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!
