常见问题
- 为什么要用大写金额？
- 中文小写数字容易被篡改，比如“一”改成“十”只需添一笔。大写汉字笔画复杂、难以改动，因此财务票据强制要求使用大写。
- “整”字什么时候要写？
- 金额到元为止（无角无分）时，末尾写“整”或“正”；有角无分时，角后面写“整”；分位不为零时则不写。
- 零的规则是怎样的？
- 连续的零只写一个“零”，末尾的零不写。例如 10001 元读作“壹万零壹元整”，而 10000 元是“壹万元整”。
- 金额上限是多少？
- 支持到千万亿级别。超出这个范围在实际业务中极为罕见，且会超出双精度浮点数的安全整数范围，因此做了限制。

FAQ
- Why use capital amounts?
- Lowercase digits are easy to alter — changing “一” to “十” takes one stroke. Capital Chinese characters are complex and hard to tamper with, so financial instruments require them.
- When is “整” written?
- When the amount ends at yuan (no jiao/fen), append “整” or “正”; with jiao but no fen, write it after jiao; with non-zero fen, omit it.
- What are the zero rules?
- Consecutive zeros become one “零”, and trailing zeros are dropped. E.g. 10001 → 「壹万零壹元整」, while 10000 → 「壹万元整」.
- What is the amount limit?
- Supports up to the quadrillions. Beyond that is extremely rare in practice and exceeds the safe integer range of float64, so it is capped.
