Can I assume Flash and PHP will generate the same floating point numbers?

floating-point

In a multiplayer game I'm developing, we have a few values that are floating point numbers. The back-end (in PHP) and the front-end (in Flash) occasionally perform the same calculations on these numbers, to minimize communication.

I am currently making sure that both sides are using 64-bit doubles, but am I safe to assume that all calculations will be the same?

For instance, what about string to float conversion - should I worry about Flash having a potentially different implementation as PHP? (If this happens, our game will go out of sync - the client will think it is in one state while the server is in another)

With some testing, it appears to be the same, but I'm just not sure. Can someone clarify this for me?
