AnyChart Team has found in Flash Player 11.0.1.152 a very weird bug that doesn’t manifest itself in the Debug version of Flash Player, but ruins math in the regular version, so we had to debug it in the non-debug version: using ExternalInterface and JavaScript console.<\/p>\n

Bug description<\/b><\/p>\n

In the regular version of Flash Player 11.0.1.152 the following expression:<\/p>\n

1\/Math.abs(0)<\/code><\/p>\n

is evaluated as -Infinity<\/i>, but in the Debug version it is (as anyone expects): Infinity<\/i><\/p>\n

Reproduce<\/b><\/p>\n

Here is a sample code you can use to reproduce this issue:<\/p>\n

package {
\n    import flash.display.Sprite;
\n    import flash.external.ExternalInterface;<\/p>\n

    public class MagicWorld extends Sprite {
\n        public function MagicWorld() {
\n            ExternalInterface.call(\"alert\", \"1\/Math.abs(0) = \" + (1\/Math.abs(0)).toString());
\n        }
\n    }
\n}<\/code><\/p>\n

As soon as you have done this \u2014 compile and run the sample in the Debug and Regular versions, and you will see the difference.<\/p>\n

The bug has been reported to Adobe: Bug#3011557<\/a>
