How it works
Q-format arithmetic worked out in the browser. The full technical description of Fixed-Point Calculator — what it does, what it is made of, and what state it is in.
The premise
A web calculator for fixed-point (Q-format) arithmetic — conversion, range, resolution and the rounding error you actually get — written because doing it by hand while writing DSP firmware is tedious and error-prone.
What is included
Q-format conversion with range, resolution and representation error shown together
Static, no backend, works offline
How it is built
Fixed-Point Calculator is built on TypeScript and Vite.
The repository is 99% TypeScript by volume — a description of what the work actually consists of rather than what it is filed under.
It carries 13 commits since Apr 2026, most recently changed in Apr 2026.
The method behind it
Every project here starts as a written specification, and the specification stays authoritative once code exists. The repository keeps a build plan with live status, an append-only decision log recording where the implementation departed from the plan, and a handoff document describing the true current state — including the parts that are not finished.
That is why a portfolio this wide is not a shallow one, and it is why this page can describe the product without overstating it.
Current state
In development. Under active work right now.
The source is public. Read it rather than taking this page for it.
