clawbot	0b9121a806	Answer exact results past the range of a double, such as 2^1200 (closes #16 ) check / check (push) Successful in 1m18s Details `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.

Answer exact results past the range of a double, such as 2^1200 (closes #16 )

check / check (push) Successful in 1m18s

Details

`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.

Exponentiation and modulo in the calculator (closes #3 )

check / check (push) Successful in 1m7s

Details

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."

A SimpleX Chat bot that answers arithmetic (closes #1 )

check / check (push) Successful in 54s

Details

Remove the template's HTTP service, database and fx wiring. Add exact
arithmetic on go/parser and go/constant, a client that runs simplex-chat
as a child process and drives its WebSocket API, and the bot, which keeps
an auto-accepting address and replies to each message. The image adds the
checksum-pinned simplex-chat v7.0.2 on Ubuntu 22.04.
