A Fast, In-Browser Decimal ↔ Balanced Ternary Converter (Handles 21M+ Entries)

Balanced ternary is a lesser-known but fascinating number system where each digit can be -1, 0, or 1. Instead of using -1, the symbol T is often used. So, for example, T10 means: (-1 × 9) + (1 × 3) + (0 × 1) = -6.

It’s a balanced system because the digits are symmetrically distributed around zero. This makes certain computations, comparisons, and even some hardware designs cleaner — and it's an interesting area of research in computer science and mathematics.

While researching Goldstein's theorem and analyzing number distributions in balanced ternary for research, I needed to convert large datasets between decimal and balanced ternary. But I couldn't find any converters online, let alone something which can convert in bulk

So... I built one!

Decimal ↔ Balanced Ternary Converter Live demo: https://vbprodev.github.io/decimal-and-balanced-ternary-converter/ Source: https://github.com/vbprodev/decimal-and-balanced-ternary-converter Key Features:

    Convert single numbers or bulk ranges (e.g., 1,1000 or T0,1T1)

    Handles 21 million+ entries using Web Workers — the UI stays smooth

    Output to clipboard for small sets, or .txt file download for large ones

    Fully responsive and accessible interface

Built with:

    HTML, SCSS, TypeScript

    Web Workers for async processing

    No backend — everything runs entirely in your browser

The aim is let you convert non standard number systems (like this one) into standard one's like base 10, base 8, or base 16
