# Too much time on my hands today...

I had a very quiet schedule at work today, so I thought I'd finish this
script. In theory, it should generate a random time between two moments
specified, round it off to a conventional interval if desired, and
convert it into text if desired. The text conversion routine is a
separate function which could be used more generally if desired.

It mostly seems to work ok. Anyone want to either borrow it or show me
some horribly obvious flaw that I've missed, or show me how my code is
woefully inefficient? I'm just inordinately pleased that I managed to
write all this without blatantly copying any pre-existing code.

Yeah, this is going to be used for one of my language learning games on
my website, strange as it may seem.

function anmar(i)
{
var a =
new Array(
null, "one", "two", "three", "four", "five", "six",
"seven", "eight", "nine", "ten", "eleven", "twelve",
"thirteen", "fourteen", "fifteen", "sixteen", "seventeen",
"eighteen", "nineteen", "twenty");

for (var j = 21; j < 90; j++)
a[j] = null;

a[30] = "thirty";
a[40] = "fourty";
a[50] = "fifty";
a[60] = "sixty";
a[70] = "seventy";
a[80] = "eighty";
a[90] = "ninety";

return (a ? a : null);
}

And that's not even splitted to atoms of language.

BTW: It is counterproductive to post scripts below the signature,
since a correctly separated signature is automagically cut on reply
by most news clients (I had to copypaste it in order to reply). And
it is counterproductive to post hundreds of lines of code instead of
posting the URL of a file containing that code. Bandwidth is precious.

I just polished up my numbers script. It now handles numbers as English
text up to 33 digits, in your choice of US/UK English. And it does that
with half the amount of code I had in the original. I made js think the
number string is text in order to avoid those floating point errors.

There is, unfortunately, a limit on how many digits that can be done for
the Japanese version. One of the Japanese equivalents to X-llions isn't
in the Unicode character set.

I am feeling pleased with myself today.

Great that you have a good time.

But what does it have to do with *coding* JavaScript?

That paragraph, nothing. The ones you snipped, plenty. Halving the code
length whiel tripling the range of numbers the script can handle is, by
my personal benchmark, non-trivial.

Do you want congratulations or stuff like that here, or do you want to
contribute to this newsgroup? If the latter, you could have at least posted
the code that pleased you so much or an URL where one can look at it. If
the former, why don't you keep that uninteresting piece of information for
yourselves?

This is a *news*group, not a hall of fame.

I would hope that anyone sufficiently interested would ask for the code,
in order to save bandwidth. In any case, I have, technically, posted an
url where the code can be seen. It is used on my website below, albeit
one click away and then you'd need to check the source to find the exact
location. But people are free to ask me for it.
