Flex :: Return Multiple Variables From Math-crunching AS3 Function?
Nov 9, 2011I'm new to Actionscript programming. I'm trying to figure out what is the best way to return multiple variables, each having a different data type, from a function. For example, if a function needs to return variable aa ( a string) and variable bb (a number).
The function I'm using just crunches a lot of math, and doesn't relate to an object in a GUI. One method I got from a Google search used an Object, but as (I think) this requires me to create a class, I wondered if there was a simpler way. Since an array can hold elements of different data types, perhaps this is a simpler approach (?). [code]...

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?

ActionScript :: Flex - An Object Returned From A Function Call Changed The Next Time The Same Function Is Called?
Jan 10, 2012I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package
{
public class PER
{
[Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?
Flex :: Get Function Name From Function Object?
Aug 4, 2009Given a Function object, can you get its name as a String? See example:

This example is sort of arbitrary, but it would be very useful to get function names for debugging, particularly when passing around Function objects.
ActionScript 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.

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?
