Cardinals and ordinals, 1 to 100

Question

Here's a simple one to stretch your compression muscles. Your code (a complete program) must output the spelled-out English representation of all the cardinal numbers from 1 to 100, and then all the ordinal numbers from 1 to 100. The numerals in each list should be delimited by commas and spaces and properly hyphenated. Each list should begin with a single capital letter and conclude with a period. The two lists should be separated by a newline.

For clarity's sake, you must produce this exact byte stream:

One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, thirty-one, thirty-two, thirty-three, thirty-four, thirty-five, thirty-six, thirty-seven, thirty-eight, thirty-nine, forty, forty-one, forty-two, forty-three, forty-four, forty-five, forty-six, forty-seven, forty-eight, forty-nine, fifty, fifty-one, fifty-two, fifty-three, fifty-four, fifty-five, fifty-six, fifty-seven, fifty-eight, fifty-nine, sixty, sixty-one, sixty-two, sixty-three, sixty-four, sixty-five, sixty-six, sixty-seven, sixty-eight, sixty-nine, seventy, seventy-one, seventy-two, seventy-three, seventy-four, seventy-five, seventy-six, seventy-seven, seventy-eight, seventy-nine, eighty, eighty-one, eighty-two, eighty-three, eighty-four, eighty-five, eighty-six, eighty-seven, eighty-eight, eighty-nine, ninety, ninety-one, ninety-two, ninety-three, ninety-four, ninety-five, ninety-six, ninety-seven, ninety-eight, ninety-nine, one hundred.
First, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, nineteenth, twentieth, twenty-first, twenty-second, twenty-third, twenty-fourth, twenty-fifth, twenty-sixth, twenty-seventh, twenty-eighth, twenty-ninth, thirtieth, thirty-first, thirty-second, thirty-third, thirty-fourth, thirty-fifth, thirty-sixth, thirty-seventh, thirty-eighth, thirty-ninth, fortieth, forty-first, forty-second, forty-third, forty-fourth, forty-fifth, forty-sixth, forty-seventh, forty-eighth, forty-ninth, fiftieth, fifty-first, fifty-second, fifty-third, fifty-fourth, fifty-fifth, fifty-sixth, fifty-seventh, fifty-eighth, fifty-ninth, sixtieth, sixty-first, sixty-second, sixty-third, sixty-fourth, sixty-fifth, sixty-sixth, sixty-seventh, sixty-eighth, sixty-ninth, seventieth, seventy-first, seventy-second, seventy-third, seventy-fourth, seventy-fifth, seventy-sixth, seventy-seventh, seventy-eighth, seventy-ninth, eightieth, eighty-first, eighty-second, eighty-third, eighty-fourth, eighty-fifth, eighty-sixth, eighty-seventh, eighty-eighth, eighty-ninth, ninetieth, ninety-first, ninety-second, ninety-third, ninety-fourth, ninety-fifth, ninety-sixth, ninety-seventh, ninety-eighth, ninety-ninth, one hundredth.

Explanations

See Formatted Output to Character Streams.

• (format t "<control string>" <arguments>) formats the control string according to the (variadic) arguments and prints to standard output (because t)

• (loop ...) builds the list of integers from 1 to 100

• ~@( ... ~) capitalizes the string returned by the inner control string

• ~{ ... ~} iterates over the current argument and applies the inner formatting to each element

• Inside the iteration, everything that follows ~^ is not printed on the last iteration: this is used to add the comma-space separator between elements.

• ~R outputs current argument as a cardinal

• ~:R outputs current argument as an ordinal

• ~% outputs a new line

• ~:* reset the current argument to be processed as the previous one, which is used here to reuse the list of integers a second time.

Small cheat here for the cardinals (I'm using the NumberFormatter class that comes default with PHP):

echo'One, ';$x=new NumberFormatter(0,5);for($i=1;$i++<100;)echo$x->format($i).($i>99?
'.':', ');echo"

$j++<99;$q=floor($j/10),$w=$z[$q-2])echo$j<21?$y[$j-1]:($j%10?$x->format($q*10).'-'.

That includes the newline character.

It's part of the NumberFormatter class, just like razvan's answer. Except I spell out both the cardinals and ordinals according to the ICU.

Explanation

This may look like a bunch of garbled characters but it's actually pretty simple.

We start by generating the cardinals. This array is compressed using the btoa function.

['one', ..., 'eighteen', 'nineteen', 'twenty', 'thirty', ...,'ninety']

To loop through a "range" we use the following:

Now we generate an Array of length 89 using. The ... is what uncompresses the array

Array(89).fill(...)

Then map through it, i is the index:

.map((l,i)=>

Now for the condition, i < 1 or if it is the first item, we will use a capitalized version of one / first

i<1?b

Otherwise... if it is less than 20, we output eleven...nineteen

i<20?a[i]:

Otherwise... using (i-i%10)/10 we get the last digit of the number. We add 18 to it to compensate for 1..19. We add a - and then add the last digit, or i%10

Finally, we add 'one hundred' to the very end because we don't.

We repeat this for both types of numbers and separate with a newline

// Find the kth null separated string in array b
auto p(int k) {
    for (s = b; k--;)
        while (*s++)

    return s;
}

int main() {
    // Decode the compressed 'primitives' we use to build up the output.
    for (; k = *s++;)
        if (k > 98)
            *t++ = k < '|' ? k : " "[k < '~'];

The compressed string is decoded from a into b:

|one|two|three|four|five|six|seven|eight|nine|ten|eleven|twelve|thirteen|fourteen|fifteen|
sixteen|seventeen|eighteen|nineteen||first|second|third|fourth|fifth|sixth|seventh|eighth|

eighteenth|nineteenth|||twenty|thirty|forty|fifty|sixty|seventy|eighty|ninety|one~
hundred|||twentieth|thirtieth|fourtieth|fiftieth|sixtieth|seventieth|eightieth|
ninetieth|one~hundredth;

Without the newlines. During decompression the |s are replaced with '\0' and the ~s are replaced with ' ' (quirk of the way the characters are encoded into printable ASCII). These 'primitive' strings are then looked up by index in the b array using the p function and used to assemble the output.

Compression is a simple LZ like scheme where characters are either encoded as literals or as a negative offset into the buffer and a run length (encoded into two characters) if a match of length >=3 is found. The string could be compressed further using non-printable characters but I like my code to be copy and paste safe :)

PHP - 842 bytes

Omitting regular PHP starting and ending tags, compression is 1 - 842/2445 = 65.6%

Basically getting the output of base64_encode(gzdeflate($input, 9)); and reversing the operations. Obviously, if I chose to output in pure 8-bit vs. base-64, it would be 25% smaller, but at the risk of running into escape or non-printable characters.
