FAQ
- What is compact notation?
- Compact notation shortens large numbers using suffixes like K (thousands), M (millions), and B (billions). For example, 1,200,000 becomes 1.2M.
- Why are Binary/Octal/Hex only for integers?
- Base conversions require whole numbers. If you enter a decimal like 3.14, these fields show 'N/A (integers only)'.
- Which currencies are supported for formatting?
- USD, EUR, GBP, JPY, and CNY are supported, each with locale-appropriate formatting.
