I don't understand why my number generates more than two decimal places after toFixed is applied. Am I misunderstanding the purpose of toFixed()?
Here is the code (one case in a switch):
Code:
case jewelry:
m_premIncrease = m_premData[m_selectedIndex][0][0] * m_premData[m_selectedIndex][3][0];
trace("Jewelry premium increase is " + m_premIncrease);
m_premIncrease.toFixed(2);

I'm making an application in actionscript that deals a lot with numbers. One of the problems, which has been driving me nuts for a while now, is "almost integers". Essentially, if I do something like the square root of 3, then square it, it gives me 2.99999999999999 (this is just the easiest example to test with). I've tried forcing it to round to a certain decimal place ([URL]), using toFixed, toPrecision, and math.round.
I've been spending all afternoon on this, and have found that actionscript uses 15 point/precision floating numbers. So with the squareroot/square of 3 above, if I specify it to go to 14 decimal places/significant figures, it gives me 3.0000000000001 (essentially ending with a 1), and if I specify it to 15 digits, it gives me (2.9999999999999).
I'm pretty sure that Actionscript is trolling me, because if the number was 2.9999999999999 (15 digits) and I rounded it to 15 digits... it'd make sense to keep it the same because there is no number after the last 9. However, if I round it to 14 digits, shouldn't the 14th 9 (15th digit) be chopped off, and the 13th 9 (now the last digit) rounded up, and making it carry over until it just becomes 3? Where did the 1 come from when rounding to 14 digits? If there was a 9 before that, shouldn't it have made it round to 3 when rounding to 15 digits?
i have a bunch of movieclips inside a container movieclip.they all have really crazy coordinates, like x: 1590.24 and y: 696.66443i was wondering - is there an easy way to "quantize" them to round their coordinates to the closest integer?

var awd:Number = 1;
var dwa:Number = 0.5;
var aaa:Number = (awd * dwa).toFixed (1);
Implicit coercion of type String to type Number. I'm using toFixed cause 0.14 * 50 was giving me 7.000000001 instead of 7.
sometimes when within an onEnterFrame, when I add var1+=var2 flash doesn't do it's Math the right way. It sort of says 2.15+2.45=4.55 I'm using trace() to check on the values and that is exactly what it does.
View 14 RepliesI'm doing some calculation with numbers and would like to only print an integer (the number without the decimals).I thought that the toFixed() method of the Number class would do the trick, and it does most of the time. But quite frequently strange values are returned. Here are 2 examples:
Number(0.002).toFixed(0) returns
"0." while
Number(1.002).toFixed(0) returns
"1" (without the period)
Once in a while, Number(0.002).toFixed(0) returns "1"
Needless to say that's not the expected behaviour. Am I not using this method correctly?
*edit: I know I just have to do int(0.002) to get 0 but I'd like to understand that strange behaviour.
I ran in to a problem I could not solve for a very long time While I was using Actionscript 3 in order to change the text of a classic text object in my .fla flash file, I did not see any change in my text field, and noticed that it doesn't display any numbers and some other characters (just some specific letters DID work).
View 1 RepliesI have firefox 3.6.15 with flash debug version 10.3. whenever an error occurs a popups comes up with the error and a stack trace but it does not line numbers of each leaf in the stack trace which makes it more difficult to debug. how to configure it to actually show line numbers ?
I think it may relate to how I compile my flash application. (i think!) i use eclipse FDT 4.2 to compile and i added the following compiler flags: -debug=true -compiler.verbose-stacktraces i think these parameters should be enough but I may be wrong.
how to do this and not found much, so here goes:
I want to generate a variable number of random numbers less than 16 with no duplicate numbers
Ive posted the fla, and what i'm doing is generating a random number and putting it into an array then using a for loop to cycle through the array for each new random number to check if its already there. if it is, then i want to regenerate that number.
if you test the fla you'll see that all i get in my array is some lovely zero's and i sort of know why this is, but don't know how to stop it.
I am trying to convert a string having numbers to an integer.
//15 9's are there
var str:String="999999999999999"
var res:Number = new Number(str);
But it is not able to convert correctly as the the var res now has the value 100000000000000000. I know that the number has 52 bits of memory, then why is it not able to do the conversion?

View 8 Repliescreate a function that picks out X amount of numbers from a set of numbers? So if X=3, then i need this function to pick out 3 different numbers from say a set of numbers (1, 2, 3, 4, 5, 6, 7, 8) and then stored it into X number of variables.
In saying that, X will only =2, and =5. So in the first instance, i'll need 2 random numbers from the set above that are not the same numbers, and second instance 5 random numbers from the set above (also no repeats of numbers). Then i need to be able to store those 2 or 5 different random numbers from the set into variables to call them with other functions.
what is the syntax to pick how can i pick 6 random numbers from 49 numbers

ActionScript Code:

trace(randomRange(3,-31));
But I need a code which will return some times '3' and some times '-31'. Not the number between them.
I have been using Actionscript 3.0 in Adobe Flash Builder for a few weeks,and I really like it! Bare with me because I'm not really good at it, yet. Anyway, I was wondering how would I go by adding up odd numbers from an array of numbers? I know how to make all of the numbers add up, but adding only the odd numbers I'm not so sure how to do it.

Or maybe some kind of type schema I can impose? Not really worked with XML til recently so chances are I'm just ignorant of the canonical way to deal with this...

It works but the results are sometimes many decimal places long. Any way I can make my results round to two decimal places (accurately). So 5.6994 becomes 5.70 etc.
