Can the low and high ends of the observation shape vary?

[FLOROID]

Hey, it's me again.

I've gotten a whole lot further since the last time I posted :)
This time I wanted to ask if passing in parameters with different ranges is allowed or detrimental to the Learning Engine working?
Apart from all of my unsigned floating point variables I also need to pass in a few unit vectors which I've split into float values.
The issue with this is, that obviously these can contain values down to -1.0

Is this problematic or can I just use them like that as long as I define the right range?
