library-math32 skillA
library-math32 is agent-read markdown (skill) from feilipu/8085-skills: math32 IEEE single float library: multi-CPU layout (asm/z80, asm/8085, asm/8080, asm/vm1, asm/gbz80), products math32*.lib including ez80_z80 / gbz80 / vm1, rounding policy, div=restoring / inv=NR, force rebuild. Use when editing libsrc/math/float/math32 or A/B float divide/mul..
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 — math32
Home: `libsrc/math/float/math32/`. Docs of record: `libsrc/math/float/math32/readme.md`.
Link via **`--math32`** (`-lmath32@{ZCC_LIBCPU}`).
## 0b. Math32 multi-CPU float library (layout + policy)
Home: `libsrc/math/float/math32/`. Products: `math32.lib` (plain z80) plus
`math32_{z80n,z180,ez80_z80,r2ka,kc160,8085,8080,vm1,gbz80,…}.lib`. Link via
**`--math32`** (`-lmath32@{ZCC_LIBCPU}` — e.g. 8085 → `math32_8085`, 8080 →
`math32_8080`, vm1 → `math32_vm1`, gbz80 → `math32_gbz80`, ez80_z80 →
`math32_ez80_z80`; no separate `--math32_8085` flag).
### Layout
| Tree | Role |
|------|------|
| `asm/` | 8080-compatible shared files (const, coeff, load, classify). Classic: `newlibfiles_common_asm.lst` |
| `asm/z80/` | Z80-family cores; shared by z80n/z180/ez80_z80/r2ka/… when the lst points here |
| `asm/8085/` | Stack-only 8085 cores (no EXX / IX / IY); extended opcodes + synthetics. After `rl de`, test exp with `inc d`/`dec d` — RDEL does not write Z. CPU-specific `f32_f2long` / `f32_l_ldexp`. Classic `ftoa`/`ftoe`/`ftog` in this dir (`ld de,sp+n`, LHLX/SHLX, `rl de`). Do **not** write `ld hl,sp+n` (LDSI+`ex`; bad for `sp-32`) |

How to install
mdr add feilipu/8085-skills/library-math32@git:20260918.95c4588mdr add feilipu/8085-skills/library-math32@sha256:d348cffa3eec1418Pin 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.
