Math.floor bug in Flash

[Tom]

Hi!

There is a bug in flash Math.floor(), Math.ceil(), and Math.round().
If a Float number is greater, than MaxInt, then the above functions return values are wrong.

eg.:

var f:Float = 1411051769698;
trace( Math.floor(f) ); // output: -1992470686

In pure AS3 this is works very well.
Can be use the native Math functions in flash somehow?

Cheers!

I found a solution for AS3. In Flash the Number type has a toFixed() function, which is a round function.

So the untyped (f - 0.5).toFixed(0); give the correct floored value, but this is a hack, and the Math.floor will give error any big Float number.

I think that is because it returns Int and result is unspecified for these numbers, as stated in the doc. Try Math.ffloor.

Thanks for you comment. I didn't know about ffloor, and it is working as expected.
