CalcMod is a calculator in your Minecraft chat with extra features to determine farm rates, generate random numbers, convert between Overworld and Nether coordinates, and a bunch of other nerdy things. CalcMod is more catered to technical Minecraft players, but is useful to all. it's lightweight and unintrusive. It would be a good fit for ATM because very helpful for any minecraft calculations!
