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

How to Install

1. Download the required mods and place them into your Minecraft mods/ folder:
   • Fabric API
   • Roughly Enough Items (REI) (Optional)
   • Skyblock Item List (Optional)
   • Mod Menu (Optional)
   • Not Enough Calculator (this mod)
2. Launch Minecraft using the Fabric loader
3. Open any inventory screen (chest, crafting table, etc.)
4. Start typing calculations into the search bar (REI's search bar if REI is installed, Skyblock Item List's search bar if Item List is installed, or the standalone calculator bar at the bottom of the screen)

Common Issues & Troubleshooting

Calculator search bar not showing up?

• Standalone Mode (No Search Mods Installed): Open any inventory screen (chest, crafting table, player inventory). The standalone search bar renders automatically at the bottom of your screen.
• REI Integration (REI Installed): Click inside REI's search bar to start calculating directly.
• Skyblock Item List Integration (Item List Installed): Click inside Skyblock Item List's search bar to start calculating.

Search bar position is off-screen or misplaced?

• Open /calcconfig and click the Reset button (§f§l⟲) next to the Edit GUI button.
• Alternatively, run /calcpos (or /calcconfig position) and click Reset to Default to snap the search bar back to its default position.

How do I move or drag the search bar anywhere?

• Quick In-Game Dragging: While viewing an inventory screen, hold Shift and drag the bar with Left-Click, or drag directly using Right-Click Drag.
• Interactive Editor: Run /calcpos or click Edit GUI in /calcconfig to enter the visual positioning screen with alignment guides and drag preview.

How do I disable REI or SkyBlock Item List search bar hooks?

• If you prefer having a dedicated separate calculator bar rather than typing in REI / Skyblock Item List, open /calcconfig and turn ON Force Standalone Mode.
• To disable Item List integration specifically, toggle Item List Integration to OFF in /calcconfig.

Calculator is unresponsive or not showing results?

• Make sure the search bar (REI, Skyblock Item List, or Standalone) is actively in focus (clicked into). If you click elsewhere on the screen, focus is lost.
• Check that Inline Results is enabled in /calcconfig.

How does Euler's constant `e` differ from enchanted item stacks (`2e`)?

• Standalone e (like ln(e), e^2, or 2 * e) is evaluated as Euler's mathematical constant ($e \approx 2.71828$).
• When attached directly to a number without spaces (like 2e, 10e), it evaluates as the SkyBlock enchanted item multiplier ($160$). Use 2 * e if you want two times Euler's number.

Bazaar / AH tax calculation rate is inaccurate?

• 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.

Why is division or math output rounding off decimals?

• Open /calcconfig and check your Decimal Precision setting (default is 10 decimal places). You can adjust the precision from 1 up to 50 decimal places as needed.

Calculations showing up in chat when pressing Enter?

• Running /calc <expression> prints the calculation result to your chat window, where you can click the result to instantly copy it. In search bar mode, results show directly inside the search bar.

How to copy the result or full equation?

• Press Ctrl+C inside the search bar to copy the full equation (1+1 = 2) to your system clipboard (or highlighted text if selected).
• You can also click any /calc result printed in chat to copy the full equation with instant chat confirmation.

History navigation (`Ctrl+Z` / `Ctrl+Y`) not recalling calculations?

• Make sure enableHistoryNavigation is set to true in /calcconfig. Note that calculation history is session-based and resets when joining a new world or server for a fresh start.

How do I clear my calculation history during a session?

• Run /calcclear in chat to immediately wipe your active session calculation history, or run /calchist to view recent entries.

Custom variables disappeared after restarting the game?

• Custom variables defined via /calcconfig GUI or /calcset var expr are saved permanently to config/notenoughcalculator.json. Make sure you click Save when editing variables in /calcconfig.

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.
