`2^1200` was refused although the calculator computed it exactly: writing a result went through a float64 and refused anything outside a double's range. An exact result under the 4096-bit limit is now written from its exact value, rounded to 17 significant digits past that range, and a fractional power of such a number is computed by first bringing its base into range with square roots taken from the exact value. Results computed in float64 must still be normal doubles; past the 4096-bit limit is still refused. Disclosures: `1e-310` is answered again, reversing a call made in PR 11; a fractional power carries `math.Pow`'s rounding, which for a large base can reach the last digits shown. Model: opus-5-5

# Workflow
|
|
|
|
- branch (from `main`)
|
|
- do the work in Next Step
|
|
- move Next Step to the top of Completed Steps
|
|
- move the top item of Future Steps into Next Step
|
|
- commit (`docs/TODO.md` changes in the same commit as the work)
|
|
- merge to `main` if the branch is not protected, otherwise open a PR
|
|
- push

# Status
|
|
|
|
pre-1.0. No git tags exist. `main` is a working bot: one container image
|
|
holding the bot and the SimpleX Chat command-line client v7.0.2, a bot
|
|
profile named `calc` with a long-term address that accepts every contact
|
|
request, and exact arithmetic replies (`+ - * /`, parentheses,
|
|
decimals). The Gitea issue tracker is the authoritative list of work;
|
|
this file mirrors it.
|
|
|
|
# Next Step
|
|
|
|
Adopt the canonical `.golangci.yml` from the `prompts` repository once
|
|
it replaces `gomodguard` with `gomodguard_v2`. golangci-lint v2.12.2
|
|
warns on every run that `gomodguard` is deprecated. The file is
|
|
maintained upstream and is not edited here; done when `make lint` runs
|
|
with no deprecation warning.

# Completed Steps
|
|
|
|
- 2026-09-29 Exact results past the range of a double, such as `2^1200`,
|
|
are written to 17 significant digits instead of being refused, and a
|
|
fractional power of such a number, such as `(2^1200)^0.5`, is answered
|
|
- 2026-09-29 `POST`, `GET` and `DELETE` on a chat's webhooks, under
|
|
`/api/v1/chats/{id}/webhooks`, kept in `$DATA_DIR/webhooks.json`
|
|
- 2026-09-29 `GET` and `POST /api/v1/chats/{id}/messages`: a chat's
|
|
latest messages, and sending one
|
|
- 2026-09-29 Added the HTTP API in `internal/api`: the server on `PORT`,
|
|
the bearer credential from `API_TOKEN_FILE`, security headers and
|
|
limits, and `GET /api/v1/chats`
|
|
- 2026-09-28 Powers (`^`, also written `**`) and remainders (`%`) in
|
|
`internal/calc`, which now reads expressions with a parser of its own
|
|
in place of `go/parser`
|
|
- 2026-09-28 Moved the command tree and the `run` and `version` commands
|
|
from `cmd/simplexcalc/` into `internal/cli`; `cmd/simplexcalc/main.go`
|
|
is now a single call to `cli.Main`
|
|
- 2026-09-26 Seeded from `go-template-repo` (renamed, its HTTP service
|
|
removed) and built the bot: `internal/calc` for the arithmetic,
|
|
`internal/simplex` for the chat client process and its WebSocket API,
|
|
`internal/bot` for address setup and replies, and a runtime image on
|
|
Ubuntu 22.04 carrying the checksum-verified `simplex-chat` binary
