About this project
What does StackCalc add?
Stack Calc
A calculator that thinks in stacks.
You know the moment. You need enough concrete for a build, or you're pricing a trade, and you end up with a random number like 4712 items. How many shulker boxes is that? Stack Calc answers instantly, right in game.
Press = and type anything. The result is broken down into shulker boxes, stacks and leftover items as you type.
64 * 8 + 30 = 542 = 3 stack + 30 item
5h + 12 = 8652 = 5 shulker + 4 item
Features
- Full expression parser.
+ - * / % ^, parentheses, and implicit multiplication like2(3+4). - Unit suffixes. Type
5sinstead of320. See the table below. - Live breakdown. Shulker boxes, stacks and leftovers, colored so you can read them at a glance.
- Syntax highlighting. Numbers, operators, parentheses and suffixes each get their own color. Invalid characters turn red before you even finish typing.
- Stack size toggle. Switch between 64, 16 and 1 for items that do not stack fully.
- Copy to clipboard. Press Enter and the result is ready to paste.
