Some Chinese characters used as complex and formal numerals have other uses as well, possible as heteronyms. See Standard numbers for more information. They are necessary because, since normal Chinese characters are so simple, a forger could easily change 三十 to 五千 with just three strokes. The complex forms are known in English as banker's anti-fraud numerals, in Chinese as 大寫 (simplified Chinese: 大写 Hanyu Pinyin: dàxiě which is the same term for "capital letter"). An exception is zero the complex form is much more widely used than a casual circle. The parenthesized entries are the complex and formal forms, which are used mainly in notarized, official documents, and when writing checks.
