为什么 “one two” 会报错？Why is "one two" rejected?
两个个位数、两个整十数或重复的 hundred/thousand 连在一起（one two、thirty forty、one hundred two hundred）不是一个数的标准读法，直接相加会得出错误结果，所以会提示顺序不对。年份式的读法（twenty twenty = 2020）也不支持，请写成 two thousand twenty。Two units, two tens or a repeated hundred/thousand in a row (one two, thirty forty, one hundred two hundred) is not a valid way to read one number, and silently adding them would give a wrong value, so the tool reports the order instead. Year-style readings (twenty twenty = 2020) are not supported either — write two thousand twenty.
支持哪些写法？Which forms are supported?
英文：zero 到 quintillion，可带 and、连字符、a hundred、minus，小数用 point 逐位读（point two five）。中文：小写（一二三）、大写（壹贰叁）、两、〇/零，单位十百千万亿，口语“二百五”=250、“三万五”=35000，逐位读的“二零二四”=2024，以及“3万5千”这样的阿拉伯数字混写。English: zero to quintillion with and, hyphens, "a hundred", minus, and decimals read digit by digit (point two five). Chinese: everyday and financial numerals (一二三 / 壹贰叁), 两, 〇/零, units 十百千万亿, colloquial 二百五 = 250 and 三万五 = 35000, digit-by-digit 二零二四 = 2024, and mixed forms like 3万5千.
能处理多大的数？How large can numbers be?
用 BigInt 精确计算，不会出现科学计数法或精度丢失，例如 nine quintillion = 9,000,000,000,000,000,000。It uses exact BigInt arithmetic — no scientific notation or rounding — e.g. nine quintillion = 9,000,000,000,000,000,000.
“3.5万”可以吗？Does "3.5万" work?
暂不支持“小数 + 单位”的混写，请写成“3万5千”或“三万五千”。Decimal-plus-unit forms are not supported yet; write 3万5千 or 三万五千 instead.
