In Cantonese, numbers can be interpreted as a series of digits. From decimal to ten-thousandfold, each digit has a corresponding character. To read out the number, read the number of the value of the digit followed by the value of the digit. For example, the number four-hundred and seventy-nine (479) has three digits: four hundreds (四百, read as sei-bāak), seven tens (七十, read as chāt-sahp) and nine (九, read as gáu). The number is written as 四百七十九 and is read as sei-bāak-chāt-sahp-gáu. The word "and" in "four-hundred and seventy-nine" is omitted.
Any digit in zero followed by a digit which is not zero is replaced by the character 零 (read as lìhng). For example, the number one-thousand and one (1001) is read as yāt-cin-lìhng-yāt.
The number eleven (11) is literally one-ten and one but the character "one" in "one ten" is usually omitted. The same case applies to twelve to nineteen.
The number two sometimes becomes 兩 (read as loeng) rather than 二 (read as yih). Examples include:
- 兩性 loeng-sing the two sexes
- 兩文三語 loeng-man-sāam-jyu two written languages and three spoken languages
- 一國兩制 yāt-gwok-loeng-zai one country two systems
Generally, two is 兩 when:
- it is used for counting (e.g. two apples, two people, two houses)
- it precedes units more than or equal to a thousand
two is 二 in:
- certain set expressions (such as idioms)
- numbers less than or equal to a thousand
One through Ten
- 〇 (零) lìhng zero 0
- 一 (壹) yāt one 1
- 二 (貳) yih two 2
- 三 (叁) sāam three 3
- 四 (肆) sei four 4
- 五 (伍) ng five 5
- 六 (陸) luhk six 6
- 七 (柒) chāt seven 7
- 八 (捌) baat eight 8
- 九 (玖) gáu nine 9
- 十 (拾) sahp ten 10
Parenthesized entries are the complex forms, which are used mainly in notarized, official documents. An exception is zero wherein the complex form is more widely used.
