The calculator now takes `^` (or `**`) for powers and `%` for modulo. Powers bind tighter than a sign on their left and group to the right, so `-2^2` is `-4` and `2^3^2` is `512`; `%` sits with `*` and `/` and takes the sign of the divisor. A small parser of our own replaces `go/parser`, which cannot express `^`; `go/constant` still computes. A whole-number exponent is exact; a fractional one is computed in float64. Every number is held as a fraction under 4096 bits, and a float64 result must be a normal double, so one message cannot stall the bot; anything else gets "That needs a number too large or too small for me." Disclosure: tiny values below about 2.2e-308, which `next` answered, are now refused. 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
|
|
|
|
- 2026-09-28 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
|
