Calc by Js802025 Mod FAQ
10 questions players actually ask, answered.
How do I start using the calculator?
Press T or / to open chat, then type /calc followed by your math expression or command. For example, /calc 2+2 will return 4. Press Enter and the result appears in green text that you can click to copy.
Can I use decimals and fractions in calculations?
Yes, the calculator supports decimal numbers in your expressions. For fractions, enter them as decimals (for example, 0.5 instead of 1/2) or use division operators like /calc 1/2.
What's the difference between /calc craft and /calc craftinv?
/calc craft tells you the raw materials needed to make a specific quantity of an item, while /calc craftinv checks your current inventory and shows how many of that item you can actually craft right now with what you have.
How do I convert my farm's production rate to items per hour?
Use /calc rates , replacing the values with how many items your farm produced during a timed test. The command automatically converts this to an hourly rate.
Do the Nether coordinate conversions work for all portals?
Yes, /calc nether and /calc overworld use the standard 1:8 coordinate ratio that applies to all Nether portals. The conversions assume normal Minecraft scaling rules.
Can I save custom math functions to reuse later?
Yes, use /calc custom add to create a reusable function, then call it by name in future calculations. Custom functions persist during your session.
How do I figure out how many items I need for a specific redstone comparator signal?
Use /calc signaltoitems , where container is the type of block (like hopper or chest) and powerLevel is the signal strength you want. It calculates the exact item count needed.
What happens if I try to craft something I don't have the recipe for?
The calculator will return an error or indicate that the recipe is unknown. Make sure you've spelled the item name correctly and that it's a valid craftable item in your game version.
Can I use this mod with other mods that add new items?
The calculator works with modded items as long as you use their correct in-game names. If a mod adds custom crafting recipes, the /calc craft command will recognize them if the mod is properly installed.
Is there a limit to how many calculations I can do?
No, you can run as many calculations as you want. The mod is lightweight and won't cause performance issues even with frequent use.
