FAQ
Why two Korean forms (하나 and 일)?
Korean uses native numerals (하나·둘·셋…) and Sino-Korean numerals (일·이·삼…). Ages and counts favor native; numbers, money and years favor Sino. Native exists only for 1–99, so 100+ is Sino only.
Why does Japanese show two forms?
Japanese also has on-yomi (いち·に·さん…, Sino-derived) and kun-yomi (ひとつ·ふたつ…, native). Native counting exists only for 1–10 (ひとつ–とお). Romaji pronunciation is shown alongside kanji/kana.
How large a number is supported?
Up to 48-digit whole numbers. Roman numerals only cover 1–3999, and negatives prepend each language's word for "minus". Decimals are not supported.
What is the Korean amount notation?
A formal way to write money in Hangul on contracts and cheques to prevent tampering. For example 50000 becomes '일금 오만원정', keeping the '일' before 십·백·천·만.
