VortexCalc

VortexCalc is a fast, practical scientific calculator for Windows built with Electron + React.

It focuses on typing real expressions (not just button tapping), plus a few tools you actually use day-to-day (plot + unit conversion), wrapped in a “glassy / 3D” UI that stays keyboard-friendly and accessible.

Download (recommended)

1. Open the GitHub Releases page for this repository.
2. Download the latest VortexCalc-Setup-<version>.exe.
3. Run the installer.

If Windows SmartScreen appears, click “More info” → “Run anyway”.

Features

• Expression input (type full formulas)
• Variables (example: x = 5, then x * 10)
• ans for the last result
• Memory keys: MC / MR / MS / M+ / M-
• DEG/RAD toggle for trig
• Plot f(x) in the Plot tab
• Unit converter (length, mass, temperature)
• Quality-of-life UI:
  • Examples you can click to load
  • Help modal with shortcuts (Ctrl+/ or F1)
  • Optional “Sci” keypad expansion

What it’s used for

• A faster “calculator + notes” workflow: type the full formula you want, not just button taps
• Quick trig/log/roots/factorials during coding, studying, or work
• Checking a function visually before using it
• Simple unit conversions without opening a browser

How to use

Calculator

1. Type an expression in the input box.
2. Press Enter or click = to evaluate.
3. Use ans to reference the last result.
4. Use variables by assigning them, e.g. x = 3, then use x * 10.

Memory keys

• MC: clear memory
• MR: recall memory into the input
• MS: set memory to the current result
• M+: add current result to memory
• M-: subtract current result from memory

Plot

• Go to the Plot tab, enter f(x) (example: sin(x)), pick xMin/xMax, then click Plot.

Convert

• Go to Convert, choose category and units, type a value, and the converted value updates automatically.

Shortcuts

• Enter: evaluate
• Esc: clear input + output
• Ctrl+Backspace: clear input
• ArrowUp: load latest history item
• Ctrl+L: focus input
• Ctrl+/ or F1: open/close help

Supported input (examples)

• sin(30) + 2^3
• sqrt(2) * 10
• x = 5
• ans * 2
• fact(10)
• log10(1000)

Notes

• Trig functions (sin, cos, tan, asin, acos, atan) follow your DEG/RAD toggle.
• Use ln(x) for natural log and log10(x) for base-10 log.
• Use fact(n) for factorial (best with integers).

Requirements (for developers)

• Node.js (LTS recommended)
• npm

Install & run (dev)

npm install
npm run dev

Build the Windows .exe (installer)

npm run dist

The installer will be created under the release/ folder.
