu/8085-skills/library-math16@sha256:829a10df36269c91Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
