Calculatus
by prak132
Calculatus adds a calculator to the Minecraft chat, so a player can type a math expression and read the result without leaving the game.
What it does
Calculatus runs a calculator command in the chat. A player types calc followed by an expression, such as calc 2 + 2 3, and the result appears in the chat, rounded to the nearest hundredths digit. Expressions can include fractions, so calc 1/2 returns 0.5, and suffixes, so calc 1k returns 1,000.
The mod can also read the player's own position. An expression such as calc z+10 uses the current z coordinate, which evaluates to 0 when the player stands at z -10. This makes it a quick way to check coordinates or work out offsets while building or exploring. Calculatus is published for Fabric and Forge across the 1.8.9 – 26.2 range, so its file list covers both older and current builds.
Key features
Calculator chat command
Typing calc followed by an expression in the chat evaluates it and prints the answer.
Rounded output
Results are rounded to the nearest hundredths digit, keeping chat output short.
Coordinate-aware expressions
Expressions can use the player's position, so a value such as z+10 is computed from where the player stands.
Number suffixes
Shorthand such as 1k is read as a full number, for example 1,000.

Coordinate offsets
Builders who work from their own position can compute offsets with the calc command.
Who it’s for: Players who want a calculator inside the game chat, whether in single-player or on a multiplayer server where the client runs the mod.
