I'm aware of nothing in the e00 file structure that passes as a scaling 
factor.  I've searched the format, but perhaps I'm missing something.  The 
best authority I know of for the format is Dan Morissette's paper at:

http://pages.infinit.net/danmo/e00/docs/v7_e00_cover.html

perhaps someone else can find a reference to a scaling factor of some kind.  
In the absence of a scaling factor it appears that the values must have been 
multiplied by 10 before the e00 file was created.

Not related.

I didn't notice any such thing with the files I imported recently and most of 
those data were floating point.   Because of the nature of the data the 
problem might not have been obvious even if it did occur.
