MankeDoMath

A calculator inside Minecraft that knows what a shulker is.

Quick sums without leaving the game: farm rates, how many shulkers a pile of
items is, how long something takes to fill.

Server-side only. Players install nothing, and vanilla clients still get
autocomplete for the command.

/m 3456 items in sb      ->  2 shulkers
/m 5sb / 2h              ->  4320 items/hour (2.5 sb/hour)
/m (16*16*64) in st      ->  256 stacks, what one chunk section is worth
/m 20st in sb            ->  0.7407 shulkers
/m 1h + 30m              ->  108000 ticks (1h 30m)

Results are only shown to whoever asked. /math share posts one to public chat.

Installation

Supports Minecraft 1.21 through 26.3. Download the jar for your Minecraft version from GitHub Releases or Modrinth, put it in the server’s mods/ folder and restart. Players do not need the mod.

Minecraft 26.3 requires Java 25, Fabric Loader 0.19.5 or newer and Fabric API for 26.3. Earlier 1.21 versions use Java 21. Replace the old jar when updating and retain config/mankedomath.conf to keep your settings.

Commands

| Command | What it does |
| — | — |
| /w4ve math <expression> | The canonical spelling |
| /math <expression> | Short alias |
| /m <expression> | Shortest alias |
| /math help | The examples above, clickable |
| /math ans | Your last result. Works inside expressions too: /math ans / 64 |
| /math share <expression> | Post the result to public chat |
| /math reload | Rereads the config (operator level 2) |

Units

| Suffix | Is | Example |
| — | — | — |
| st | stack, 64 | 3st = 192 |
| sb | shulker box, 27 stacks | 2sb = 3456 |
| dc | double chest, 54 stacks | 1dc = 3456 |
| t | ticks | 600t = 30s |
| s m h | seconds, minutes, hours | 1h = 72000t |
| b c r | blocks, chunks, regions | 2c = 32 blocks |

Longer spellings work too (stacks, shulkerboxes, items, minutes, chunks),
with or without a space after the number. sh is still accepted for a shulker
box if that is what your fingers already do.

Convert with in:

/math 3456 items in sb
/math 100 blocks in c
/math 5sb in st

Units carry through the arithmetic: 5sb / 2h is printed as a rate per hour,
and 1sb + 1h is an error.

Operators: + - * / % ^, brackets, and a lone x between numbers as
multiplication. Functions: sqrt min max abs floor ceil round log ln.
