Not Enough Calculator

🧮 Not Enough Calculator

A NEU-style calculator that works standalone or inside Roughly Enough Items (REI) & Skyblock Item List search bars. Type calculations directly in the search bar and get instant results.

Inspired by NotEnoughUpdates calculator. Recreated for newer Minecraft versions where NEU isn't available.

---

What does this mod do?

Type calculations directly in the search bar and get instant results! Works inside Roughly Enough Items (REI)'s search bar, Skyblock Item List's search bar, or completely Standalone with its own bar at the bottom of inventory screens. If you played with NEU on older versions, you already know how this works.

Example: Type 100m - 50m in the search bar → See = 50,000,000 instantly

FAQ & Troubleshooting

Where can I use the calculator?

• Standalone Bar: Available at the bottom of inventory screens (moveable anywhere with Shift+Drag or Right-Click Drag).
• Roughly Enough Items (REI): Directly inside REI's item search bar.
• SkyBlock Item List: Directly inside the SkyBlock Item List search bar.
• Chat: Anywhere using /calc <expression>.

How do I move or resize the standalone search bar?

• Hold Shift and left-click drag (or right-click drag) the search bar to move it anywhere on your screen.
• You can also run /calcpos or open /calcconfig and click Edit GUI to interactively drag the bar. Click the reset button (§f§l⟲) to restore the default position.

Can I use this without Roughly Enough Items (REI)?

• Yes! As of v2.7.0, REI is completely optional. If REI is not installed, Not Enough Calculator operates in standalone mode automatically.

How do I copy my answers?

• In search bars, press Ctrl+C with no selection to copy the full equation (100m - 25m = 75m).
• In chat, simply click on the highlighted result text to copy it directly to your clipboard.

How do I adjust Bazaar tax calculations to match my account?

• Open the settings screen (/calcconfig). Under Bazaar Flipper Perk, select your account's Community Center perk level (Lvl 0 = 1.25%, Lvl 1 = 1.125%, Lvl 2 = 1.0%) so bz() calculations match your profile's exact tax rate.

Can I use custom variables inside complex expressions or other variables?

• Yes! You can reference custom variables anywhere in equations, including inside function calls (e.g. sqrt($mysize)), with custom variables (e.g. $profit - $cost), or combined together (e.g. $profit * $tax).

How do I reset my custom variables or config?

• You can manage or delete variables individually in the /calcconfig GUI under the Custom Variables tab. To reset everything to default, delete config/notenoughcalculator.json in your .minecraft folder while the game is closed.

Bitwise operations or radix outputs not behaving as expected?

• Hexadecimal (hex()), Binary (bin()), and Octal (oct()) functions operate on integer values. Floating-point numbers are rounded to nearest integers when performing bitwise operations (&, |, ~, <<, >>, xor).

Why does typing a single number like 64 or 6912 not show calculator results in the search bar?

• Standalone plain numbers without operators or units are treated as item count or item ID searches in REI and SkyBlock Item List so normal item searching is not interrupted. To calculate or view unit equivalents for raw numbers, type an expression (e.g. 6912+0, 2dc, 1sc) or run /calc 6912 in chat.

How does radix literal formatting work (0xFF, 0b1010, 0o77)?

• When calculating purely with radix literals, the calculator preserves the original base format on output (0xFF = 0xFF, 0b1010 = 0b1010, 0o77 = 0o77). To convert to decimal, use standard math (e.g. 0xFF + 0 = 255, 0b1010 + 0 = 10). To convert any decimal into a radix format, use hex(255), bin(10), or oct(63).

---

Why This Mod?

NEU (NotEnoughUpdates) had a great calculator built into its search bar. NEU doesn't exist for newer Minecraft versions though, so this mod fills that gap. Works with Roughly Enough Items (REI), Skyblock Item List, or runs completely standalone.
