CheckStive

A simple Lua program that checks if numbers are positive, negative, or zero. That's it!

Quick Start

Just want to use it?

lua cli.lua

Enter a number and it tells you what it is. Type exit to quit.

Want to use it in your code?

local checkstive = require("checkstive")

checkstive.isPositive(5)   -- true
checkstive.isNegative(-10) -- true
checkstive.isZero(0)       -- true

local state = checkstive.getState(42)
-- state is now "positive"

What's inside?
