The numbers with a decimal writing based on the digits 0 to 9 also have a writing in whole letters. Longer and less practical, it is however used in a literary way or on certain administrative or legal writings.

To write a digit or a number in letters in English, numbers have to be written following some easy rules (with few exceptions, see below).

__Example:__ `123` is written `one hundred (and) twenty-three` (the word `and` can be omitted)

dCode's converter applies million, billion, trillion, etc. for big numbers names up to 10^63.

Words `hundred`, `thousand`, etc. are indeclinable (no plural form). There is an uninflected plural of numerals based on old English and today they did not change form.

__Example:__ `1000` : `one thousand``2000` : `two thousand` (no final `s`)

__Example:__ `3000000` : `three millions``4003002001` : `four billion three million two thousand (and) one`

By convention, numbers in literary or legal texts are represented in letters, while numbers in scientific texts are generally written in numbers.

It is mandatory to write/transcribe the numbers in letters on the checks.

dCode offers a reverse conversion tool to write numbers in digits.

Digits from 0 to 9 are written:

0 | zero |

1 | one |

2 | two |

3 | three |

4 | four |

5 | five |

6 | six |

7 | seven |

8 | eight |

9 | nine |

Numbers from 10 to 20 are written:

10 | ten |

11 | eleven |

12 | twelve |

13 | thirteen |

14 | fourteen |

15 | fifteen |

16 | sixteen |

17 | seventeen |

18 | eighteen |

19 | nineteen |

20 | twenty |

30 | thirty |

40 | forty |

50 | fifty |

60 | sixty |

70 | seventy |

80 | eighty |

90 | ninety |

100 | one hundred |

1000 | one thousand |

1000000 | one million |

1000000000 | one billion |

Hyphens are used for composed numbers inferior to `100`.

__Example:__ `21` : `twenty-one``22` : `twenty-two``88` : `eighty-eight``200` : `two hundred`

The use of hyphens can be tolerated with other numbers (ie. superior to 100). It has the advantages to delimitate the number in a sentence.

__Example:__ `One hundred and one half` for `100 + 1/2`

__Example:__ `One-hundred-and-one half` for `101 * 1/2`

The long scale and the short scale are the name given to 2 number notations (incompatible with each other). For the long scale a billion is worth a million million and the ending alternates between -ion and -iard (as used in French), while for the short scale a billion is worth a thousand million and the ending is always - ion (as used in English).

It is recommended to use scientific notation for large numbers, or even use the International System of Units prefixes for powers of 10.

There are `10` digits: `0,1,2,3,4,5,6,7,8,9` that allows writing all the numbers. Numbers are composed from 1 to n digits.

__Example:__ In the number `248`, there are three digits that are `2`, `4` and `8`.
