# 🧮 Not Enough Calculator [![Modrinth Downloads](https://img.shields.io/modrinth/dt/notenoughcalculator?logo=modrinth&label=Modrinth&color=00AF5C&style=for-the-badge)](https://modrinth.com/mod/notenoughcalculator) [![CurseForge Downloads](https://img.shields.io/curseforge/dt/1431725?logo=curseforge&label=CurseForge&color=F16436&style=for-the-badge)](https://www.curseforge.com/minecraft/mc-mods/notenoughcalculator) [![GitHub Release](https://img.shields.io/github/v/release/Rijzzz/NotEnoughCalculator?logo=github&label=Latest%20Release&style=for-the-badge)](https://github.com/Rijzzz/NotEnoughCalculator/releases) [![GitHub Downloads](https://img.shields.io/github/downloads/Rijzzz/NotEnoughCalculator/total?logo=github&label=GitHub&style=for-the-badge)](https://github.com/Rijzzz/NotEnoughCalculator/releases) [![Discord Server](https://img.shields.io/discord/1389631948359598220?logo=discord&label=Discord&color=5865F2&style=for-the-badge)](https://discord.com/invite/asPJ4qgs8q) [![License](https://img.shields.io/badge/License-LGPL--3.0--or--later-blue?logo=gnu&style=for-the-badge)](https://github.com/Rijzzz/NotEnoughCalculator/blob/26.1.x-26.2/LICENSE.txt) **A NEU-style calculator, works completely standalone or hooks into Roughly Enough Items (REI). Type calculations directly in the search bar and get instant results.** > Inspired by [NotEnoughUpdates](https://modrinth.com/mod/notenoughupdates) calculator. Recreated for newer Minecraft versions where NEU isn't available. ![Showcase](https://cdn.modrinth.com/data/cached_images/cda48f37b923f3660dee74af920690281a87b5e2.webp) ![Showcase 2](https://cdn.modrinth.com/data/cached_images/7f8c27a134d727add7d20fb2bdd8c557f2a5f3c8.webp) --- ## What does this mod do? Type calculations directly in the search bar and get instant results! If REI is installed it uses REI's search bar, otherwise it shows its own standalone 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 --- ## Key Features

Basic Math & Functions

- Addition, subtraction, multiplication, division (`+`, `-`, `*` or `x, X`, `/`) - Exponents and modulo (`^`, `%`) - Bitwise operators: `&` (AND), `|` (OR), `~` (NOT), `<<` (Left Shift), `>>` (Right Shift), `xor(a, b)` - Factorial: `5!` = 120, `10!` = 3,628,800 - Number Literals: Binary (`0b1010` = 10), Hexadecimal (`0xFF` = 255), Octal (`0o77` = 63) - Base Conversions: `hex(255)` = `0xFF`, `bin(10)` = `0b1010`, `oct(63)` = `0o77` - Parentheses and implicit multiplication: `2(3+4)`, `(3)(4)`, `2sqrt(4)` - Smart percentage operator: `10%` = 0.1, `100 + 10%` = 110 - Constants: `pi` (3.14159...), `e` (2.71828... standalone, enchanted unit after a number) - Functions: `sqrt()`, `abs()`, `floor()`, `ceil()`, `round()`, `log()`, `ln()`, `sin()`, `cos()`, `tan()`, `rad()`, `deg()`, `min()`, `max()`, `avg()`, `pct()`, `gcd()`, `lcm()`, `clamp()`, `xor()`, `fmt()`, `hex()`, `bin()`, `oct()` - SkyBlock Tax Calculators: `bz(price)` (Bazaar net profit accounting for Bazaar Flipper perk level), `ah(price, [hrs])` / `ahbin(price, [hrs])` (AH BIN net profit after listing fee & collection claim tax)

Hypixel Skyblock Units

- Currency: `k`, `m`, `b`, `t` (thousand, million, billion, trillion) - Items: `s` (stack = 64), `e` (enchanted = 160) - Storage: `h` (shulker = 1,728), `sc` (small chest = 1,728), `dc` (double chest = 3,456), `eb` (ender chest = 2,880)

Variables (Persistent)

- `ans` – Automatically stores last calculation result - `pi` – Pi constant (3.14159265...) - `e` – Euler's number (2.71828182...) when standalone; enchanted unit (160) after a number - Custom variables with `/calcset ` (saved automatically to config & persist across restarts) - Chain calculations easily with `ans`

