Since the task deals with a natural language, a program's output should follow the normal language usage. How do you pronounce 1,001? "one thousand <i>and</i> one", not "one thousand, one". Currently Java, Ruby, Basic and Python solutions, probably among others, should be considered inadequate. --[[User:Ledrug|Ledrug]] 21:51, 22 June 2011 (UTC)

: That's probably a matter for local dialect variance. I pronounce it "one thousand, one", myself. Has a nice rhythmic pattern to it when counting aloud. "One ''thou''sand ''one''. One ''thou''sand ''two''. One ''thou''sand ''three''." etc. (I've been very, very bored in the past...) --[[User:Short Circuit|Michael Mol]] 13:12, 23 June 2011 (UTC)

== PARI/GP Code Doesn't Work ==

The code doesn't seem to work for numbers larger than three digits.

Using PARI/GP via the web on this page: [https://pari.math.u-bordeaux.fr/gp.html https://pari.math.u-bordeaux.fr/gp.html]

<lang parigp>Eng(n:int)={

my(tmp,s="");

if (n >= 1000000,

tmp = n\1000000;

s = Str(Eng(tmp), " million");

n -= tmp * 1000000;

if (!n, return(s));

s = Str(s, " ")

);

if (n >= 1000,

tmp = n\1000;

s = Str(Eng(tmp), " thousand");

n -= tmp * 1000;

if (!n, return(s));

s = Str(s, " ")

);

if (n >= 100,

tmp = n\100;

s = Str(Edigit(tmp), " hundred");

n -= tmp * 100;

if (!n, return(s));

s = Str(s, " ")

);

if (n < 20,

return (Str(s, ["one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "ninteen"][n]))

);

tmp = n\10;

s = Str(s, [0, "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety"][tmp]);

n -= tmp * 10;

if (n, Str(s, "-", Edigit(n)), s)

};

Edigit(n)={

["one", "two", "three", "four", "five", "six", "seven", "eight", "nine"][n]

};

test_nums = [1, 23, 456, 7890, 12345, 678901, 2345678];

for (x = 1, #test_nums, print(test_nums[x] " = " Eng(test_nums[x])));</lang>

This is the output:

<lang parigp>1 = one

23 = twenty-three

456 = four hundred fifty-six

7890 = eight hundred ninety

12345 = three hundred forty-five

678901 = nine hundred one

2345678 = six hundred seventy-eight</lang>
