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 and public inv are restoring 1/x (NR inv bodies unlinked), force rebuild. Use when editing libsrc/math/float/math32 or A/B float divide/mul.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Library — math32

Home: `libsrc/math/float/math32/`. Docs of record: `libsrc/math/float/math32/readme.md`.
From **v2.5**, link via **`-lm`** or **`--math32`** (same IEEE flags, `-lmath32@{ZCC_LIBCPU}`). Before v2.5, classic `-lm` was genmath and newlib `-lm` was math48.

## 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`.
From **v2.5**, **`-lm` and `--math32`** are the same selection
(`-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). Before v2.5,
classic `-lm` linked genmath and newlib `-lm` linked math48. 6-byte
reruns: `--genmath` or `--math48` (sccz80 or 80cc; zsdcc still stores
4-byte IEEE). 8-byte: `--mbf64` with either compiler. ROM stays `-lmz`.

### 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 |

How to install

The exact contents, by fingerprint
mdr add feilipu/8085-skills/library-math32@sha256:a9681aeab76350a3

The line at the top of this page pins the label git:20261018.54d6d04, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
