Number.floor appears to be a valid function but is not. Causing crashes on mobile.

Question

This is a cross post from http://forums.adobe.com/message/4993660/ We didn't get an answer there and this issue, and similar discrepencies between what the IDE can compile and what will run on a device, have been costing us man days in work.

We recently had a problem where when compiling using FB and debugging on devices works fine. But when we built the app using Ant, it was crashing on Android devices. After debugging that, we found that Number.floor was not a function.

I cannot find any documentaiton that says Number.floor was ever a function in ActionScript/Flex/AIR.

So why does Flash Builder seem to think it's valid, let us compile it, and even run it on the device?! Is there some 'even more strict' compiler option I need to check?

Yup. And then it crashes on the device.

i reported the problem for the next version of Flash pro and Flash builder.

it appears the bug was introducted in flash player 11.3. earlier fp versions correctly identify errors when applying Math class methods and properties to the Number class.

i've never heard of Number.floor. where is documentation for that?you probably want to use Math.floor()
