math problem

[Chiwa]

Hey,

Expression:
Math.floor(x * 100) / 100

x= 4.1 gives 4.09, why in gods name?
While other values for x don't give a problem.

Thx in advance

Because browsers are not calculators (here = sign is "can be").

4.1 = 4.100000000000
= 4.099999999999
= 4.100000000001

So:
4.1*100 = 410.0000000000
= 409.9999999999

So:
Math.floor(x * 100) = 410
= 409

And so your answer can be 409.
How more devisions, multiplications and roundings the bigger the margin to
the exact calculation may grow.

No, you just did not find them ;-)

Just so you know, this is not just a limitation of Javascript. Many
other languages (C/C++ for instance) have this as an issue. That is
because Real numbers (floating point numbers) are _ALWAYS_
approximations. When you do a measurement of your finger (for
instance), and you measure exactly 1.25 inches... is that really
correct? Or could it be 1.25000002343589 inches instead? Or
1.2500000034322349872342229? (You get the idea)

For this reason (and others dealing with the complexity of floating
point numbers), when a float (indescrete) is represented by binary data
(descrete), you will have some goofiness... it is guaranteed.

Because of this, most languages have methods for you to set the
precision (the number of significant figures), where rounding will occur
to the precision value you wish for.

If you desire an exact floating point value, such as in something like
money calculations, simply set your precisions.

You can also work in values multiplied by (10*order)... For instance,
$10.47 can be worked with as integers... immagine 1,047 pennies :) You
can convert it back by dividing or modding by (10*order) in integer form.

I have had to use that method once when developing assembly code on an
8-bit processor. There was no float support, so I needed to work in
values multiplied by (10*order), and then do some simple calculations to
provide useful user information.

Blah.... I wrote too much. Oh well, I hope it helps :)

After working on my order form code it appears that I noticed and
solved this same problem long ago.

What I do is to add 0.000001 to the value x before putting it through
this same function, when this makes sure that the value is not below
the true value before you run the calculation.

Since this fraction is so small, then it would be rounded off
anywhere, where you only have to watch out that your x value does not
use this many decimal places.

That of course is not a problem for money values, like what I use it
for, with only two (or three with VAT) decimal places.

There you go, perfect rounding results every time.

You have got to be careful with a solution like this, since it is just a
hack, and can be confusing to maintainers in the future. You should
really use precision mechanisms built into the language to solve the
problem more elegantly.

JavaScript Numbers are 64-bit floating point as specified in IEEE 754.
It is the same representation that Java calls Double.

The scheme is intended to preserve as much precision as possible, but it
has some significant weakness. For example, it is not able to exactly
represent common fractions such as 1/10 or 1/100. It can at best
approximate them. As you can see, with a single operation you begin
accumulating noticeable error. Also, be aware that the associative law
and distributive law do not apply.

I think floating point is the wrong representation for numbers in most
applications. However, it is extremely popular, and popularity is much
more important these days than suitability or reliability. I recommend
that in applications that require exactness (for example, when working
with money) scale your values by a suitable factor (such as 100) so that
all of your arithmetic will be on whole numbers, which are exact.

I think this:
adding 0.0000001 and then use setPlaces(2);
will only be the solution when one want to have the code work in Netscape 4.
Exept that browser, a value of 4.1 will become 4.10 when directly used
setPlaces(2) (according to precious referred page).

Sorry correction:
The input is x.
Make it a string.
Then get the lastIndexOf(".") that string.

If it's -1 -> add ".000"
If it's string length-2 -> add "00"
If it's string length-1 -> add "000"
If it's string length -> add "000"

Now parceFloat and setPlaces(2).

Except that the value is in Sterling when that calculation is done,
where it is only converted to Euros following this.

Even had I used a different method, then the Sterling value before
Euro conversion would still be exactly the same. As I said the value
is too small to ever effect the total.

Advice: remove the translation link for Dutch.
The page becomes none readable; it uses old words and a word by word
translation to the wrong words.

Welcome must be "Welkom"
Not welkomsgroet that can never be the first wordt in a line, so why it's
even chosen.. it's a very rare used word.

And that's only the first word. For all Dutch people the original page will
be way better and faster readable.

I think this holds for most Systran translations.
Even the tekst on their own page uses incorrect chosen words and bad
grammar.

Well the problem is that I know how terrible machine translations are,
but in most cases it is better than nothing. My pages have way too
much text and change too often to consider real translations.

So if you don't like the translation, then stick to the original
English version.

Yes... Still, for those people who do not know English, then they
really are better than nothing, even if they manage only a crude
translation.

