Yet Another Calculator
by wafarm
Yet Another Calculator lets players evaluate math expressions in the game's chat, with a Fabric and Quilt build for versions 1.20 – 1.21.7.
What it does
The mod adds in-game calculating functions, so a player types a calc command with an expression and gets the result back. It supports the usual operators, the constants e and pi (case-insensitive) and the trigonometric functions sin, cos, tan and deg. Results can be reused: Out[n refers to the n-th result, and a lone previous result can be recalled on its own. It runs on the client only, so servers need nothing installed. Fabric API and Fabric Language Kotlin are required, and the mod is open source under the Apache License 2.0.
Key features
Operators and constants
Standard arithmetic operators are supported, along with the constants e and pi, which are read case-insensitively.
Trigonometric functions
sin, cos, tan and deg can be used inside an expression for angle-based calculations.
Result references
Out[n returns the n-th earlier calculation, so a player can build on previous answers, for example Out[1 for the first result.
