QuickCalc
by DeltaNedas
QuickCalc is a Fabric client mod that evaluates arithmetic typed into the chat box and replaces the expression with its answer.
What it does
Typing a sum such as 2 + 2 into chat and sending it swaps the expression for the result, 4, before the message is posted. QuickCalc works only on the client as a Fabric mod covering Minecraft 1.16.5 – 1.18, and its newest file, targeting 1.18, was posted on 2021-12-05, copying the calculator logic from OpenModsLib.
Key features
In-chat calculation
Arithmetic typed into the chat box is evaluated when the message is sent.
Result replacement
The expression in the message is replaced by its numeric answer, so the sent text reads 2 + 2 as 4.
Client-only operation
The calculator runs on the player's client, so servers do not need to install anything for it to work.
Compatibility
