I would like to convert a hexadecimal number to its equivalent double precision floating point number. I couldn't find a function for this. Eg: hex='400a666666666666' floating point=3.3 I need double precision floating point as variable need to be signed with a large range.

How can i remove zero floating points but save none-zero floating points, like this :
21.00 => 21
21.02 => 21.02
I'm trying to get the total to increase by .01 and it works fine up until 6 clicks where it shows .0600000000001 how can I fix this? This is my code so far..

I'm dealing with a problem of floating point unprecision.an equation should be giving out 1, but it gives 0.99999999997 or something.I want to turn it into 1. but i dont want to turn it into 1 if it is 0.97. because then obviously it isn't due to floating point unprecision.
View 4 Repliesin xxxx.mxml (from flex) i have called the remote remote method (of java) the method return type is float
in the xxxx.mxml's remote objects result handler i need get the float values as Numeric String..i tried with string...i did Alert.show to see the value some times i get exact value for eg, 0.5 is the value returning from java methid but here it will show 0.50000454. how get the exact value?
I am working on a Real Time Strategy (RTS) multiplayer game, primarily working from this source: [URL] - which is basically boils down, to running a simultanous 100% deterministic simulation on all clients, and only transmit User input. Which brings me to the Number type, which is a float, which cant be trusted to be the same on all systems, and that could desync the simulation? how to work with Floats in AS3, to make them deterministic/correct errors, or just dont use them at all?

But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
Having a problem with a little animation involving balloons floating in and then floating out again when a condition is met. There are two ways they can float in or out: from left to right, or completely randomly. I actually like it as coming in (left to right) and going out (random) but it's essentially up to the user.
Since I moved my Array sort code into the function that basically deals with telling the balloons to float off though, I've been having problems. Sometimes one or a couple of the balloons will not float off and I'm kind of boggled as to why. Because it works fine IF the Array sort part is outside this function, I'm wondering whether, when the for loop at the bottom starts running, the Array is still being sorted and that's why some balloons get left behind.

Using the ArcGIS Server Flex API, is there a way to convert mouse coordinates on the screen or the a map control to spatial coordinates in the map? It seems like there's functionality to convert map points to screen points, but a function for converting in the other direction seems weirdly absent.

What am i doing wrong?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.

View 1 RepliesI am trying to develop a Quadratic Bezier Curve using the graphics.curveTo() method. Initially when i drag mouse to draw the shape, i use start point and end point of mouse to draw the curve line. I assume control point at any position below or up to the line. An draw the curve using this control point. some what like:-
[Code]...
Now i add a tip on this curve segment. I have x and y position of tip. I want to change the curve segment by dragging tip. but now i don't have the exact control point according to tip position. If i use tip coordinate as control point it reduce the height of curve and now tip does not lie on the curve segment. What i have to do is calculate the exact control point on the basis of tip coordinate. But i failed to get this point.
how to use these in order to make an object move from point A to point B in an arc.Think of that classic game where you have to input the angle and power and try to hit your opponent.
View 1 RepliesI'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.
http:[url]....
I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.
From the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?

View 2 RepliesI'm trying to embed Flash movie (MP3 player) to HTML using SWFObject. The SWF is 30px high but when you roll over some elements, the height can go up to 100px because some elements show up. What I want to do is to have div 30px high but when I roll over particular Flash elements, then the elements that should show up are not visible. I was wondering if there is a way to allow Flash to 'float out' of the div so the taller elements become visible when rolled over the Flash movie.
