About this addon

What it does

expr

A simple calculator that takes a Lua expression as an argument and prints the result as a system message in your chat window.

Usage: /x <expression>

Examples:

Input: /x 50 * 35

Output: 50 * 35 = 1750

Input: /x 30 / 20

Output: 30 / 20 = 1.5

Input: /x sqrt(144)

Output: sqrt(144) = 12

Compatibility

Uses very basic Lua only, and only one function from the WoW API. There is no reason this should not be compatible with every version of the game, but it has only been tested in Warlords of Draenor through The War Within, as well as Classic (1.13+)
