Hi
i have a property on a COM which returns int64:
var Milliseconds=Form1.Player.AbsolutePosition;
however for somereason the typeof(Milliseconds) isn't number but unknown....
I can't make any use of this.
Does any one knows how can I transfer it to number?

There is no "unknown" type and, consequently, the typeof _operator_ (no
parantheses required) does not return an "unknown" string, only
"number", "string", "boolean", "object" and "function". Please specify.
I can't make any use of this.
With that little information I can't either and I doubt anyone else can.
Does any one knows how can I transfer it to number?
Provided that the property is a 64 bit integer value it should be
converted into a IEEE-754 double-precision floating-point number
as this is the only number format J(ava)Script supports.

<quote cite="ECMA 262 3rd edition">
11.4.3 The typeof Operator
The production UnaryExpression : typeof UnaryExpression is
evaluated as follows:
1. Evaluate UnaryExpression.
2. If Type(Result(1)) is not Reference, go to step 4.
3. If GetBase(Result(1)) is null, return "undefined".
4. Call GetValue(Result(1)).
5. Return a string determined by Type(Result(4)) according to
the following table:
Type | Result
-------------------------------------------------
Undefined | "undefined"
-------------------------------------------------
Null | "object"
-------------------------------------------------
Boolean | "boolean"
-------------------------------------------------
Number | "number"
-------------------------------------------------
String | "string"
-------------------------------------------------
Object (native and |
doesn't implement |
[[Call]]) | "object"
-------------------------------------------------
Object (native and |
implements [[Call]]) | "function"
-------------------------------------------------
Object (host) | Implementation-dependent
</quote>
That final "Implementation-dependent" means that an alien primitive
wrapped in a host object has every right to return "unknown" if it feels
like it (and on IE some of them do).

Hello All
you are all missing the point,
i don't care what typeof returns.... ;)
Here is the definition of AbsolutePosition in the idl:
[propget, id(12), helpstring("property AbsolutePosition")] HRESULT
AbsolutePosition([out, retval] __int64 * pVal);
All I want to is use this value in jscript.
Every time I want to access this value as a number (of example
division) jscript gives me an error
10x for the replies

typeof Milliseconds can't be "transferred" to a number, since there doesn't
appear to be any "AbsolutePosition" property for the "Player" object on "Form1".
You can _try_ something like:
var obj = Form1.Player;
for (var prop in obj) {
document.write(
prop + ' = ' + obj[prop] +
' (' + typeof obj[prop] + ')' +
'<br>'
);
}
to see if it lists an "absolutePosition" or "AbsolutePosition" property.

I think in fact *you* do. Since ECMAScript and implementations use
IEEE-754 doubles only, there is no exact representation of a 64 bit
integer value in these languages. Proof: The largest value a signed
64 bit integer can hold is (2^63)-1 (1 MSB + 63 bits) which is
9223372036854775807. However, JavaScript (v1.5 in Mozilla Firefox)
returns 9223372036854776000 for Math.pow(2, 63)-1 because of the 64
bits available for the floating-point number some bits are required
for the exponent (the stored value is 9.2233720368547760E18):

If you would have bothered to read about J(ava)Script numbers as I
recommended previously, you would have recognized that "typeof" is
not really your problem.

[propget, id(12), helpstring("property AbsolutePosition")] HRESULT AbsolutePosition([out, retval] __int64 * pVal); All I want to is use this value in jscript.
You can use only a rounded representation of it.

I assume you are speaking about a COM object used in Internet
Explorer. Your best chance of getting advice about
IE/JScript-specific programming like this (or just to finde people who
knows what you are talking about) is the newsgroup
<URL: news:microsoft.public.scripting.jscript >
Does any one knows how can I transfer it to number?
My, completely unfounded, guess would be to do either
Milliseconds.toDouble()
or
Number(Milliseconds)
Good luck

I read the term "truthsayer" in some of the "Dune" novels by Frank
Herbert, a great American science-fiction writer and, as I have recently
found out, I was simply mislead by my linguistic intuition. Of course
I meant a different thing; a person with prescience -- a *soothsayer*.
It sometimes happens that a translation that is inspired by intuition
is not the correct one (in German, "soothsayer" is "Wahrsager" --
"truth-sayer"). But it happens more often to me that my linguistic
intuition leads to an appropriate translation. So far for *my* use of
the English language.
And what about *yours*? There are far better ways than this to tell
people that they have made a mistake (and people /make/ mistakes, that
is how they learn to better themselves). Especially for off-topic
notes, there is private e-mail. Do you really think your *continuing
completely off-topic personal attacks* here will do (you, this
newsgroup, me) anything good? I wonder how and why an university
graduate like you continues to display such a behavior in public.
If I were in your place, I would be very much ashamed of it.

If you are afraid of personal criticism, you should not post to Usenet.
Sticking your head in the sand by kill-filing your critics is cowardly,
and leaves you exposed as an arse. A better approach would be to
refrain from deserving such criticism - in particular, to terminate your
dictatorial attitude to those whose postings, while compatible with
Usenet custom, are in breach of some irrelevant German document.

least some posters who have never, intentionally or otherwise, written
anything but the perfect truth. Those who are not British
There are other countries on this planet that have the English language as official and/or native language.
It is true that many call one of their official languages English. In
many of the Commonwealth countries, many inhabitants use English as good
as that used by the English. But in many countries where it is an
official language, it is sadly mistreated by the less well-educated
natives. That is why I wrote what I did; it expressed my meaning.
The above statement of yours is only another proof of your arrogant attitude.

Rather long-winded; typically Murrican. In my youth, I thought that he
was moderately entertaining. You, too, should grow out of that,
eventually. But it is never wise to presume that a term used by an SF
writer is a current term in the language.
and, as I have recently found out, I was simply mislead by my linguistic intuition. Of course I meant a different thing; a person with prescience -- a *soothsayer*.
That's right. You used a pretentious word in ignorance of its meaning.
It would not be good for others to mis-learn from you.
And what about *yours*? There are far better ways than this to tell people that they have made a mistake (and people /make/ mistakes, that is how they learn to better themselves). Especially for off-topic notes, there is private e-mail.
Irrelevant; I have no interest in educating you, a person of noxious
disposition; only in preventing those (a large majority) who have more
pleasant personalities than yours from being misinformed.
P.S. Also, 'borken' is not an English word. Use, as is proper,
'broken'.

Actually, even some of the "less well educated natives" (more often
referred to by the English as those "dumb colonials") know that
"borken" is 'net clique-speak. And, as it is apparently intended to
do, draws response from those suffering the rasp.
However, neither to my knowledge, is "Murrican" an English word. Nor
is (capitalized) "Merkin". Both seem to enjoy a certain amount of
boilerplate exposure in postings under your name. It seems then,
readers should be entitled to draw appropriate conclusions (beyond not
fully trusting this posting) based upon your signature, wouldn't you
say? ;)