I have been doubtful of the Systran translations for a long time,
where maybe I should consider removing them.

Most Dutch do also speak/understand German and have a 3 to 6 years education
in Frensh.
It's our custom to try to speak the language of the countries we visit for

I dislike dubbing, some commercials are in dub, then I always zap to an

Well, Wouter, not everyone. For Internet purposes though your statement
below is completely valid.

That is officially. Dutch and Frisian (the latter locally) can be used
by the government for communication.
In Holland, either Turkish or Maroc (er, what's that ending?) will be
the second language in frequency. I guess.
Still, it does not mention English for Sweden

Agree; given only the 'dutch' version of the page, I think I still would
have failed to understand what it is about--let alone get the details.
In fact, to understand a bit of that version requires *quite a lot* more
English knowledge than the English original!
There are no Dutch people who don't know English.
Know? My son doesn't know English. But then again, he's only 4. ~ ~ ~

Yeah, and keep synchronized sound tracks. Yulck.

(remember that hacked software is mostly in English, so it's a must for

You call that a joke? I call it a chore! Software translation happens,
but most often it helps to know the original terms to understand what
the comments are about. Let alone the fact that English often takes up
less space on screen, so texts in Dutch get trunca someti.

I happen to have quite some customers where I'd better not use any
english word in my software (I happen to be a developer ;-) ) because
they don't get it then!
As a matter of fact, I think I can come up with quite a few people for
whom English is not a real option.

In the case of defending arguments (or on emotional subjects) I prefer
to use a neutral language. English suits me perfectly except when the
other party is a native speaker. You probably wouldn't want to take on
me in Dutch, would you?

One fundamental error is that Math.floor is being used where Math.round

Another is that there is almost no intrinsic need to round numbers to a
multiple of 0.01; the need is to convert a Number to a String with two
decimal places.

I would.

Then there is the other 77 pages...

My best idea for having a multiple language site would be to remove as
much information as possible, including minimum item information with
no real description except the photo, then to have this very compacted
site translated into many languages as possible.

The only real problem is when adding new items, but you can just learn
the phrase "No Information Available" in all the languages.

Having my current site translated, even for free, is a crazy idea,
when other languages cannot be maintained for any real time, despite
such promises.

Yes I could well get rid of the Systran options, but then there would
go most of the flags as well.

Maybe one day I may actually do that multi-language shopping site,
when a photo based selection gallery in lots of languages is not too
hard. The only issue is that customers like shopping in their own
country, which is a difficult one to solve.

In fact one of my rival suppliers already does a system like that,
where he is a little too successful.

My best idea for having a multiple language site would be to remove as
much information as possible, including minimum item information with
no real description except the photo, then to have this very compacted
site translated into many languages as possible.

The only real problem is when adding new items, but you can just learn
the phrase "No Information Available" in all the languages.

LOL
Having my current site translated, even for free, is a crazy idea,
when other languages cannot be maintained for any real time, despite
such promises.

True. Yet it happens that especially Dutch (or, to be honest, germanic
languages in general) needs manual assistance. Keep Systran. Please do.

Just checked the German version--it can be read.

But for the Dutch version, how much time/patience have you got? The
offer stands. Translating into Dutch is not as much a problem for me as
translating into English ;-)

You know what? Relieve some of the strain on the translation machines by
using shorter sentences. (Sorry, that is a bad example).

An example:

"To begin with then if this is your first visit then odds are that you
came here because someone you know recommended you to visit"
this is bound to cause trouble.

"Is this your first visit? Possibly your friend has recommended this
site to you"
has a little more universal structure. Maybe it is not your style of
writing; but you won't develop a style of writing in 8000 languages,
would you?

One fundamental error is that Math.floor is being used where Math.round

The calculation is being done for VAT. Customs & Excise rules state

Since I believe in giving that 1p to my customers instead of tax man,
then that is why the Math.floor function is used.
Another is that there is almost no intrinsic need to round numbers to a

It is quite interesting when you examine this problem at the bit
level, but why the used a rubbish fuzzy number system in the first
place is a good question.

It is a case that people with multiple language skills can better
understand the language construct or grammar. Others of us are still
working on the one we have.

Since that text of mine seems a bit doggy these days, then something
like "Should this be your first visit to this site, then the odds are
that someone told you to visit" would be better.

Yes I could go and rewrite my entire site and improve the text, but I
work on a gradual improvement system. So when I am doing some large
work on a page, then I can review all the text on that page.

Over the last three and a half years that Welcome page first got
wrote, then about two years ago it got improved. I have been feeling
for a long time that it needs another improvement.

