Mineculator
by Vital1kS
Mineculator is a Fabric utility that evaluates arithmetic typed into the chat, so players can work out a sum without leaving the game.
What it does
Typing an expression that starts with a symbol in chat sends it to the calculator, which combines numbers with several operators in one line. Operators carry priorities: a higher value means the operation is done earlier, and operations of equal priority are evaluated from left to right. Brackets override that order and are calculated first. Decimal values can be written with a dot or a comma.
Errors are reported back in chat. A message explains where an expression is incomplete, where brackets are used incorrectly, which symbols or letters do not belong in an expression, and other problems with the input, so the player can find the mistake and retype it. The mod is a Fabric build for 1.20.1 and for 1.21.4 – 1.21.10, and it is released under All rights reserved, so the code is not open source. Snapshot builds are not part of the release list.
Key features
Chat expressions
Expressions are typed into the chat window and begin with a symbol, with no separate screen or command to open.
Operator priority
Operators are ranked by value, so multiplication and division bind more tightly than addition and subtraction.
Bracket grouping
Brackets are evaluated before any other operation, allowing a player to change the order of a calculation.
Decimal input
Floating-point numbers can be written with either a dot or a comma as the separator.
Error messages
Input mistakes produce a chat message that names the problem, such as incomplete expressions or unexpected letters.

How it compares
Chat Calcus is a Fabric mod for 1.20.4 – 1.21.1, released under the MIT License and open source, and it runs on the client alone. MathMod is a Fabric mod for 1.21.4, also MIT and open source, and it likewise needs only the client. Mineculator differs because either side can run it and neither needs it, and its license is All rights reserved, so its code is not open source.
