Chinese Numerals and Financial Uppercase

Chinese numbers follow a four-digit grouping rule: 万 and 亿 work like separators, skipped places take a single 零, and trailing zeros stay silent. Type a number to get the everyday reading and the financial uppercase used on cheques and invoices, with 元, 角, 分 and 整 in the right places. The reverse direction accepts both 一二三 and 壹贰叁, so you can paste an amount written in Chinese and get the digits back.
