ActionScript 3.0 :: Finding The Digit Sum Of Large Numbers?
Dec 7, 2011
How do I find the digit sum of a floating point number?* (Eg Math.pow(10,100)). The correct answer would be 1. I have tried writing two functions, function A does not work for floating point numbers due to it converting numbers to strings, function B does not work for Math.pow(10,100) and other floating point numbers).
Specially: (1 with X zeros) % 10 = not 0, according to flash.
*Alternatively, what method can I use that gives me the last digit of a floating point number, and works for 1 with some number of zeros?
My functions:
private function getDSum(input:Number):Number {
var res:Number = 0;
for(var i = 0; i < input.toString().length+1; i++){
Is there any way to force a two digit number with actionscript? Say, for instance, that I have a for loop that traces the numbers 1 through 9. In the output panel, I only get one digit numbers: 1, 2, 3,...9. Is there any way to make the trace output be 01, 02, 03,...09?
Obviously I could use an if statement to manually add zeros to all numbers that are less than 10, but is there a cleaner way to do it?
Problem is, when I try the comparason if the one of the numbers has a higher digit value, it ignores the statement entirely. Eg If 16 > 8 it skips it. So I tried adding '16' and '08' into the array and that worked perfectly with the statement.
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?
am developing an application which requires a consecutive searching side to it. Basically, I need a function or a class which takes an array as the parameter, and return the possible 3 consecutive numbers in a 2 dimensional array.For example, if I have this code:
ActionScript Code: //Global array var glob:Array=[0,1,2,3,4,5,6,7,8,9];
I am working on a maths game which involves generating some large numbers in AS3. When I pass these numbers into a textbox they appear as e.g. 300000, I would like them to appear as 300,000.Is it possible to format a text box to do this?
I'm trying to get the 255 smallest numbers from an array made up of all the alpha values in a given BitmapData, and storing these numbers in the Alpha array for paletteMap().We all know how to get the smallest/highest number from an array, or to delete repeating numbers or even to average numbers inside an array. I've been tweaking for 2 days with these possibilities but unfortunately I can't find anything satisfactory.
I am using a Dictionary where the keys are Number objects, but I run into unexpected problems if the keys are large integers.
Here is some example code that inserts two key-value pairs in a Dictionary, one with a small key and one with a large one:
var dictionary:Dictionary = new Dictionary(); var smallNumberKey:Number = 1; dictionary[smallNumberKey] = "some value";
[Code].....
None of the keys seems to be stored as a Number. Why is that? The first one is stored as an int, which can be converted to a Number. The second one however seems to be stored as a String, which makes no sense to me. What is going on here?
What to use when 32 bit ints or even 53 bit Numbers arent large enough by far? Im thinking of just using a 256 bit array but theres prolly a better way.
I have plans to make an RPG that is similar to those on the SNES as far as movement goes- you walk one tile in a direction at a time and if the tile that you are trying to move to has been marked as one that can't be walked on, it stops the character from going there. That means that conventional collision wouldn't quite cut it.
So I decided that I would make it to where every tile will have a specific value (one to say that there is no collision, another to say there is, etc.), and every object will have an X and Y value that changes in relation to the character (because there is scrolling in this project).
The thing is, there will be a lot of objects, and there will be a lot of tiles; this will quickly become an unimaginably huge project if I just go ahead and throw objects in.
So, what would be the most efficient way of storing these values? I was thinking of storing it in an XML file or a class, but I haven't really done it before, so I want to get a second opinion before I try and do so.
I was wondering if anyone here had any advice on rendering large numbers of identicalanimated instances. The first step we undertook was to separate out the parts of the instance which are static and render flag them cache as bitmap. However I was wondering if there was a way of rendering the same object multiple times without the player having to recalculate the animations separately for each etc?
I want to have a text with digit size of about 300, but at a certain digit size, when i increase the digit size more, it will not increase in the swf file (even though it will increase as i intended in the .fla file).Is there a max digit size, and if so, can i increase it, and if not, why is this happening?the textfield is a dynamic textfield made in the .fla file (so not in as3).
I have this problem getting the numbers from a xml to flash because I only getting two-digit and hay need to get like 8 digit numbers and I dont know what happen.
Here is a example of the code:
var mybook:Number = 0; var mymagazine:Number = 0; var mycolor:Color = new Color(mccolor);
Is it possible to access a certain digit in a string? For example, if i currently had a value '321' then if i clicked on a button for example it changed the 2nd digit in the string to say 5...making it '352'.
This is probably really easy to do but im not sure how to do it!
how to specifically target the last digit all the way to the right of a number?For example, I have the numbers 113, 222, 1114, 318, 219 and I want to check if the last digit in the numbers equal 3, 4, 8, or 9.
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.
create 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.
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.
Everything seems to be a string right now & that kinda ruins the whole xml as an internal data structure thing, I don't need a big tree of string I need typed data :-/ Are there any changes I can make to either my XML files or my AS3 code that will force it to cast ints as ints and Numbers as Numbers? 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...
