| CPU | FPU | Math Behavior |
|---|---|---|
| **68040** (full) | ✅ Built-in | Basic FPU ops in hardware. Transcendentals trapped → 68040.library |
| **68LC040** | ❌ No FPU | ALL FPU ops trap → needs 68040.library + SoftIEEE or full emulation |

## Third-Party Replacement Libraries
The Amiga's library system allows **drop-in replacements** — you simply copy an optimised `.library` to `LIBS:` and it supersedes the ROM version. Several third-party packages exploit this for dramatic speedups.

4. **68LC040/060 crashes** — Code that works on full 68040 Gurus on LC variants. Install `SoftIEEE` or equivalent FPSP to trap Line-F exceptions from unimplemented FPU instructions.
5. **HSMathLibs CPU mismatch** — Installing the 040-optimised libraries on a 060 (or vice versa) can cause incorrect results or reduced performance. The pipeline timings are architecturally different.
