Just making sure: There were three types of variables: Integer, string and real.
Was the "real" variable type the one you get when you use the "float" command? The one that would recognize numbers between zero and 1?
I thought I'd better ask before I decide to get comfortable and make mistakes.
Thank you.

Real is a float. Real was to signify the 'real' number, not just rounded.

Right, thanks for the reassurance.
