{{task}}

'''Ordinal numbers''' (as used in this Rosetta Code task), are numbers that describe the ''position'' of something in a list.

It is this context that ordinal numbers will be used, using an English-spelled name of an ordinal number.

The ordinal numbers are (at least, one form of them): 1st 2nd 3rd 4th 5th 6th 7th ··· 99th 100th ··· 1000000000th ··· etc

sometimes expressed as:
1^{st} 2^{nd} 3^{rd} 4^{th} 5^{th} 6^{th} 7^{th} ··· 99^{th} 100^{th} ··· 1000000000^{th} ···

For this task, the following (English-spelled form) will be used: first second third fourth fifth sixth seventh ninety-nineth one hundredth one billionth

Furthermore, the American version of numbers will be used here (as opposed to the British).

'''2,000,000,000''' is two billion, ''not'' two milliard.

;Task: Write a driver and a function (subroutine/routine ···) that returns the English-spelled ordinal version of a specified number (a positive integer).

Optionally, try to support as many forms of an integer that can be expressed: '''123''' '''00123.0''' '''1.23e2''' all are forms of the same integer.

Show all output here.

;Test cases: Use (at least) the test cases of: 1 2 3 4 5 11 65 100 101 272 23456 8007006005004003

## Factor

Factor's `math.text.english`

vocabulary provides the `number>text`

word for converting numbers to written English. It also provides the `ordinal-suffix`

word for getting the suffix for a given number, such as `th` for `12`. The bulk of this code deals with converting the output of `number>text`

to ordinal format.

from the

## Kotlin

This makes use of the code at https://rosettacode.org/wiki/Number_names#Kotlin, which I also wrote, and adjusts it to output the corresponding ordinal. Although, for good measure, the program can deal with negative integers, zero and UK-style numbers (the insertion of 'and' at strategic places, no 'milliards' I promise!) none of these are actually tested in line with the task's requirements.

## Perl

Adding zero to the input forces a numeric conversion (any identity operation would suffice).

use Lingua::EN::Numbers 'num2en_ordinal'; printf "%16s : %s\n", $_, num2en_ordinal(0+$_) for <1 2 3 4 5 11 65 100 101 272 23456 8007006005004003 123 00123.0 '00123.0' 1.23e2 '1.23e2'>;

## Perl 6

{{works with|Rakudo|2019.07.1}}

Rakudo version 2019.07.1 is updated to Unicode version 12.1. Unicode version 12.0 introduced some new numeric digits, which changed the output here a bit. This will ''work'' with earlier versions of Rakudo, but will yield slightly different results.

This would be pretty simple to implement from scratch; it would be straightforward to do a minor modification of the [[Number_names#Perl_6| Number names]] task code. Much simpler to just use the Lingua::EN::Numbers module from the Perl 6 ecosystem though. It will easily handles ordinal number conversions.

We need to be slightly careful of terminology. In Perl 6, 123, 00123.0, & 1.23e2 are not all integers. They are respectively an Int (integer), a Rat (rational number) and a Num (floating point number). (The fourth numeric is a Complex) For this task it doesn't much matter as the ordinal routine coerces its argument to an Int, but to Perl 6 they are different things. We can further abuse allomorphic and String types and role mixins for some somewhat non-intuitive results as well.

Note that the different allomorphic integer forms of 123 are evaluated on ''use'', not on ''assignment''. They can be passed around in parameters, but until they are used numerically, they retain their stringy characteristics and are distinctive, determinable through introspection. The numerics are evaluated on assignment, hence the stringified output not exactly matching the input format. The mixin role returns different things depending on what context you evaluate it under. When evaluated as a string it is 17, numerically, it is 123.

Perl 6 uses Unicode natively. If a glyph has a Unicode 'Numeric Digit' (<:Nd>) property, it is treated as a numeric digit, and may be used as one.

It is not really clear what is meant by "Write a driver and a function...". Well, the function part is clear enough; driver not so much. Perhaps this will suffice.