History, Shortcuts & Interactive Chat

- Press `Ctrl+Z` / `Cmd+Z` in the search bar to recall previous calculations (undo) - Press `Ctrl+Y` / `Cmd+Y` to redo/go forward in history - Press `Ctrl+C` / `Cmd+C` in the search bar to copy the full equation (e.g. `1+1 = 2`) to clipboard - Press `Ctrl+X` / `Cmd+X` in the search bar to cut the full equation to clipboard and clear the search bar - Partial text selection: if you highlight a specific portion of text, `Ctrl+C` / `Ctrl+X` copies/cuts only the selected snippet - Full Numpad Enter support (`GLFW_KEY_KP_ENTER`) - Interactive Chat: Click any `/calc` result in chat to copy it directly to your clipboard - View full history with `/calchist` (shows last 15 entries) - Session-based: Search history clears automatically when you leave a world/server

Customization & Settings GUI

- Open in-game settings GUI screen via `/calcconfig` or ModMenu - **Custom Variables Manager**: Dedicated tab in `/calcconfig` to easily add, edit, delete, and paginate (`<` / `>`) custom variables directly in-game - Native Minecraft hover tooltips on all settings - Bazaar Flipper Perk selector pills (`Lvl 0` = 1.25%, `Lvl 1` = 1.125%, `Lvl 2` = 1.0%) - Shorthand Results toggle to convert default calculation results to SkyBlock units (`1.5m`) - Syntax Highlighting toggle to color-code numbers, units, functions, and variables in the search bar - Configurable decimal precision (default: 10 digits) - Toggle inline results, unit suggestions, comma formatting, and history navigation - All settings persist automatically in `config/notenoughcalculator.json`

Pro Tips

### Use `ans` for quick follow-up calculations ```text 100 + 50 = 150 ans * 2 = 300 ans + 1000 = 1,300 ``` ### SkyBlock Tax Calculators (`bz` & `ah`) ```text bz(50m) = 49,375,000 (Bazaar net profit accounting for your Flipper perk level) ah(10m, 24) = 9,600,000 (Auction House BIN net profit after listing fee & claim tax) ``` ### Hexadecimal, Binary & Octal Conversion (`hex`, `bin`, `oct`) ```text 0xFF + 0b1010 = 265 (Mix base prefixes directly in math expressions) hex(255) = 0xFF (Convert decimal result to hex) bin(42) = 0b101010 (Convert decimal result to binary) ``` ### Save common values as custom variables ```text /calcset hourly 500k /calcset daily $hourly * 24 $daily * 30 = 360,000,000 (monthly) ``` ### Mix SkyBlock units & auto-formatting ```text 100m + 500k = 100,500,000 (k, m, b, t, s, e, h, sc, dc, eb multipliers) fmt(1500000) = 1.5m (Format large numbers to SkyBlock shorthand) 2dc + 5h = 18,432 (Double chest & shulker stack math) ``` ### Clipboard & Equation Shortcuts ```text Ctrl + C / Cmd + C (Copy full equation e.g. "1+1 = 2" to clipboard; copies snippet if highlighted) Ctrl + X / Cmd + X (Cut full equation to clipboard and clear search bar) Ctrl + Z / Ctrl + Y (Recall previous calculations / redo history) Ctrl + Left / Right (Jump cursor by word) Ctrl + Backspace / Delete (Delete entire word) ``` ### Chain complex calculations & parentheses ```text (100m - 50m) * 1.1 / 64 = 859,375 (per stack after markup) (5 + 3) * 2 = 16 (not 11) 2^(10-3) = 128 (not 1017) ``` ### Flexible multiplication syntax ```text 10 * 5 = 50 (traditional) 10 x 5 = 50 (also works) 10x5 = 50 (no spaces needed) ```

--- ## Support

Common Issues

- **Calculator search bar not showing up?** - **Standalone Mode (REI Not Installed)**: Open any inventory screen (chest, crafting table, inventory). The standalone search bar renders automatically at the bottom of the screen. - **REI Integration (REI Installed)**: Click inside REI's search bar at the bottom of your screen to activate calculation parsing. - **Calculator is unresponsive or not parsing inputs?** - Make sure the search bar (standalone or REI) is actively in focus (clicked into). If you click elsewhere on the screen, focus is lost. - **Bazaar / AH tax calculation rate is inaccurate?** - Open settings screen (`/calcconfig`) or ModMenu. You can configure your **Bazaar Flipper Perk Level** (`Lvl 0` = 1.25%, `Lvl 1` = 1.125%, `Lvl 2` = 1.0%) so `bz()` calculations match your exact profile perk rate. - **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 click any `/calc` result printed in chat to copy the full equation (`1+1 = 2`) 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. - **Custom variables disappeared after restarting 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`.

--- ## Why This Mod? [NEU (NotEnoughUpdates)](https://modrinth.com/mod/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)](https://modrinth.com/mod/rei) if you have it, or runs standalone if you don't. --- ## Credits Original calculator concept from **[NotEnoughUpdates (NEU)](https://modrinth.com/mod/notenoughupdates)**.
