en-US, en-GB, de-DE, fr-FR, pt-BR, ja-JP, zh-CN, and ar-SA — covering common differences in thousands separators, decimal marks, and digit grouping conventions.
Decimal formats a plain number with locale-appropriate separators. Currency adds a currency symbol and follows that currency's typical decimal convention. Percent multiplies the value by 100 and appends a % sign.
en-US uses a comma for thousands and a period for decimals (1,234,567.89), while de-DE swaps them (1.234.567,89) — the tool applies each locale's actual formatting convention.
Scientific notation (e.g. 1.235e+6) is compact for very large or small numbers in technical contexts. Engineering notation restricts the exponent to multiples of 3 (e.g. 1.235 × 10^6), aligning with SI unit prefixes like kilo, mega, and giga.
Yes — set the minimum and maximum decimal digits independently (0-20), which controls both padding with trailing zeros and rounding of longer decimals.
