MI-84 Calculator

The Minecraft Instruments 84: an all-in-one calculator for blocky calculations!

Version 0.3 targets fabric 1.21.1 and is client-side only. It’s the latest development version.

Dependencies

• Fabric API
• Fabric Language Kotlin

Use

Open an inventory and click the X button at the bottom-left or the H Hotkey to show or hide the calculator.

The default keybindings work only while an inventory is open:

• N — reset the calculator position
• H — toggle calculator visibility
• K — toggle the inventory X button

All three bindings can be changed under Controls.

Version 0.3 highlights

• Scientific and rectangular-complex calculation with persistent history and scalar variables.
• Structured fractions, roots, combinatorics, TEST/LOGIC, partial ANGLE and MATH-family menus.
• Persistent real lists, named lists, STAT→Edit, and LIST NAMES/OPS/MATH operations.
• Y=, Window, trace, zoom, graph TABLE/TBLSET, and renderer-backed FORMAT settings.
• Persistent STAT PLOT configuration with Scatter and Line rendering.

Current limitations

• Input uses the calculator’s on-screen keys; computer-keyboard expression entry is not supported.
• Polar and sequence graph modes, graph CALC tools, matrices, programming, and statistical calculations remain deferred.
• Statplot Histogram, box-plot, and relative-frequency settings are visible as [deferred]; only Scatter and Line currently render.
• The overlay may be clipped at unusually small GUI sizes
