🔢 Simple Calculator

An intuitive calculator with some handy variables. To see a list of variables run /calc variables.

Supported Operators

Symbol(s)	Syntax	Operation
+	a+b	Addition
–	a–b	Subtraction
* , × , ∙	a*b	Multiplication
/ , : , ÷	a/b	Division
^	a^b	Exponentiation (power)
!	n!	Factorial
#	a#b	Modulo
%	x%	Percentage
^^	a^^b	Tetration
√	√x	Square root
∛	∛x	Cube root
∜	∜x	Fourth root

CalcMod has some more advanced functions and variables that can be used within expressions in this spreadsheet.

Usage: /calc <expression>

📦 Storage Utils

When given a rate of items per hour (expressions allowed), returns the minimum number of item sorters needed to sort in time.
Additional input for multiple times hopper speed sorters, and a separate command for Allay based non stackable sorters.

Usage: /calc storage <itemsPerHour>
Usage: /calc storage <timesHopperSpeed> <numberOfItems>
Usage: /calc allaystorage <itemsPerHour>

🛠️ Crafting Utils

When given an amount of a recipe to craft (expressions allowed), returns all the items required to craft that quantity of the recipe.

(CalcMod 1.3.2+) The optional depth argument specifies how many levels of recursive crafting to perform on the recipe. Default depth is 1.

(Minecraft 1.21.3+) Due to Minecraft's crafting system updates, CalcMod's craft command can now only use recipes unlocked in the user's recipe book in single player mode.

Usage: /calc craft <item> <amount>
Usage: /calc craft <item> <depth> <amount>

🌐 Portal Linking Coords

When given a block position, returns the dimension in the command's corresponding coordinates. If no coordinates are given, command assumes current player position.

Usage: /calc nether <x> <y> <z>
Usage: /calc overworld <x> <y> <z>

🌾 Farm Rates Calculator

When given an amount of items and a farm run time in seconds (expressions allowed), returns the items per hour of the farm.

Usage: /calc rates <numberOfItems> <seconds>

🎲 Generate Random Number

When given a maximum and/or minimum value, returns a random number between those values (inclusive). If just a maximum value is entered, picks a random number from 0 to the max value (inclusive).

Usage:/calc random <max>
Usage: /calc random minmax <min> <max>

💪 Comparator Power Level Finder

When given a container and a desired comparator power level (expressions allowed), returns the number of items needed to achieve that power level.

Usage: /calc signaltoitems <container> <powerLevel>

🐷 Piglin Bartering Utils

Calculates the average number of gold ingots needed to barter for a specific quantity of a desired item (togold), or the average number of a desired item received when bartering a specific number of gold ingots (toitem).

Usage: /calc barter togold <numberOfItems> <item>
Usage: /calc barter toitem <amountOfGold> <item>

🧭 Travel Distance Evaluator (New!)

When given two block positions, returns the distance between them. If only one position is given, uses player's location. The 3D mode provides distance including height (y coord).

Usage: /calc dist <x1> <y1> <z1>
Usage: /calc dist <x1> <y1> <z1> <x2> <y2> <z2>
Usage: /calc dist 3d <x1> <y1> <z1>
Usage: /calc dist 3d <x1> <y1> <z1> <x2> <y2> <z2>

🧮 Custom Functions

Custom functions are reusable commands that perform a specific computation. Custom functions can be run in any number field formatted with the function name and its parameters in parentheses functionName(<param1>, ...,<paramN>).

Creating a Function:
Custom functions can have any number of parameters, specified in [square] brackets when adding a function.

⚠️ Using any numbers, special characters, or variables in a parameter may result in a broken function.

e.g. /calc custom add blockstoingots [numBlocks]*9

/calc blockstoingots(72)

Usage: /calc custom add <functionName> <function>
Usage: /calc custom run <functionName> <input>
Usage: /calc <functionName>(<parameters>)
Usage: /calc custom list
Usage: /calc custom remove <functionName>

➡️ Converters:

Shulker Boxes ↔ Items

When given an amount of full shulker boxes (expressions allowed), returns the number of items they contain, or vice versa.

Usage: /calc itemtosb <numberOfItems>
Usage: /calc sbtoitem <numberOfSbs>

Items ↔ Stacks:

When given an amount of stacks (expressions allowed), returns the number of items in those stacks, or vice versa.

Usage: /calc itemtostack <numberOfItems>
Usage: /calc stacktoitem <numberOfStacks>

Seconds → Hopper Clock Items

When given a time in seconds (expressions allowed) returns the number of items to put in a hopper clock to achieve that time.
Uses formula and hopper clock from hoppertimer.net.

Usage: /calc secondstohopperclock <seconds>

Seconds → Repeater Delay

When given a time in seconds (expressions allowed), returns the number of repeaters and their delays to achieve that time.

Usage: /calc secondstorepeater <seconds>

❎ Variables

Variables can be used inside commands in any number field. They act as shortcuts instead of having to remember that "a double chest full of 16 stackable items is 864."
If no stack size is given, variables default to the contextualized stack size in each command.

Constant Variables

Name	Value
dub	3456 (default)
dub64	3456
dub16	864
dub1	54
sb	1728 (default)
sb64	1728
sb16	432
sb1	27
stack	64 (default)
stack64	64
stack16	16
stack1	1
min	60
h	3600

x	player x coord
y	player y coord
z	player z coord
health	player health
