ActionScript 2.0 :: Math - Find Out If Number Divisible By 6?
Aug 19, 2007
I have a for loop that arranges icons in rows, and I want 6 icons per row. The number of icons is variable. So I was thinking that if I can find out how to test if a number is a perfect multiple of 6 (or 7, I suppose), I could then add a line in the loop that changes the _y value of the thumb to a higher number and resets the _x value to 0, thereby creating a new line. how do you test to see if a number is round?

I need to be able to round a given number to an even number that is divisible by 10, 100, or 1000 depending on it's size.
For example:
4 would be 0 -- Round to nearest 10
6 would be 10 -- Round to nearest 10
54 would be 50 -- Round to nearest 10

I've been scanning the WWW for a formula to do this in as3, but have come up empty handed.

I know making a random number divisible by 10 means it isn't so random after all, but stick with me. Imagine a game grid of tiles that are 10x10 pixels. I want to place a 10x10 sprite randomly on the game grid. I've got everything working other than getting my random number function to return random numbers that are divisible by 10. If I give it a range of 10 and 50, I want it to only return 10, 20, 30, 40, 50. You know what I mean. Here's my function:

im trying to create an image gallery where i place my images randomly over the stage but i want to place the images in the next most empty spot over the stage, for example if all the images somehow have been placed at the right of the stage i want to use math to detect that and find the empty left position .
Im sure there is a math formula to do it , will somebody knows the name for it ? or a link ?
i found this but uses hitTest and thats not efficient and it doesnt finds the big empty spot: [URL]

So, right now when I want to find the distance between two points, I go: dist = Math.sqrt((this_x-that_x)*(this_x-that_x)+(this_y-that_y)*(this_y-that_y)) BLECH! I don't want to do that every time. So I want to make a nice little function that I can apply to an object. Problem is, I don't know how to do this. Is it possible to end up with something as easy as: Math.dist(thisclipname, thatclipname)? How do you guys set up functions that do bulky math and return nice clean numbers?

I have created a tween with actionscript that moves a movie clip of a cityscape along the x axis whenever the mouse is clicked.
This is my code
var skylineTween:Tween=new Tween(skyline_mc,"x", Regular.easeInOut, skyline_mc.x,Math.floor(Math.random() * (-1022 - -16) ) + -3,2,true);
Right now it generates a random number from between -1022 and -16 (positions along the x axis).
However, sometimes the skyline movie clip only moves a few pixels and looks boring.
I added 200 pixels to the movement (Math.random() * (-1022 - -16) +200 ) and it looks better. However, sometimes this slides the movie clip past -1022 or -16 and off the stage.
How can I set the value to +200 without passing -1022 or -16?

I'm trying to play a random gallary image by making it stops at different frame every few seconds, and the actions is completely random.
The problem is, since there are only 5 different images(5 frames) I'm displaying, there is a high probability that it stays at the same frame, how do I avoid that? Like avoid staying at the same page twice, if not run the function again.

Alright,I have the MC I wanted to move everytime "A" is pressed now. But I still have one more question. Right now I have a random number generated between 1 and 10. Every time that "A" is pressed my horse (for the game) moved across the x axis in an increment between 1 and 10 (the random number). BUT the problem I'm having is that when the "A" button is pressed it loads a random number and uses that number over and over when I press the "A" button.How do I get it to load a new random number everytime "A" in pressed?

I was wondering if there was a way to convert a string containing math symbols such as +,-,*,/ and numbers. I am building a calculator.I have a string variable that I keep appending the value of the button.In the end the string looks something like this 8+3+3-4*9.I was wondering if there was a way to solve the equation just using the information in the string. I tried setting a Number to the string and I would get NaN. The hard part about this is trying to count for the math oop i.e Multiplying before adding.

I recently bought a new machine and tried to put my Flash 8 software onto it. The serial number was fine, but it requested the serial number of the software I upgraded from, which I no longer have (MX, I think it was. I threw it out ages ago thinking I didn't need it ). I can't even remember what email address my macromedia/adobe account was under, it might even be under an email address for a domain I no longer have.
I do still have the software installed on my old PC. Is there anyway I can find out the serial number of the MX I upgraded from off of the Flash 8 on there? Or it is a lost cause?

Im looking to be able to find a number (any number) within a text string, what i ultimately want to do is crop the number out of the string to just be left with a number value, the only problem is the string could be any length and the number doesnt necessarily start at any point from the last characterI have items on the stage named 'image0', 'textfield2', 'button500' etc, as you can see the prefix before the number isnt a fixed length so I couldnt use substr and set an index, and since the number could be any number i couldnt set the index as a certain value before the end of the string. (ie it might return '500' or 'ld2' or 'ge0' in the examples given before)

Here is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?
