MI-84 Calculator

0.3 - 2026-08-04

Added

• Persistent real L1–L6 and user-named lists, a TI-84-style STAT→Edit table, list literals, and LIST NAMES/OPS/MATH operations including sequences, sorting, Fill, and summaries.
• Persistent TABLE SETUP and graph TABLE views with Auto/Ask independent and dependent values, signed row scrolling, editable Y headers, and visible error cells.
• Persistent FORMAT controls for rectangular coordinates, trace readouts, grid, axes, labels, and expression visibility.
• Persistent STAT PLOT configuration for three fixed-color plots, including Scatter and Line graph rendering with selectable marks and clipped line segments.

Changed

• Xres now accepts only exact integer values from 1 through 8, matching the TI-84 range.
• The mod is declared client-only in Fabric metadata.
• Public and maintainer documentation now distinguish available list, table, format, and plot features from distribution plots, polar graphing, statistics, and other deferred systems.

Fixed

• A full 999-element list no longer exposes or attempts to commit an invalid 1,000th element.
• Complex division remains stable when finite operands have extremely large or small magnitudes; genuine overflow and underflow now produce explicit calculator errors.
• seq( substitutes only the selected scalar variable token and no longer corrupts identifiers such as Ans, logBASE, graph variables, or list names.
• Insert mode now uses a blinking underscore cursor while preserving the character beneath it.

Known limitations

• Histogram, both box-plot types, and relative-frequency plot configuration are visible but remain marked [deferred]; Scatter and Line are the rendered STAT PLOT types in 0.3.
• Polar/sequence graphing, graph CALC, matrices, statistics calculations, programs, apps, linking, and several dependent menu rows remain unavailable.
• The overlay can be clipped at unusually small GUI dimensions and is not clamped after resizing.
• Calculator position is retained between inventory sessions but not across game restarts.
• Recalling a history input longer than the 31-character editor limit fails without an on-screen error.
