3. #3# `gno.land/r/moul/x/daily/romannumdemo/v0` Interactive gnoweb **demo of the [`p/moul/x/daily/romannum`](https://github.com/moul/gno-contracts/tree/main/p/moul/x/daily/romannum/v0) Roman-numeral library** — it renders a table of worked examples and interactive integer→Roman and Roman→integer conversions. It has no conversion logic of its own. ## Render paths - `:` / root — a table of example conversions (1, 4, 9, 40, 90, 400, 900, 2024, 3999, …). - `:/<n>` — integer → Roman, e.g. [`:/2024`](https://gno.land/r/moul/x/daily/romannumdemo/v0:2024) → `MMXXIV`. - `:/r/<roman>` — Roman → integer, e.g. [`:/r/MMXXIV`](https://gno.land/r/moul/x/daily/romannumdemo/v0:r/MMXXIV) → `2024` (case-insensitive). <!-- BEGIN GNOCONTRACTS FOOTER (generated by `make readmes`; do not edit below) --> --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
