Transform.position to 64 bit precision in Unity 5?

Hello to all,
I read that Unity 5 now is working at 64 bit.
My question is simple.
It’s also the transform.position with 64 bit precision? so I can use a double instead of a float type?
I need this feature because I’m working with the solar system.

Thank very much.

No, it’s the memory space that is 64bit. Transform still have 32-bit floats.
