![Task](http://static.miraheze.org/rosettacodewiki/thumb/b/ba/Rcode-button-task-crushed.png/64px-Rcode-button-task-crushed.png)
You are encouraged to solve this task according to the task description, using any language you may know.
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:
1st 2nd 3rd 4th 5th 6th 7th ··· 99th 100th ··· 1000000000th ···
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 short scale numbering system (i.e. 2,000,000,000 is two billion) will be used here. wp:Long and short scales
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'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.

J
Here, we follow J's best practice for ordinal numbers, which is that 0 is first and 1 is second. This emphasizes the distinction between cardinal numbers like 0 and ordinal numbers like first, accurately represents array indices, and neatly captures a variety of related linguistic issues.
Also, we use definitions from the number names task and the N'th task:
ord=: {{
((us,suf)1+y) rplc ;:{{)n onest first twond second
threerd third fiveth fifth eightth eighth
}}-.LF
}}
Examples:
ord 0
first
ord 1
second
ord 2
third
ord 3
fourth
ord 4
fifth
ord 5
sixth
ord 11
twelveth
ord 65
sixty-sixth
ord 100
one hundred first
ord 101
one hundred second
ord 272
two hundred seventy-third
ord 23456
twenty-three thousand four hundred fifty-seventh
ord 8007006005004003
eight quadrillion seven trillion six billion five million four thousand fourth

jq
Adapted from Wren
Also works with gojq and fq, the Go implementations
One point of interest in the following is that the program checks not only that its integer input is within the scope of the program, but also that it is within the capability of the C or Go platform. In particular, `check_ok` checks for the platform's precision of integer arithmetic.
For further remarks on this point, see the comments that are included in the test data.

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.

Raku
(formerly Perl 6)
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 task code. Much simpler to just use the Lingua::EN::Numbers module from the Raku ecosystem though. It will easily handles ordinal number conversions.
We need to be slightly careful of terminology. In Raku, 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 Raku 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.
Raku 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.

This reuses the say

Note that it is not safe to use this script for numbers with an absolute magnitude >= 2^53 as integers cannot be expressed exactly by Wren's Num type beyond that limit.
