Adds the ability to tab-complete an equation in the chat bar like so:

3+3 -> TAB -> 6

4*4= -> TAB -> 4*4=16


This can be very useful in building or crafting, as you will never need to risk mental math or need to pull out a calculator. In mods or servers like Hypixel SkyBlock, in which crafting recipes can be very expensive, this mod is a great utility.

 

 

Pressing tab with the cursor on the following equations will yield these results:

3+3 -> TAB -> 6

4*4 -> TAB -> 16

4^2 -> TAB -> 16

sqrt(16) -> TAB -> 4

4*(4+3*3) -> TAB -> 52

 

You may also put an equals sign (=) after the equation to keep it in the chat and include the solution after:

8*2= -> TAB -> 8*2=16

26+cos(0)= -> TAB -> 26+cos(0)=27

 

This calculator supports the following functions:

  • Addition (+)
  • Subtraction (-)
  • Multiplication (*)
  • Division (/)

 

  • Exponents (^, **)
  • Square root (sqrt(#))
  • Basic Trigonometry (sin(), cos(), tan())

 

3.1415926... (pi)

 

By default, solutions will be shown with comma separators (1,000) and up to 2 decimal places. This can be changed in the config file located in .minecraft/config/chatcalc.conf
