ActionScript 3 :: Flash - Math.floor Acting Like Math.round?
Mar 7, 2011Here 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?

Jan 16, 2004So here is a piece of code that I have seen used a lot but don't really quite understand:
myVar = Math.min(Math.max(myVar, this.min), this.max);
or some variation thereof. I understand that the function first finds the maximum value of two values then turns around and uses that to find the minimum between two values.why this is done? And how do you know when to use it?

View 6 RepliesActionScript 3.0 :: Math Differences On PC And Mac
Jun 27, 2011I have created a flash 3d racing game which relies heavily on AS3's Math functions (sin, cos, tan, asin, acos, atan). It also makes heavy use of Matrix3D and Vector3D functions. The game works great on a PC, but the cars flip around and display innacurate positions on Mac computers. I know this is an issue due to the note on the Math docs page: [URL]
which states: "Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU (or operating system if the CPU doesn't support floating point calculations) when performing the calculations for the listed functions, and results have shown slight variations depending upon the CPU or operating system in use."
how do I get this game to work on a Mac? I've tried using lookup tables and inline FastMath style approximations. But lookup tables still create the same problem, and the inline approximations I have found are not accurate enough for my game. I've also tried rounding values with floating point errors, but that has not seemed to help (in my implementation) either. I think the specific problem is with the use of Math.atan. I have not found an accurate approximation for this.. but I maybe that is not even necessary.

ActionScript 2.0 :: Math, Ratios Between +/-'s?
Apr 24, 2003here's where all you math genius' get to help me out. I know that this principal is not difficult and was taught sometime during my highschool years.I need a math formula which reduces the ratio of any x:y to the smallest quanity possible. Basicaly so that the smaller of the two numbers is 1 and the other number is whatever it would be, compared to 1... but, I need it to work for both posative and negative numbers.(I'm the ultimate Math newb.. bear with me)
so. I have x=20, y=20 is 1:1
-20, y=-10 is -2:-1
x=10, y=-5 is 2:-1
ect.
so what is the formula for that?
ActionScript 3.0 :: Math For Smooth Scrolling
Jun 12, 2009Envrironment: Flash CS3, AS3 I have a horizontal image scrolling project that I am working on, and it works but is not super smooth, I would like it to be smoother when it scrolls, and realize that this is a function of pixels scrolled over time and the FPS of the document.
Right now I am moving the items 1 pixel at a time on a timer with delay of 8 to get it to scroll at the speed I want. I am moving it at 1 pixel in order to catch exactly when an object should wraparound to the beginning of the scroller to show up again. So I don't know that I can really change the number of pixels moved to more than 1 and still have the images spaced perfectly, which makes me think I need to increase or decrease the FPS and or the timer delay to make it scroll smoother. Right now it is at 30FPS and as mentioned the timer delay is 8. Small changes to the delay is not a problem.
This is one aspect of flash i don't fully understand. I would really like to know how to figure this out so I can apply it to future projects as well without doing trial and error to make it smooth. Can it be function, like a way to figure out I need to move a 120pixel picture 60 pixels in 2 seconds, what should my FPS be and the picture size and movement size and number of seconds can be variables?
ActionScript 3.0 :: Math For Rotated Dragging?
Aug 17, 2010this math isn't working well. I'm using it for a rotated drag and drop (of a tone arm on a vinyl, a kind of abstract turntable simulation). Right now it just moves a bit in the middle of the vinyl (values between 21 and 36, is this degree or what unit is this?), but it should move between the two edges. The problem is that I don't know enough about trigonometry functions. Therefore I can't optimize the math for envisaged behaviour. Does anybody have an idea/tip how I can get a bit more control on the math and its effect? (maybe with more trace functions)

Flash :: The Math Class Does Not Appear To Exist?
Dec 11, 2011I think I broke my Flash. I'm using Flash CS5.5, and when I use AS3, any references to the Math class give me errors like this:1061: Call to a possibly undefined method sqrt through a reference with static type Class.1061: Call to a possibly undefined method pow through a reference with static type Class.1061: Call to a possibly undefined method pow through a reference with static type Class.The code in error is this:var dist:Number = Math.sqrt(Math.pow(initPos.x - pos.x, 2) + Math.pow(initPos.y - pos.y, 2));What the heck is going on here? Math is a top-level class, so I don't think I should be getting an error like this. Is it possible to somehow "break" the Math class? If so, how do I fix it?

View 1 RepliesActionScript 3.0 :: Math To Bias Values?
Feb 6, 2010I have an app (historical timeline) in which I am using one object (driver) to scroll another (driven) - like a scrollbox.There are limits on the movement of the driver, so I am using the % of the driver's movement to drive the % of the driven object's movement. It works fine on the ends of the driven, but I need to distribute the movement so that the driven object moves more at the end than at the beginning.Basically I need to multiply the % so that it moves from 0 - 1 non linearly.

Strangely, the object flies up after a short while, meaning it floats up and down, but more up than down, even if the script itself is pretty straightforward.