Should you really desire to translate my site into Dutch, then be my
guest. As the worst case situation is that it just gets neglected if
you get interested in other things.

Just don't try translating the News page, when I tend to type a lot,
where that News goes all the way back to 2000.

The best way to do this is to just translate the paragraphs into a
text file, where I can then paste these into the right sections on my
HTML pages.

Should you really want to translate all suitable pages, then there are
about 38 pages excluding all the News ones. There are a few pages that
are not easy to find, where I would have to point those out.

The first job would be to translate the welcome page and the menu
text.

And since it is best to e-mail me to discuss this further, then you
can do so at yourads at cardman.co.uk.

Well, good luck, when the last attempt to translate my former site was
back in 1998 to Svenska. For nostelga purproses, then I have put the
Swedish version of my old site here...
http://www.cardman.co.uk/esg/Svenska/

You can see that 9 pages were translated before he gave up, where I
will keep that up for a few days before removing it again.

Maybe, you can test serverside if one visits for the first time.
You can check with script or serverside if one comes via google..

So you don't need to guess.. that bad.

Then it shows more professional I think.

And maybe just start to tell people what's the site about.. instead of
guessing where they come from or how that they did find you.

Maybe you want items to be clickable and then be added to a basket.
PHP-Nuke is a free php/MySQL script to built a website that also has
shopping script and can handle multiple languages.

I believe the difference is that Ireland (Eire) has accepted the fact
that English has assimilated the population, but they have not
scrubbed off the former national language yet.

The same thing happens in Wales to a lesser degree, when more people
their speak English than Welsh. One reason could be the neighbouring
English crossing the mountains into dragon country.

It would be nice had it listed what a large percentage of the
population can speak, instead of what the politicians desire the
population to only speak.

My atlas notes gaelic as regional (western parts) and diminishing in
use. No notes about first or second language.

JRS: In article <gf********************************@4ax.com>, seen in
news:comp.lang.javascript, Cardman <do****@spam-me.com> posted at Tue, 3
Feb 2004 23:04:36 :-

(VAT stuff) : I was not addressing your situation, but the defects of
your answer to Chiwa's original question, and the probable context of
that question. When responding to an article in News, it is wise to
examine the position of that article in its thread, and at least to
review its immediate predecessors.

Another is that there is almost no intrinsic need to round numbers to a
multiple of 0.01; the need is to convert a Number to a String with two
decimal places.

The need is to display the correct answer, where that is being done
string or no string.

Numbers cannot be displayed; only strings can. On output of a
javascript number, there is an automatic conversion to string.

Consider document.write(3.00) - the result will be 3, not
3.00, and that is correct by language definition.

The usual reason for wanting to truncate a Number to a multiple of 0.01
is that a currency calculation with input sums to two places gives a
result with rounding errors which displays something like 3.00000000001;
"numeric truncation" and "numeric rounding" both give a Number of 3,
displaying as 3. Those who use numeric truncation eventually discover
that they need to change to numeric rounding, in order not to lose one
unit up to half the time.

But they then see that sums of money such as three pounds, three pounds
five pence, and three pounds ten pence display as 3 3.05 3.1, whereas
convention demands 3.00, 3.05, 3.10. To get those in javascript the
Number must be converted to a String with two decimal places before
output.

The conversion needs a function.

There is no need to round the number before the function; it is better
to do it within.


I see a possible problem with your VAT approach. VAT here is 17.5%.

In any language using IEEE Doubles,
1.175 - 1.0 - 0.125 = 0.050000000000000044
0.175 - 0.125 = 0.04999999999999999
Here 1.0 and 0.125 are numbers that an IEEE Double can represent
exactly. So 1.175 is stored as slightly more, but 0.175 as slightly
less.

Thus for ten items costing GBP 1.00 exc. VAT, with truncation, the
customer may be called on to pay GBP 11.75, and the VATman may be
offered GBP 1.74. Accounts may show a discrepancy of one penny.
Amusing thought : % means /per centum/. Literally, a VAT rate of 17.5%
means not that the tax is the net times 0.175, but that for every 100
pence in the net the tax is 17.5 pence --- and 17.5 can of course be
represented exactly. If the calculation had been done literally,
calculating the pennies of VAT from the hundreds-of-pence net, the
results would have been exact.

So it has nothing to do with national languages, English is not a
national language of Eire.
I believe the difference is that Ireland (Eire) has accepted the fact
that English has assimilated the population,
It'd had assimilated the population even before 1911 I believe.
It would be nice had it listed what a large percentage of the

What? The Irish don't even get the EU to produce documents in it
national language (uniquely AIUI) because so few people can.
