# Project memory
- RPN calculator JS project.
- Read `.memory/state.md` for current state.
- Keep names and commands in English.
- Update memory files based on events: engine, demo, API, commands, exports, docs, or tasks.
- Core arithmetic now includes `root` for y-th roots, and `samples/calc-02/` uses it for `y√x`.
- `samples/calc-02/` in portrait mode remains the active responsive demo.
# State
- Core engine: `src/rpn-calculator.js`
- Active demo: `samples/calc-02/` portrait-only HP48GX layout; display-adjacent button row stays in 4 columns and now shares the same base button styling as the function keys
- Mode button shows the current angle mode only; selecting a mode uses a popup menu
- Public API: `push`, `pop`, `clear`, `swap`, `remove`, `edit`, `isValidIndex`, `input`, `command`, `getOperationsByCategory`, `getConstants`, `listConstants`, `setConstant`, `removeConstant`, `hasConstant`
- Config: `maxSize`, `base`, `angleMode`, `enabledCommands`
- Commands: arithmetic, stack, trigonometry, constants `pi` and `e`; arithmetic now includes `root` for y-th roots; constants can now be added or removed dynamically through the core API and the calc-02 constant menu reads from the engine
- Demo actions: keyboard focus is kept on the hidden input on desktop so typing keeps working; the keypad layout places Enter in the bottom-left, ± in the former Enter position, and Esc before Clear for safety; paste parses clipboard text as a number before pushing it to the stack; Ctrl+V is supported via the hidden input paste event; backspace is ignored when the stack is empty; operation errors are shown as an overlay bar on top of the calculator with a shorter timeout and darker red; the display button row uses a 4-column grid with a spacer cell to preserve alignment
- Exports: browser `window.RpnCalculator`, CommonJS `module.exports`
