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 - Config:
maxSize,base,angleMode,enabledCommands - Commands: arithmetic, stack, trigonometry, constants
piande; arithmetic now includesrootfor y-th roots - 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
